Do I need a different glues for different temperatures?2018-07-19T09:05:48+00:00

Do I need a different glues for different temperatures?

Lash glues cure by moisture.

The catalyst is moisture / humidity on the parts to be bonded.

If there is very low humidity – parts are very dry – the adhesives will take much longer to cure.

You can have very warm environment but if there is no humidity the adhesives will take longer to cure.

When calculating an increase in temperature having an effect on cure speeds this is all linked to having the right levels of humidity also.

A rule of thumb – for every 10C hike in temperature you can halve the set speed. But this is all linked to having the right levels of humidity.

Very low humidity – slow cure.

Also – less is more

Applying too much adhesive slows down the set speeds.

Thin glue lines, correct level of humidity around 55% and temp between 20C-24C. BEST.

An all-rounder from Optimum range is our glue 02.

Also our primer pH balance and our retention plus creates a surface that is slightly on the side of alkaline. This makes the surface more reactive and sets the adhesive quicker.

It helps to take the guesswork out of creating the right environment.

However best environment is always advised.

Hot weather2018-07-09T09:56:08+00:00

Hot weather.

A 10% hike in temperature can double the curing time of lash adhesive.

If a technician uses a very fast glue it may have cured before it is applied to the natural lash causing poor retention.

What can you do?
Go down to a slightly slower setting glue
Put glue beads on jade stone more often ie every 10 minutes
In hot weather your glue may feel more gloopy and you can encounter more brush offs and poorer retention
Do not try to just switch glue.

Make sure your environment temperature and humidity is spot on for your adhesive according to instructions
Vigorously shake for a few minutes then let it settle / tap the side of bottle

Discard the first drop that may be stuck in the nozzle and use the second drop.

Dispensing adhesive
Hold vertically and squeeze evenly
Clean nozzle (but NOT with cotton)
In hotter weather you can despense a larger bead as will cure slower or change the bead more often

Dip always from centre of bead where the adhesive is wettest

If you find the glue is drying too slow pick up smaller amounts
If drying too fast pick up a large amount of adhesive onto the extension and disperse onto onto the natural lash with a back forth motion to spread .

Keep your work area cool
Correctly store adhesive in cool dry place out of direct sunlight
Thoroughly cleanse lashes if client is wearing more sunscreen etc

Optimum lash glues are

 EU manufactured and cover all regulations.

A blend of many of the best properties of lash adhesives to create a superb next generation adhesive

Our full lash system has been created to prolong the retention of the lash extensions.

How can i control the vapours of your glues – Good working environment is key.2018-07-09T09:22:08+00:00

Good air movement.  This is vital around the working area and clients face.

Glue vapours are heavier than air and if no air movement is present the vapours can drop and also stay around the working area for longer.

Local extraction if possible at the work area

Do not leave opened containers around work area

Humidity & room temperature levels need to be continually monitored – keeping within parameters for best bonds and to minimise vapours.

Also by using our unique Retention Plus product applied AFTER the full set has been applied the glue will be cured fully in less than 30 minutes so reducing vapours and thus reducing chance of sensitivities.

What are the glue levels and fumes / vapours of each of each type of glue2018-08-25T09:11:01+00:00

Ethyl – has quite a strong characteristic odour

This is our stronger glues, but vapours can be controlled by correct working environment and good airflow around the working area.

Ethoxy – No odour or very little – this is our sensitive adhesive

Can you guarantee your glue will be covered on my insurance2018-06-22T11:38:03+00:00

Optimum adhesives are EU manufactured, fully safety assessed and fully compliant.

But you will have to check with your insurance. The adhesives have been safety assessed by an independent toxicologist who has the experience to ‘conclude’ the adhesives are safe for sale

Where are your glues manufactured2018-07-09T09:23:15+00:00

EU

Can the glues be stored in the fridge2018-02-26T12:21:33+00:00

Yes – Un-opened. Do not store back in the fridge after they have been opened. Always allow the adhesive to come up to room temperature before opening / use.

What is the correct storage and shelf life of Optimum Lash Glue2018-07-09T09:24:17+00:00

Unopened bottles should be stored in a cool place . Do not freeze the adhesive and do not store them with other chemicals, such as lash lift products.

Shelf is 9 months unopened, 3 months opened.

Keep lids on or replace lids at all times to avoid moisture getting in the glue.

Store in cool dry place out of direct sunlight and away from moisture

What are the retention times of each of your glues2018-08-25T09:14:39+00:00

This is hugely dependant on good lash preparation and techniques of lash application.

If using our full Optimum lash system the retention will improve using our primer/PH balancer and retention plus

Are your glues ISO approved2018-06-22T11:42:44+00:00

Optimum lash glues have been independently safety assessed by a toxicologist for safety.  This is much more relevant to the lash industry than ISO.

ISO 10993-5:2009 describes test methods to assess the in vitro cytotoxicity of medical devices.  These methods specify the incubation of cultured cells in contact with a device and/or extracts of a device either directly or through diffusion.

Are your glues solvent free2018-02-26T13:33:08+00:00

Yes these adhesives are solvent free one-component adhesives systems.

What are the scientific facts about formaldehyde in lash glues2018-08-25T09:17:12+00:00

Formaldehyde must be used in a pre-manufacturing-process.

During the purification and distillation phase almost all Formaldehyde is taken out again, but impurities will always remain.

As Formaldehyde is not an ingredient that is ‘added’ so many say formaldehyde free.

About formaldehyde2018-02-26T11:24:27+00:00

Formaldehyde is used in the manufacturing process to achieve a certain reaction. A chemical reaction that produces water.

This water is then evaporated as temperature increases in the manufacturing process. The water evaporates and the remaining product is the CA monomer. There will always be traces of formaldehyde left in the monomer.

Is your glue formaldehyde free2018-02-26T11:23:56+00:00

There is no such thing.

Is you glue latex free?2018-02-26T11:22:00+00:00

Yes

What are the scientific facts about oils with lash glues.2018-08-25T09:22:38+00:00

From the physical point of view the tension of the surface of the liquid plays an important role. Surface tension means the ability of a fluid to moisten a solid object. If the oil / solvent has a low surface energy the fluid runs over the whole surface and can infiltrate the adhesive layer. If the oil / solvent surface tension is high the fluid contracts and does not spread very well. There is little chance of infiltration.

So it would also be relevant what type of oils are being used.

However, normally we would suggest using oil / solvent free products. The glue lines are so thin on lash extensions. To achieve the very best, long-lasting bonds – protecting the adhesive layer from solvents, water included, oils etc is very important.

However, by using our brand new to the market activator – Retention Plus applied thinly to the glue line after the full set is applied, this will make the adhesive  bonds oil and waterproof in less than 30 minutes, as adhesive will be significantly more cured than left to cure on its own.  Plus adhesive bonds will remain flexible.

Are Optimum lash glues instantly oil proof2018-08-25T09:23:35+00:00

Yes within 30 minutes when using our Retention Plus product after the full application.

What are the scientific facts about how glues actually cure.2018-07-19T10:24:30+00:00

Cyanoacrylate adhesives polymerize, respectively cure by the catalytic activity between the humidity in the air and the humidity of the adherents. Cyanoacrylate rapidly polymerises in the presence of water forming long, strong chains, joining the bonded surfaces together.

Can take up to 24 hours to fully cure.

However, Optimum is a lash system and by using Optimum Retention Plus after the full set has been applied the adhesive will be cured in les than 30 minutes. Also by using Optimum Primer/PH balancer the natural lashes are the correct PH to cure adhesives correctly too.

Are Optimum lash glues instantly waterproof ?2018-07-19T10:23:18+00:00

Lash glues take 24 hours to fully cure that is why we mostly have the ‘don’t get lashes wet for 24 hours ‘ rule.

But by using our Retention Plus after the full application the glue bonds will be fully cured in less than 30 minutes creating a waterproof result and so not having to wait the usual 24 hours.

Are your glues rubberised and what ingredient is this. Do they contain actual rubber ?2018-02-26T11:19:52+00:00

Optimum lash glues are superbly flexible and resistant to very cold weather, but do not contain any kind of rubber.

What is the viscosity for each Optimum lash glue in the range?2018-07-19T10:22:17+00:00

Glue 01 thinner

Glue 02 medium- thin

Glue 03 medium

About Temperature2018-02-26T11:19:06+00:00

Temperature influences the time of the chemical reaction very much. Generally it can be said that a 10°C hike in temperature results in twice as fast polymerization time. This is equally valid for Cyanoacrylate adhesives. The optimal room temperature for curing of these adhesives is between 20 and 24°C.

what are the best temperature for Optimum lash glue.2018-02-26T11:18:27+00:00

20-24C

About Humidity2018-02-26T11:18:05+00:00

Cyanoacrylate adhesives polymerize, respectively cure by the catalytic activity between the humidity in the air and the humidity of the adherents. The higher the relative humidity is (e.g. in a room) the faster the product cures. Best atmospheric conditions for good, reliable bonds are between 50 to 75 % relative humidity.

If humidity is too low (< 30%) setting time can become very slow; if humidity is too high (>80%) a so-called shock polymerization takes place. The latter provokes a certain shrinking process of the adhesive layer, which leads to less bond strength.

Can Optimum be used in humidity like 20% and over 70% – how would this affect the glue and set speeds.2018-07-19T10:18:18+00:00

Yes. But with such low humidity you would need a highly reactive adhesive. It would take longer to set, slowing down initial ‘grab’ of the adhesive and anything outside of the bond area – wet ‘ adhesive would take longer to dry. Making the chances of sensitisation higher as the adhesive would need to find moisture to polymerise. With moisture around the eyes this is the first place it would be attracted to.
