Adhesives

This is something that i thought about before my shoot because i worked with Kelly Monks and Rhian Webster on a film called "Sleep". (Below i have attached some photos) but this film required a model to have 4 chest prosthetics.

The shoot was a night shoot and she had to wear them for 12 hours. We applied them onto her at 3pm and the shoot finished at 4 am. For this applied all the encapsulated silicone appliances with Pros-aide.

For the thinner parts of the pieces and the edges were fine and did not come away. However around the curves pf the breasts there was some issues.

-Possibly that because it was a flat piece. It did not curve like it should and stick to the skin completely.

- I also think that it possibly was the adhesive that we used. And when speaking to kelly in third year she was really unhappy with the pros-aide application and she said ideally for a larger piece on a long shoot Telesis would be a better choice.

Snappy G Adhesive

In the end i decided to use pros-aide because i already had some so i wouldn't have to increase my budget and buy more adhesive, and also it had worked (although not perfectly) with the first shoot and the Film "Sleep". I assumed that there would no real issues. (Oh how wrong i was)

More Research into silicone/ prosthetic Adhesives

I feel stupid for admitting this but i didn't even realise that solvent based glues and water based glues were so different. I know that latex based glue was a thing, and that is shouldn't really be used with silicone. But i was unaware of the issues and precautions that should be taken with different adhesives.

More Adhesive Research

I definitely feel that i need to learn more about different adhesives for different materials and what is expected and used in industry and by different industry professionals. For example in this blog post Todd Debrecini admits that Pros-aide is his adhesive of chouce, and he would prefer to use that when optional.

Therefore i decided to do some research online as well as in the Special Makeup Effects Book by Todd Debrecini. I came across this blog post by Stuart Bray and Todd Debrecini which breaks down all the pros and cons of different glues and when it is appropriate to use them.

Water Based Adhesive

In hindsight i should have used A solvent based glue for this project. apon further research i have discovered that it does not dissolve with sweat like Pros-aide does and also the body heat of the body helps the glue bond, and stick better.

It also would have cut down applicaiton time because it is not a contact glue, you dont have to wait for it to dry on both the prosthetics and the model, you can just stick it straight on the model.

Using A+B silicone as an adhesive

I think that this is a really useful video and Lars Carlsson has some great tips here.

Using clearly labelled syringes with parts A and parts B separately and them mixing them together in a small/bowl or dish, keeps the makeup table clean and professional. It also saves time on application if you do not have to weigh out the different silicones.
He also mentions Kryolan Silicon Adhesive which is not one i had heard of before. so i found it online, on the kryolan website. And found it is quite expensive and probably cheaper to buy telesis if you can.

https://us.kryolan.com/product/silicone-adhesive-strong-bond-30-ml

This product comes in 2 versions - Regular and strong bond. Assuming that the strong bond adhesive lasts longer abd probably better at holding and securing larger, heavier prosthetics.

Tips

He also adds a little bit of flock to eh mixture befor ehe applies it to the face so that he can see where he has places it.
DO NOT USE A LATEX SPONGE WHEN APPLYING THE SILICONE- it will not cure.

Sweat and Heat

Telesis 7 is a pressure sensitive rapid bonding adhesive, and ready to use out of the bottle. It does not require a thinner to maintain fluid consistency when repeatedly opened and exposed to air.

Telesis products have proven to be both safe and highly effective in the medical, makeup and cosmetic industries. All products have been tested by independent labs for dermal irritation and they do not contain any known carcinogens or cyto-toxins.

Telesis Silicone Adhesives and Thinners, 5 & 7: What's The Difference?

Choosing a Telesis Silicone Adhesive is strictly a matter of personal preference. There is no right or wrong adhesive for any particular application, only the individual makeup artist or medical professional can proper determine which Telesis adhesive product is the best choice for their situation.

Regardless of the choice it is important to understand that all Telesis Silicone Adhesives are non-flammable, highly pressure sensitive, medical grade products. None of the Telesis Adhesives or Thinners contain ethyl acetate, and they all have been tested for dermal irritation. They have been proven safe for use on skin. The numbers in the Telesis Silicone Adhesive line simply represents the order in which they have been introduced to the market, and is NOT indicative of adhesive quality or effectiveness.

The only significant difference between the product versions 5 and 7 is the solids content, and the solvent type. This means that the performance characteristics are slightly different with each one. - See more at: http://www.paintandpowderstore.com/proddetail.php?prod=MM-1352#sthash.rH0qLf8O.dpuf
