From: Lee Devlin Subject: Barrier Creams Date: Thu, 4 May 95 12:38:08 MDT I was wondering what other builders think is the best barrier cream to use. I got a pint of 'Invisible Gloves' from Alexander a while back but it got lost in a move so I had to replace it. It worked pretty well and was easy to apply. The container it came in had a label on it that gave one the impression that someone was making the stuff in his basement. The lid cracked shortly after I started using it so I had to transfer it to another container. But it was easy to apply and dried fast. Recently I ordered some Ply 9 and Series 8 to see if what they were like. The Ply 9 is a gel that comes in a squeeze bottle and is very easy to apply but it's tacky for the first few minutes. The Series 8 looks and feels like white Elmer's paste and is not as easy to apply as the gel, nor does spread as thinly. I left white fingerprints on the fiberglass cloth until I waited for it to dry more thoroughly. I noticed that there's also a spray called Dermashield that's looks pretty expensive but I haven't tried it yet. Whenever I do a layup, I also use latex gloves for additional protection and to make the clean up easier. So what do you use for skin protection while doing composite work? Lee Devlin From: Marc J.

Here's my take on this, after getting a local allergic reaction to the Safety Poxy I used for the Q2. 1) Use barrier cream (not critical, but can't hurt). 2) Put on cotton glove liners (available from Wicks, etc.) These will keep your hands relatively dry. 3) Put on Butyl Rubber Gloves (available in sizes 7, 8, 9 from Alexanders) According to friends in the plastics industry, these are the ONLY material which is completely impermeable to the volatiles in the epoxies. Latex does NOT protect you from the nasty stuff. 4) Put on Latex gloves over the butyl (the butyl are expensive [~$13] and the latex are cheap - throw away after each layup). 5) Wear a carbon filter respirator for EVERY layup. Breathing epoxy vapors can cause a systemic allergic reaction. Please, don't take any chances - even a local allergic reaction is no fun (my fingers would swell up to twice their normal size and itch like mad for 2-3 days) - I don't even want to think about what a systemic reaction might be. -- Marc J.

Dermashield is great. I'm still on my first can (around $24) and I've been using it for 2 years. You only need a golfball size blob of foam. It dries rapidly and works well. I like it better than Ply9.

The salesman that sells the stuff here has an impressive demonstration where he pours acid over his hands after he puts on the Dermasheild. I have been using latex golves for my Cozy project so far though. I tried the Ply9 but found that it rubed off of my finger tips during the layup. Question: will ply9 contaminate a layup? My guess is; not in the small quantities used. Randall
