New found source for rattle can Butyl acetate

[Steve St.Martin]

  I work in the floral biz and a driver, for one of the largest wholesale dist in the north east.  A company called Design Master sells butyl acetate(buty-rate) in spray cans. A great find for the IC guy's who want to spray but do not have the equipment.  So far I have found them to be high in pigments and no dyes.  I remember SiG selling Randolphs in rattle cans, but sig used dyes and opacity was not good.  The cans are expensive, over 6bux wholsale. But, a can goes a long way.   I'm just starting to experiment with this product, so maybe colors may need a white base. And they do have a flat white that covers extremely well for a base.  I believe finishes could be light with this product. They also have clear, metallics, along with the solids.

We've been using DesignMaster on Free Flight planes for years. I cannot imagine that it is fuel proof but I can attest that it is light weight.

 Is it fuelproof would be the question.

Steve,
Just and FYI a simple spray system is the Preval Spray System available at Home Depot and Amazon about $5 for a single unit. Sprays about three coats on a Nobler size ship.

Best,    DennisT

The resin in butyrate dope is cellulose butyrate, compared to cellulose nitrate(gun cotton) in nitrate dope.

Butyl acetate is part of the solvent mixture.  The website MSDS doesn't show any resin in their colors, so the final finish probably isn't fuel proof.  I've tried colored floral wraps, and they aren't fuel or solvent proof either.  With 3M-77 adhesive they can stick pretty well, and if the seams are completely sealed with epoxy they are reasonably fuel proof.

Any of the spray gloss enamels are reasonably fuel proof to exhaust but not so much to heavy, direct spills.  That needs an autobody clear cote.  The overall weight of the finish runs in the range of 1oz/100sq.in. of wing area.  The heaviest color is white(titanium dioxide) which is pretty dense.

My understanding, over the years, is cellulose is the early plastic, I remember melting plastic scraps of of celluloid in acetone to make a clear glue for canopies in free flight. Early celluloid canopies were not glow fuel proof.   If I melted acetate in acetone, the mixture is fuel proof, and can be used to build acetate canopies for scale glow.   The two, cellulose and acetate are two different plastics.  Read the back of a can of randolphs(Brodak) and the fuel proof "buty-rate dope", solids are Butyl Acetate.  On a can of nitrate it is Nitrate Cellulose.   Even new buty-rate is not raw fuel proof very much over 10% notro.  The old 5% Fox Super Fuel did not seem to bother a fresh(er) finish.  I'm glad I am totally electric. But, the pigmentation is why I tried it.  I suspect many will clear coat anyway.

  Yes, it seems to by very high in pigment. That good to know others have discovered it in modeling.  I plan on using it when I paint the Ares.

This could be a great product depending on how it goes on.

Satin finish is great for the 2K clear coat finish.

A quick test will show how the paint works giving a clean tape edge.

Plenty of color choices! I'll say.

I'll give it a try.

Thanks for sharing.
