Silicone-Alkyds in Gloss Enamels.
Abstract
Long term exterior exposure studies at Aberdeen Proving Ground, Maryland and in the Panama Canal Zone of air drying gloss enamels prepared from silicone-alkyd copolymers and silicone resin-alkyd resin cold blends are reported. The soya-oil type copolymer enamels had significantly better weathering properties than the specification alkyd enamels; the linseed-oil type copolymer enamels showed only marginal improvement in weathering properties. The cold blended enamels indicated improved weathering properties upon extended exposure but were otherwise unacceptable. A direct comparison of weathering properties in Panama and at APG was made.
