G-E Silicone Anti-Silk A g e n t Paint manufacturers n e e d add only small amounts of this agent te reduce separation of pigments which causes mottled or streaky p a i n t surfaces. Similarly, t h e "'niante peel" look of certain lac quers can be avoided by adding C-E silicone anti-silk agent.
How did G e n e r a l Electric get into the chemical indus.ry? G . E. has been concerned for many years with improving electrical insulation. In the course of research toward this end, General Electric developed the versatile class of synthetics now known as G l y p t a l * alkyd resins. These held so much promise as paint vehicles that G. E. concentrated on their development for that field. In addition to the Glyptals, G-E research has produced many other products which contribute to the progress of the coatings industry. Some are described here.
G-E 2557 Piasticizer Insulated wire manufacturers can now de sign vinyl thermoplastic insula tion for continuous use at 220 F — thanks to heat-resistant G-E 2557 piasticizer. Its low viscosity results in better extrudability, taster production, and a smoother product. The outstanding light stability a n d weather resistance of G-E 2 5 5 7 make it an ideal piasticizer for nitrocellulose lac quers, upholstery material, and vinyl sheeting and film.

Resists 500 F! G.E.'s new silic o n e resins a r e d e s i g n e d for finishes subject to exposure to temperatures u p to 500 F for long periods of time. Tests show no discoloration or loss of gloss after 1000 hours at that temperature. Weathering tests left such finishes unaffected after three ι/ears of exposure.

Fast-Baking Recommended for use in formulating finishes for a variety of household appliances, Glyptal alkyd resin G-E 2520 has outstanding fast-baking charac teristics, toughness, and adhesion. It may also be used effectively with G-E Glyptal 2572, for ex cellent color retention, and soap resistance.
