Improving fire retardancy protective coatings

Certain chemicals intumesce and form a heat-insulating mat of spongy tough cells. Experiments with various fire-retardant coatings and paints indicate this to be the most effective type of protection so far developed. If the paint qualities can be improved to meet requirements for high-quality exterior paint without sacrificing any of the fire-retardant ability, there is no question of a wide market for the product. [Pg.25]

FIRE RETARDANT COATINGS BASED ON PERCHLOROVINYL RESIN WITH IMPROVED ADHESIVE PROPERTIES TO PROTECT FIBERGLASS PLASTICS... [Pg.77]

To improve physical and mechanical properties of coatings and characteristics of fire protection efficiency, the fire retardant coatings including PEDA as a modifier and based on perchlorovinyl resin (PVC resin) were obtained. The coatings are used for fiberglass plastics. [Pg.79]

A munber of nitrogen derivatives of phosphoric and polyphosphoric acid (ammonium polyphosphate, melamine pyrophosphate) are used for improving the flame retardance of polyurethanes and other polymers. In thermal decomposition these compounds produce ammonia and the corresponding phosphoric acids which catalyze dehydration and other reactions, causing polymer dehydration during combustion. The coke produced in this process is more or less foamed. Ammonium polyphosphate and melamine pyrophosphate are added to compositions of intumes-cent coatings used for fire protection of various structural elements in construction... [Pg.218]
