摘要:
Phosphorus-containing compounds useful for flame retardant epoxy resins are disclosed. The flame retardant epoxy resins may be used to make electrical laminates. This invention is particularly useful in end use applications in which a low bromine or low halogen content is required or desired.
摘要:
A coating composition comprising a polyglycidyl ether of a 2,2′-biphenol that is substantially free of bisphenol A, bisphenol F and their derivatives and residues is disclosed. Food packages coated at least in part with such coatings are also disclosed.
摘要:
Disclosed are oligomeric phosphonates including oligophosphonates, random or block co-oligo(phosphonate ester)s and co-oligo(phosphonate carbonate)s produced using a condensation process terminated with hydroxyl, epoxy, vinyl, vinyl ester, isopropenyl, isocyanate groups, and the like. These materials can be used as a reactive additive to other polymers, oligomers or monomer mixtures to impart flame resistance without diminishing melt processability which is important in the fabrication of polymers for many applications.

These compounds are useful for making flame retardant epoxy and polyurethane resins and ignition resistant thermoplastic resins, each of which is useful for a variety of end uses requiring flame retardancy or ignition resistance. Flame retardant epoxy resins may be used to make electrical laminates. Flame retardant polyurethane is useful for making rigid polyurethane foam used in construction and flexible polyurethane foam used to make vehicle upholstery. Ignition resistant thermoplastic resins are useful for making television cabinets, computer monitors, printer housings, automotive parts, and housings and parts for appliances. This invention is particularly useful in end use applications in which a low bromine or low halogen content is required or desired.
摘要:
A corrosion resistant, alkali resistant coating composition is disclosed. The composition comprises a binder comprising a reaction product of an epoxy-containing material and a phosphorus-containing material together with a curing agent. Aminoplasts, especially melamine-based aminoplasts, are particularly suitable curing agents. A source of silicon can optionally be included. The compositions also provide excellent adhesion and can be used with or without a weldable primer. The compositions are applied to and cured on a metal substrate.
