摘要:
A method includes coating a substrate to provide a flame resistant substrate. In an embodiment, the method includes preparing an aqueous solution. The aqueous solution comprises a phosphate material, a cationic material, and a water. The method further includes exposing the substrate to the aqueous solution to produce a coating on the substrate. The coating includes the cationic material and the phosphate material. The method also includes exposing the coating on the substrate to a melamine solution.
摘要:
A process for making a corrosion-resistant metal component. The process having the steps of: combining water, at least one zinc phosphate compound and at least one chromium compound, being chromium (III) or chromium (IV) compounds, to form a first solution; separately combining at least one silicate compound with water to form a second solution; combining the first solution with the second solution such as to form a mixed aqueous solution; optionally combining the mixed aqueous solution with at least one acrylic resin to form a coating mixture; and, applying the coating mixture to a metal substrate having a zinc or zinc-alloy surface to form a coating on the metal substrate, the coating providing chemical resistance for at least 150 hours in accordance with ASTM B117 standards where the zinc or zinc-alloy coating of the metal substrate has a weight of 0.04 oz/ft 2 (12.20g/m 2 ).
摘要:
Disclosed is an aqueous bonding composition comprising: (A) a saccharide; (B) a phosphate; and (C) at least one neutralizing agent selected from ammonia and an amine compound having at least one hydroxyl group. The aqueous bonding composition is excellent in balance among bending strength, bending strength under wet condition, water-absorption thickness expansion coefficient and peeling strength and scarcely causes metal to rust. The aqueous bonding composition can be usefully used to produce a wood-based material.

摘要:
The present invention relates to the use of aromatic P-N-compounds in flame retardant polymer compositions. These compositions are especially useful for the manufacture of flame retardant compositions based onthermoplastic polymers, especially polyolefin homo-and copolymers, polycondensates, such as polyamines or polyesters and duroplastic polymers, such as polyepoxides.
