Polyurea/polythiourea compositions comprising the reaction product of a first component comprising isocyanate and a second component comprising an amine, wherein the first component further comprises an isocyanate functional polythioether-polyurethane and/or polythiourethane, and/or the second component further comprises an amine/hydroxy functional polythioether, are disclosed. Methods for using the coating, and substrates coated therewith, are also disclosed.

Polyurea/polythiourea coatings

The present invention is directed to a coating composition comprising polyurea and polyurethane. Further, the present invention is directed to a coating composition comprising polyurea or, polyurea and polyurethane, and flame retardant. The polyurea is formed from a reaction mixture comprising isocyanate and amine wherein the ratio of equivalents of isocyanate groups to equivalents of amine groups is greater than 1 and the isocyanate-functional component and the amine-functional component can be applied to a substrate at a volume mixing ratio of 1:1.

Coating composition of polyurea, polyurethane and flame retardant

A fire retardant, intumescent, curable composition for use in composite materials has as its principal ingredients a curable resin system and a fire retardant combination of a polyhydroxy compound, a polyphosphate, a nitrogen-containing compound and a polyacrylate monomer. Significant reduction of the flame spread index is achieved.
