ABSTRACT:
An improvement in intumescent compositions is provided comprising, in part, melamine formaldehyde resin, a cross-linking agent, and a hydrophilic setting agent. The composition chemically absorbs water to yield an intumescent material with reduced cracking properties which decomposes into gas and a solid foam residue upon heating.
