Product description

CF25W resin is a sub-amino partially methyl etherated melamine resin with good water solubility relative to  CF25  resin, used as a crosslinker in medium solids or waterborne varnishes, automotive and general metal finishes, with high viscosity and fast curing under low curing process conditions or without the addition of strong acid catalysts. "CF25W is a highly methyl etherised melamine formaldehyde resin with high imino properties. It is a good curing agent for alkyd resins, polyester resins, acrylic resins and epoxy resins. The resin has good solubility with water and can be used in water-based coatings.
