Deuteron® PMH-C

Polymethylurea. Acts as a matting agent. Is free of waxes. As a thermoset, Deuteron® PMH-C in many cases increases the blocking stability of coatings, whenever the character of the used binder shows tendency to thermoplasticity. Is resistant to most customary solvents in use in the coatings industry. Also offers good chemical resistance, very good color fastness, very good dispersing properties and weather resistance. The use in exterior applications is possible practically without limitation. The coatings are recoatable. In certain fields of application the product’s effectiveness in matting can be increased by combining it with small amounts of SiO2. Even in higher dosages, the products specific oil absorption value gives favorable results regarding viscosity increase. Flexibility of the coating will be spoiled only insignificantly by the use of Deuteron® PMH-C as matting agent. With its favorable oil absorption value the product is predestinated for coatings with high flexibility, for instance coil coatings and leather finishes. In powder coatings the presence of DEUTERON PMH-C can improve fluidity and spraying property of the powder coating. The optimum in dosage depends on the required degree of gloss and the character of the used binder. The addition can be 1.0 – 7.0 %.
