Fully Methylated Melamine-Formaldehyde Resin
Category：Organic Chemicals
Introduction
DESCRIPTION
MM-803C is a specially-designed hexamethoxymethyl melamine resin (HMMM). With its precisely controlled functionality,MM-803C
shows high reactivity to polyfunctional coating resins. It is recommended for the application in conventional high solids and solvent-borne coating systems. In comparison with butylated amino crosslinkers, only one-half amount of MM-803C is required to achieve superior physical and chemical properties of cured coatings, which includes flexibility,gloss retention, hardness, impact resistance and MEK rub resistance. Among numerous types of methylated amino resins, MM-803C is the most versatile methylated melamine resin.
