ML-0136 alkyd-melamine-formaldehyde resin

 

   ML-0136 resin is a composition of castor glyptal alkyd (42% oil) and melamine-formaldehyde resin in mixed organic solvents.
ML-0136 is used as an intermediate in production of synthetic automotive enamels, for painting buses and various industrial products used outdoors and indoors, for production of ML-12  thermal drying enamels, hammer enamel, ML-165, and others.
