Product description

Part I: Introduction
★Water-dispersed epoxy ester resin designed for water-borne self-drying paint and water-borne low-temperature baking paint
★It is necessary to add water-based drier to assist cross-linking
★Excellent performance in salt spray resistance, water resistance, weather resistance and high gloss
★Excellent adhesion on all kinds of metal substrate
★Good resistance to hydrolysis.
★Good stability for water based paint

Part II: Physical Characteristic

Appearance	Dark yellow viscous liquid
Non-volatile content（%）	70±2%
Viscosity（NDJ-5S，4#，6rpm，25℃）（mPa·S）	20000-50000
Hydroxyl value	≤30 (when 70% content)
Solvent	BCS/i-PA/n-But

*BCS：Ethylene glycol butyl ether/ i-PA：Isopropyl alcohol/ n-But：N-butyl alcohol

Part III: Typical Applications
★A certain amount of drier to assist cross-linking is needed。
★Can be directly dispersed with water or added alcohol ether solvent
★Can be used with acrylic emulsion after dispersing the resin to about 40wt% by water。
