G952 blue-gray two-component cathodic electrodeposition coating

1. Introduction: G952 blue-gray two-component cathodic electrodeposition coating of high solids and low solids pigment slurry consisting of modified epoxy resin, pigments, fillers, additives and other components. 2. Uses: Automotive and parts coatings. 3. Material: Steel and other metallic conductive material (using phosphate-treated steel sheets have better coating effect) 4. Features: pigment paste having the desired thixotropic, no precipitation. Two-component, construction convenient application. It has excellent storage stability and electrodeposition coating. It has a high throwing power. Free of lead and heavy metals, the Department of environmentally friendly products. Controllable electrodeposition coating film thickness. 5. Storage: Store in 5 ~ 30 ℃ away from fire cool and dry place, without open the original packaging shelf life of six months. 6.
