CHARACTERISTICS |
1. Can easy brush to steel in water with good adhesion. 2. Brushing have good shear strength suitably, blasting steel under water have good wetting and adhesion. Coating can be cured under water, it doesn’t be washed away by seawater. 3. Hard and tough film with excellent abrasion resistance, excellent resistance to water. 4. 400 microns of dry film can be obtained by one coat brush. |
