1 General description
In view of the defect that dacromet coatings surface hardness is low, and no acid and alkali resistant,we learn from the advanced technology formulation,develop and produce JH-9323 dacromet coating, water-based dacromet coating,can not only increase the dacromet coatings surface hardness,acid and alkali resistance,and can improve the anti-corrosion performance of the coating (SST≥1500h).Have good adhesion with dacromet coating,and has many colors. Coating process is similar to dacromet coating,your first choice of dacromet top coat.
2 Perfomance charcteisic
This product is with acrylic acid copolymer resin, nitrocellulose, toughening agent and organic solvent as main base material, adding other additives mixed into.The coating layer is smooth, weak acid and alkali resistant, can be adjusted to any colour with paint.
