Trust 7128 resin is used to make metal coatings on the surface of metal, glass, ceramics, marble and other inorganic materials to enhance the decorative properties of the product. It is widely used in various types of wine bottles, cosmetic bottles, and decoration industries. The combination of primer and topcoat achieves both beautiful appearance and excellent protective function.
Formula analysis: 7128 bifunctional polyurethane acrylate provides excellent adhesion properties to glass, metal, and ceramics, and has excellent water resistance.
AM-324 cures quickly, the reaction is completely dull, the volume shrinkage is relatively small, and the side effects on adhesion are relatively small.
7210 resin enhances the bonding force with the coating, but please note that excessive dosage will cause overall adhesion to decrease and insufficient curing to cause fogging of the coating.
370 acrylic series leveling additives have good interlayer adhesion and fewer side effects.
MP-360 multifunctional aminosilane coupling agent can be photocured, react quickly, and enhance adhesion and water resistance.
The appropriate solvent ratio is a mixed solvent of esters, toluene and ketones. 7128 requires a solvent with relatively strong solubility.
7150 resin has excellent adhesion to metal coatings and is resistant to water and solvent erosion.
