Application recommendations

This product is applied to PU on the surface of genuine leather. It is transferred and sprayed with high-solid roller and semi-high-solid roller. After kneading, crack gloss and hand feel can be obtained. If the adhesive slurry is too thick before printing, water can be added. Do not add solid slurry so as not to affect the burst effect. 100 mesh or 120 mesh hexagonal wheel treatment, the surface is scratch-resistant and the leather feeling is lifelike.
Note: After spraying, printing and direct coating, it must be completely dried, and kneading with water will have the effect of natural bursting. Crack thickness is controlled by the thickness of the slurry layer. The more food, the thicker the crack, the thinner the material, the finer the crack, on the contrary, the thicker the crack.
