Nylon Powder Coating for Printing Roller

Nylon Powder Coating for Printing Roller

PECOAT® PA11-PAT701 Nylon powder is designed for printing rollers, using the fluidized bed dip coating process. It is made of high-performance nylon resin PA11 through a special physical process. The powder is a regular spherical shape; it has excellent physical and chemical properties, excellent wear resistance, low temperature resistance, and flexibility. Excellent adhesion to metal; compared with ordinary nylon 1010 powder, it has more excellent physical and chemical properties.

Nylon coatings have high hardness, excellent wear resistance, good chemical and solvent resistance, good weather resistance, strong adhesion, and excellent comprehensive properties. Printing rollers and ink transfer rollers require coatings with high adhesion, wear resistance, and ease of secondary precision processing. Nylon 11 has more outstanding advantages compared to nylon 1010, with low brittleness, no cracking in the coating during winter, higher adhesion, no curling, and low rework rate. The strong self-lubricating property of nylon coatings reduces resistance and noise and increases wear resistance. The coating also has strong adhesion to metals and is suitable for subsequent lathe and grinding processing. The integration of these advantages makes it very advantageous for printing rollers.
