PA 170 Nylon powder coating

The powder coating has been widely recognized with no pollution and the advantages of higher utilization rate. In a foreign country, nylon 11, nylon 12 and primer equipped for powder coatings on metal components finishing protect existing application market; it have reported Nylon 1010, nylon 11, and multiple nylon copolymer powder commute The wear of machine parts spray flooded examples in domestic. Regarding a large part for the domestic nylon 1010 and its copolymers, polyamide resin raw material market conditions, I have developed PA170 nylon powder coating, selected through optimization of the formulation. And with a self-developed primer. So that the paint products, water resistance, weather resistance and resistance to chemical media corrosion and ability to respond to temperature fluctuations election to the international level of similar products in the 1990s.
PA 170 three yuan nylon nylon 1010, nylon 6 and nylon 66-three substances copolymer obtained, which mainly nylon 1010. It has good mechanical properties of nylon, but also enable a discussion fat melting point significantly decreased tendency to crystallize be a large degree of control. The right amount of leveling agent nylon remaining layer leveling and corner coverage can be improved; avoid high temperature curing coating yellowing, use a nylon compatibility and non-toxic the hindered phenol fecal antioxidant agent can be added for a hindered amine light stabilizer; requirements for the the many coatings item is to be subjected to long-term ultraviolet irradiation, have a good effect to maintain the appearance of the products, to extend the service life.
Under the premise of ensuring the physical and chemical properties of the coating. Select inorganic, high temperature Yan, fill shaking their compatibility, not only reduces costs, but also improves the dimensional stability and hardness of the nylon coating. Weaknesses is based on nylon and metal adhesion poor moisture absorption rate, susceptible to a variety of media penetration, supporting the development polybutadiene epoxy primer as the main material, due to the large number of epoxy molecular chain extremely groups exist, and have a strong metal and nylon bonded, and polybutadiene, epoxy toughening, so that the primer is able to adapt to the environment of use of substantial temperature fluctuations and the external compression deformation.

PA 170 nylon powder coating characteristics
① spray method is simple and suitable for a variety of processes and complex structure of the workpiece;
② metal adhesion is good, the item after the coating to withstand the rigors of the shaping process;
③ self-lubricating and anti-wear effect is good;
④ weather resistance, resistance to cavitation and chemical medium erosion ability.
