Customer field: TPU color masterbatch
Industry problem: TPU products defects are manifested as sticky mold, large viscosity during processing, surface is not smooth, oil, no luster, etc., which adds great difficulty to processing.
Solution: 691 has a very balanced internal and external lubrication, with various strong polar functional groups linked to the main link, which plays a big role in improving the viscosity reduction and wetting and dispersion of pigments during production, and has a stable structure without precipitation.
Chlorinated polyether powder coating is a thermoplastic powder coating composed of chlorinated polyether resin, pigments, fillers and additives. Chlorinated polyether resin has the following chemical structure:
ECH: C-C Hz-O].
The molecular weight of chlorinated polyether resin is about 300,000, and the chlorine content is about 45% (mass). It is a very stable compound from the point of view of chemical structure. The physical and mechanical properties of this powder coating and chemical resistance are very good. Among the thermoplastic powder coatings, the heat-resistant temperature of the coating film is relatively high, and the water absorption rate is small, which is only 1/1/of the rigid polyethylene resin. 10. Mainly used in the lining and coating of valves, pe wax manufacturer thailand pipes and metal tanks with high requirements for chemical resistance.
Polyvinyl butyral powder coating is a thermoplastic powder wood coating composed of polyvinyl butyral resin, pigments, fillers and additives. The transparency of polyvinyl butyral resin is very good, the light transmittance is as high as 90%, and it has high strength, good elasticity, impact resistance and flexibility. In the past, it was widely used in bulletproof glass. In addition, polyvinyl butyral resin powder coatings have good adhesion, wear resistance and self-lubricating properties, similar to nylon powder coatings. This powder coating was developed by Kura-ray in Japan. The new product, the trade name is “Dual val” (Dual val). The technical index of the coating film performance is not high. It is being tested and popularized. The three resin varieties and a powder coating sample provided by the company have been tested It shows that the appearance of the coating film is very smooth, but the impact strength of the coating film is not very satisfactory.
