Transparent powder coating production process and precautions

Transparent
Powder Coatings
is one of the powder
coatings
, and its production process is relatively similar to powder coatings, requiring the following production processes:
ingredients → premix→ molten extrusion→ pressure sheet →shred→sieve→ inspection. Because the anti-pollution ability of transparent powder coating is poor, so the whole production process control is particularly strict, otherwise it is easy to shrink holes, noise and other defects.
transparent powder coating production process, every small process link plays an important role in the quality of the final product. Due to the production process need to pay attention to some details:
1, in the choice of curing system must pay attention to, if the melting point of the curing agent and coating film baking temperature is close, then the melting and cross-linking reaction will occur at the same time, resulting in leveling is not particularly good;
2, in the selection of raw materials, to take into account the resin and curing agent reaction product activity, as this will affect the storage stability of the powder;
3, careful screening with high transparency of leveling agents;
4, resin compatibility is poor, to strictly control the production process to prevent cross-contamination;
5, we must pay attention to the transparent coating and the bottom coating matching, to ensure good inter-layer adhesion.
In short, transparent powder coating production process in every detail need to pay attention to, only in this way the quality of the transparent powder coating will pass, in the use of the process is not easy to appear shrink holes, noise and other defects, etc. , in order to ensure that their own home purchase of transparent powder coating quality, so it is recommended that people better find professional paint manufacturers to buy paint!
