In complex coating systems, PU transparent primer coatings are mainly composed of resins, solvents, additives, body pigments and polycyanate, perfectly combined into an "excellent" mixture to improve the productivity of furniture factories. Most PU coatings in thick coating drying, due to the surface solvent volatile faster, and the lower chemical cross-linking reaction produced by the gas can not be fully released leading to bubble production, resulting in a series of subsequent disadvantages. To this end, Dabao paint carefully developed
can be thickly coated with anti-foaming good PU transparent primer CR-3222A/GB
.
CR-3222A/GB highlight features:
1
good foaming resistance (thick coating)
product formulation selection release, good dryness resin, scientific adjustment system of surfactant additives, so that material bubbles / mechanical bubbles / reaction bubbles with its help to get better release and elimination.
2
High Perforation
uses a resin with low molecular weight and high tentacles to reduce the surface pressure of the system and allow the coating to wet the substrate more deeply.
3
High fill
product formula scientific introduction of body pigments, improve the proportion of solid composition of primers, so that the wood grain stay in the active ingredients are higher, so that the substrate is stronger, smoother, not easy to sink.
Coating process reference:
Description:
1, the use of CR-3222A/GB can be thickly coated anti-foaming good primer, can reduce the number of coating channels, without affecting the filling effect at the same time improve the efficiency of furniture factory.
2, coating CR-3222A/GB primer, it is recommended that after completely dry, polish and then carry on the next process of coating. (Practical operation, depending on the situation to consult Dabao engineering or technical personnel)
3, primer 25 degrees C, 75% self-drying 4 hours, paint 25 degrees C, 75% humidity, self-drying 24 hours, according to the situation with drying equipment.
