Features of solvent-free epoxy coating
1. Thick film formation, not easy to produce cracks
Solvent-free coatings have the characteristics of thicker one-time film formation, good edge coverage, small coating shrinkage, small internal stress, less cracking, less organic matter volatilization, and beneficial to environmental protection.
2. Reduce paint consumption
Due to the non-volatile or very low volatility of solvent-free coatings, its high solid content and thicker film formation at one time, the amount of material used can be reduced under the same film thickness. Compared with solvent-based coatings, the paint consumption per unit area can be reduced, and because the thickness of the film is extremely high, the construction time can be reduced. The construction of Chenguang solvent-free coatings, a good construction team, and a high market reputation have saved the factory the production cycle of coating, reduced the consumption of coatings, and the factory saved costs and improved efficiency. Therefore, although the price of solvent-free paint is higher than that of ordinary epoxy paint, the overall cost per m2 is not high.
3. Conducive to environmental protection
Since solvent-free coatings contain very little or no volatile solvents, such as the solvent-free coatings used in container ships only contain less than 5% solvent, it can reduce the air pollution caused by solvent volatilization. The use of extraterrestrial solvent-free coatings reduces the emission of organic volatiles, and also plays an immeasurable role in personal protection, fire protection, and explosion protection. Solvent-free coatings have played a significant role in the implementation of VOC safety standards in our shipbuilding industry. Now the United States, Denmark and France all have strict VOC regulations. I believe that in the near future, China, which is paying more and more attention to environmental protection, will also formulate strict VOC regulations. By then, the large-scale use of alien solvent-free coatings in China will not be possible. Avoided. In addition, another advantage of alien solvent-free paint is beneficial to painters. For them, the possibility of explosions in the paint works in the cabin is greatly reduced, thereby enhancing the safety of the paint construction process.
