Features of solvent-free epoxy coatings
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. 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 solvent-free coatings 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.
Polypropylene cold-wrapped tape is a new type of non-polluting, non-hazardous, environmentally friendly anti-corrosion product. It represents the highest level of international and domestic cold-wrapped anti-corrosion tapes and has the reputation of "Crown of Anti-corrosion". It can be widely used in water supply and drainage in petroleum, natural gas, chemical industry, urban construction, and external anti-corrosion and repair projects of steel pipelines for oil and gas and gas transportation and steel buried storage tanks. It is a recommended product designated by the Ministry of Construction and the State Environmental Protection Administration to replace "asphalt glass cloth" and "epoxy coal pitch". It has the characteristics of simple construction, impact resistance, aging resistance, tensile resistance, ultraviolet radiation resistance, and high bonding strength.
The base material of the product is a unique modified polypropylene woven fiber cloth, and butyl rubber modified asphalt is used as the anticorrosive glue layer. The base material is a fiber structure that can effectively resist the creep damage caused by soil stress. The aging test proves that its corrosion resistance life is more than 50 years. The test indicators are much higher than the requirements of the SY/T0414-98 standard. Reach the American ANSI/AWWAC209-00 and NACEMR0274-95 indicators. It is the best choice in pipeline cold anticorrosion construction tape and the most economical choice for anticorrosion.
