Characteristics of solvent-free epoxy coatings
1. Thick film formation, less likely to develop cracks.
Solvent-free coatings feature characteristics such as a thicker, one-time film formation, excellent edge coverage, minimal coating shrinkage, low internal stress that makes them less prone to cracking, and reduced volatile organic compound emissions, making them environmentally friendly.
2. Reduce paint consumption
Due to the non-volatility or extremely low volatility of solvent-free coatings, their high solid content, and the ability to form a relatively thick film in a single coat, material usage can be reduced at the same film thickness. Compared to solvent-based coatings, the amount of coating required per unit area is lower. Moreover, given the exceptionally high film thickness achievable in a single coat, construction time can also be shortened. Therefore, although solvent-free coatings are more expensive than conventional epoxy coatings, the overall cost per square meter is actually not higher.
3. Beneficial for environmental protection
Since solvent-free coatings contain very little or no volatile solvents—such as the solvent-free coatings used on container ships, which have a solvent content of less than 5%—they significantly reduce solvent emissions and the resulting air pollution. The use of extraterrestrial solvent-free coatings has greatly diminished emissions of organic volatile compounds, while also playing an invaluable role in enhancing safety aspects such as personal protection, fire prevention, and explosion-proof measures. Solvent-free coatings have played a major part in helping our shipbuilding industry meet stringent VOC safety standards. Today, the United States, Denmark, and France all have strict VOC regulations. We believe that in the near future, China—increasingly mindful of environmental protection—will also enact rigorous VOC regulations. At that time, the widespread adoption of extraterrestrial solvent-free coatings in China will be inevitable. Moreover, another significant advantage of solvent-free coatings is their benefit to painters themselves. For them, the likelihood of explosions during painting operations inside ship cabins is dramatically reduced, thereby enhancing the overall safety of the painting process.
Polypropylene cold-wrap tape is a new type of environmentally friendly anti-corrosion product that is pollution-free and harmless, representing the highest current international and domestic standards for cold-wrap anti-corrosion tapes. It is affectionately known as the "King of Anti-Corrosion." This tape can be widely used in water supply and drainage systems, as well as in the transportation of oil, gas, and coal gas through steel pipelines and underground steel storage tanks in the petroleum, natural gas, chemical, and urban construction industries. It has been designated by the Ministry of Construction and the State Environmental Protection Administration as a recommended replacement for "asphalt fiberglass cloth" and "epoxy coal tar." It features easy application, excellent impact resistance, superior aging resistance, high tensile strength, UV radiation resistance, and strong bonding performance.
The product’s base material is a unique modified polypropylene woven fiber fabric, with a corrosion-resistant adhesive layer made of butyl rubber-modified asphalt. The fiber-based substrate effectively resists creep damage caused by soil stress. Aging tests have demonstrated that its corrosion resistance lifespan exceeds 50 years. All tested indicators significantly surpass the requirements of the SY/T0414—98 standard and fully meet the specifications of the U.S. ANSI/AWWAC209-00 and NACE MR0274-95 standards. It is the preferred choice for cold-applied anti-corrosion tapes for pipelines and represents an excellent cost-performance option for corrosion protection.
