Problems solved by technology
On the one hand, the composition of the formula is complicated, the production and preparation are cumbersome, and reactive diluents are required. Most reactive diluents are easy to volatilize and have a pungent odor. On the other hand, acrylic substances have serious oxygen inhibition during the polymerization process, resulting in slow curing rate, incomplete curing, hard drying of the cured film, and volume shrinkage during the polymerization process, resulting in adhesion , the hardness and other properties decrease, which affects the application performance of the cured product; on the other hand, the cured product is mostly white or yellow, which also limits its application to a certain extent
