Problems solved by technology

[0002] At present, the effect of transparent epoxy AB glue applied on the surface of renewable resource ceramic boards, artificial marble, and artistic ceramic boards is not good. The main reason is that the transparency is not enough, and the Shore hardness cannot reach 85-90D, and Poor UV resistance
Even if the hardness of some products can reach Shore hardness 85D, there will be insufficient adhesion between the cured epoxy AB glue and the substrate, and the glue layer will crack
In addition, the yellowing resistance in the indoor environment cannot reach 2 years; in the outdoor environment, the weather resistance is poor, the UV resistance is not good, and the yellowing resistance cannot reach 1 year.
The transparent glue of the surface coating / coating of the existing technology cannot meet the aesthetic and lightweight development needs of future energy-saving and environmentally friendly building materials
