At the initial stage, the plating crystals are mainly polysiloxane products. Due to its relatively low hardness, limited scratch resistance, poor adhesion, easy to crack and fall off and other shortcomings, the protection effect is very limited, so it needs frequent maintenance. After continuous research, the plating crystals of polysiloxane and inorganic silicon materials are gradually developed, which has improved the quality compared with siloxane products; polysiloxane and inorganic silicon plating crystal cause The film density is high, so it needs to be brightened in a short time. After the film is cured, the hardness is better (5-7h, but the actual hardness of siloxane is generally no more than 3H), the refractive index is better (better brightness), and the adhesion is good (no crazing). Because the adhesion is good, the hardness is high and no crazing, so in addition to the paint surface, it can really protect the paint surface in plastic, rubber, interior decoration, door panel, glass Glass, etc. can be used, car beauty shop is generally used as an all-around plating crystal.
