The invention relates to mirror back paint resin and curtain flow coating. It includes 50-70% medium oil length alkyd resin, 20-40% acrylics monomer and pre-polymer, and 5-10% phenolic resin. They are mixed to form finished product resin. Its viscosity is 100-300s; acid value is under 5mgKOH/g. The coating is formed by the resin, proper cross-linking resin, pigment, extender pigment, auxiliary agent, and solvent has low curing temperature, high-speed, high hardness of paint film, good flexibility, adhesive force, and chemical resistance. It can be applied to our country silver mirror production line to ensure the product quality. |
