50E-1 PET Advanced Optical Transparent Coating


    JXHM50E-1 is a PET advanced optical transparent coating with two-component. It mainly is apply to make the connection material of the diffusion film. The coating that adds diffusion power will form a diffusion film coating. It is especially suitable for making the diffusion film for mobile phone, which is not easy to shrink, curl, excellent softness and elasticity.

Technology and capability index
1.Appearance: clear or light yellow transparent sticky liquid;
2.Viscosity( 30℃mpa.s ) : 5000~7000;
3.Solid content(%):48%±2;
4.pH value: 5~6.5;
5.Light transmittance≥99%.

Using ratio

  • Main agent: Curing Agent (50%Solid content)= 10:1~2
  • Recommended: 10:1.5

Ethyl acetate, or butyl acetate, or the mixture of ethyl acetate and butyl acetate

Collocation method in order
Main agent ( 10 parts ) + diluent (5 parts ~7 parts ) + diffusion powder(appropriate) and stir completely+ curing agent (1.0 parts ~ 2.0 parts) and stir completely again.

1. The formulated coating should be used up within 10 hours after it is ready-made. If continuing to use the remain, first mix the remain and the new formulated coating together, and then the mixed coating should not exceed 10 hours. (if exceed, solidification is likely to come out)
2. Using machine coating, 4 levels of increasing temperatures should be:

  • First stage:60~65℃; 
  • Second stage:70~75℃;
  • Third stage:80~90℃;
  • Fourth stage:100~130℃.

3. Reverse rolling after coating is finished, so that the residual solvent sufficiently volatilizes.Coating speed should be set up according to the coated object sufficiently dries off.(Coating speed as reference is 13-15m/min if length of drying tunnel is 10~15m).
4. Hardening time: after 24 hours at room temperature, then place it into in the solidification room at 45℃~50℃ for 72 hours.
5. Can’t be mix with OTHER COATINGS.
6.To avoid turbidity, please clean up other types of coating, include equipped with plastic tank, plastic buckets and all tools before using the coating.
7.The process ratio in this paper is for reference only. Due to different manufactures are with different technology conditions, raw material conditions and equipment conditions, we recommend that manufactures confirm the pre-tests or consult with us before using. Our products are only sold according to general condition.
8. According to customer demand for products, we can make the overall design of the program, including modifying the product formulation and setting the process methods.
