Products Description
One component, high temperature(160℃) cured polyurethane coating ink. It serves as clear transparent protective cover for pattern-printed silicone rubber items ,characterized by dirtproof and abrasion resistance and of high glossy or matty performance, suitable coating solution for silicone rubber products like keypads ,swimming caps etc.
Strong adhesive force Smooth touch feeling
Friction resistance High transparent
Weathering resistance Chemical resistance
1. Cleaning the surface and corona or flame the substrate material.
2. Please stir this coating with well-distribution,and filtrated with 300 mesh filtrating screen for
two times.
3. Spraying coating it on the substrate material.

1. Please stir this coating with well distribution after opening
2.Keeping a good operating environment.The best operating environment should be worked in dust-free working shop, temperature control at 20 ~ 30 ℃, humidity control in the 60 ~ 80%. Too much dust will cause more adverseness, temperature is too low to cause a decline in flow adjustment, adhesion. Shrinkage caused by heavy humidity, too low humidity Easy to create electrostatic potential safety hazard.
3. Flame (or discharge) processed silicon sheet should be used up in 30 minutes, more than 30 minutes have to commencefire (or discharge) processing again
4.Coating will increases the load of elastic wall, and increases with the film thickness increases, the silicone rubber elongation decreased, If there are any aspects of scruples, please consider the methods and coating thickness.
Storage
Stored at a cool and dry place,(-5℃~35℃), far away from heat and flame.
Shelf life
6 months.
