Ultraviolet(UV) rays can not only cause skin red spot, blackening, aging and so on, but also accelerate the aging of articles, seriously threatening their service life. The anti-UV coating produced by HuZheng can block UV rays with the wavelength below 400nm, and the blocking rate reaches above 99%. The coating has good transparency, so the anti-UV and anti-aging function can be realized, meanwhile original color and style of the base material is retained. PUU-PP is specially used for PP surface, suitable to UV-curing process and convenient for large-scale industrial coating.
It has excellent transparency after coating,
and the visible light transmittance is more than 88% (depending on the light
transmittance of the base material);
The UV blocking rate reaches more than 99%, and the anti-UV performance is
durable;
High surface hardness, effectively preventing scratches;
Good weather resistance, can withstand climate changes such as sunlight,
temperature, damp and heat for a long time.
It is used on the surface of PP substrate to prevent it from UV damage, improve the aging resistance, so prolong its service life.
According
to different shape, size and surface state of the base material, appropriate
application method is selected, such as shower coating, wiping coating or spraying
coating. It is suggested to try coating in a small area before application.
Take shower coating for example to describe application steps briefly as
follows:
1st step: Coating. Select appropriate coating process for coating;
2nd step: After coating, stand at room temperature for 3 minutes to make full
leveling;
3rd step: Drying. Enter the oven and heat it at 80-100 ℃ for 3 minutes to make the solvent volatilize
fully;
4th step: Curing. 3000W UV lamp (10-20 cm in distance, wavelength 365nm)
illumination for 10 seconds, the coating cured.
Notes:
1. Keep sealed and store in a cool place, make the label clear to avoid misusing.
2. Keep far from the fire, at the place where children can't reach;
3. Ventilate well and prohibit the fire strictly;
4. Wear PPE, such as protective clothing, protective gloves and goggles;
5. Prohibit contacting with the mouth, eyes and skin, in case of any contact, flush with large amount of water immediately, call a physician if necessary.
Packing: 20 liter/barrel;
Storage: in a cool, dry place, avoiding sun exposure.
