ABS plastics have excellent processing properties and comprehensive mechanical properties, and are used in automotive interior, home appliance shell, home decoration materials and other fields. However, the unmodified ABS usually has the disadvantage of poor weather resistance. With the extension of service time, the impact strength of ABS plastic will decrease significantly, the luster will become worse, and the color will turn yellow.
The main reason for this phenomenon is the existence of double bonds in butadiene in ABS molecular structure. Under the action of light and oxygen, it will accelerate the photoaging of materials, and the cross-linking reaction of main chain will occur, leading to the decline of material toughness and yellowing of appearance. The reasonable selection of UV absorbers is very important to inhibit the photo oxidative aging degradation of ABS plastics and improve its weather resistance!
region. Especially, it has strong absorption for UVB band ultraviolet light with a wavelength of 280-320nm, and the maximum absorption wavelength is close to 300nm.
Our company can supply industrial grade UV3035 and cosmetic grade UV3035, and the content of effective ingredients is more than 99%. Cosmetic grade UV3035 strictly conforms to the GMP production standard and can be used as a highly effective chemical sunscreen in cosmetics and sunscreens.
In addition, NENGYUE UV3035 can also be used in paint and spray paint products to improve the light resistance of resin substrate and has excellent compatibility with acrylic resin. The recommended dosage of various coating resins is as follows:
Acrylic resin 0.5-2%
