The photostabilizer UV770 is a low molecular weight hindered amine photostabilizer, which has the characteristics of good compatibility, low volatility, good dispersion, low mobility, good thermal stability and high optical stability, and does not absorb visible light and does not affect color. For the high surface and thick section of the narrow band, molding, there is excellent photostability. With the high molecular weight light stabilizer and ultraviolet absorber, the synergistic effect is significant.
Mainly applicable to: polyethylene, polypropylene, polystyrene, olefin copolymer, polyester, soft polyvinyl chloride, polyurethane, polyformaldehyde and polyamides, adhesives and seals and so on.
Recommended addition amount: generally 0.05-0.60%. Appropriate tests shall be used to determine the appropriate amount added in the particular use.
Packed in 25 Kg / carton. Or packed as per customers requirements.
Store in a cool, dry and ventilated place; avoid direct sunlight.
