Hindered Amine Light Stabilizer
Uvasil 299 is a Hindered Amine Light Stabilizer (HALS) that protects organic polymers against the degradation caused by exposure to ultraviolet radiation.
The unique molecular structure of Uvasil 299 affords powerful UV-protection with good compatibility with many leading polymers. Uvasil 299 is especially effective in polypropylene, but is also suitable for other polymers including polystyrene, ABS, HDPE, polyamides and TPU. It can be used in conjunction with other light stabilizers, antioxidants, lubricants and antistatics. It provides excellent resistance to water extraction and continues to protect oligomeric products after washing or dry cleaning. Uvasil 299 offers outstanding activity under extreme conditions in both thin and thick articles.
The use of proper protective equipment is recommended. Excess exposure to the product should be avoided. Wash thoroughly after handling. Store the product in a cool, dry, wellventilated area away from incompatible materials. Unless stated, proper storage will permit usage of the product for 6 to 12 months from the date of receipt. For additional handling and toxicological information, consult the GLCC Material Safety Data Sheet. |
