Application |
AO-38 provides outstanding thermal and color stability to a variety of coating resins upon exposure to high temperatures during synthesis and subsequent processing. It is particularly suited to stabilize alkyd and polyester resin based coating systems that are often used in applications such as l industrial powder coatings (electrical and gas oven heating) l coil coatings l other industrial high bake coatings It is also suitable for polyolefins and can be a good alternative to P-EPQ particularly in LDPE/LLDPE due to its very high compatibility and solubility. In the presence of NOx, a combination of AO-38 with AO-1010 or AO-1076 typically leads to good synergistic performance improvement to discoloration. |
