Technical Datasheet | Supplied by DKSH

DKSH Curing agents

PUREsorb 944 distributed by DKSH is a high molecular weight, oligomeric hindered amine light stabilizer (HALS). It is highly effective as a long-term thermal stabilizer in thin and thick articles.

It exhibits excellent compatibility, high resistance to extraction and low volatility.
It provides excellent light stability to thin articles, particularly fibers and films as well as polyethylene-based thick cross sections articles.
It is recommended for indirect food contact applications.
PUREsorb 944 is suitable for polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers.
It is also used in polyacetals, polyamides, polyurethanes, flexible and rigid PVC, as well as PVC blends and in certain styrenic elastomer.
It is available in USA and India.
