Lowilite 62 is polymeric HALS having a low melting range for use in polypropylene,polyethylene, styrenics, unsaturated polyester, acrylics, vinyl polymers (PVC, PVB), including plastisols, elastomers, adhesives, sealants and spin finishes. Lowilite 62 typically demonstrates reduced interaction with co-additives such as pigments or other stabilizer and is an excellent stabilizer for systems containing high loadings of carbon black.
