AV-103® Catalyst SP

AV-103® Catalyst SP

AV-103® Catalyst SP (often referred to as SP) is a white crystalline solid used as the initiator for the polymerization reaction of acrylic and acrylate monomers.

Sodium persulfate (SP) is a required acrylic grout mix component and can be increased from 5 lbs. (1% by weight, 60 oz. by volume) to a maximum of 15 lbs. (3% by weight, 180 oz. by volume). AV-103 is a strong oxidizing material which decomposes over time.
