AkzoNobel Alcogum SL70 Thickener

AkzoNobel Alcogum SL70 Thickener is a hydrophobically modified ethoxylated urethane (HEUR) rheology modifier from AkzoNobel’s Alcogum series. It delivers excellent viscosity control, sag resistance, and gloss retention in waterborne architectural coatings, especially low-VOC formulations. Designed for high shear thinning and efficient thickening efficiency, SL70 ensures robust storage stability and spray application performance without compromising flow or leveling.
