ASI 174 Siliconized Acrylic Latex caulk is a high performance, paintable sealant used for sealing interior and exterior joints. ASI 174 Siliconized Acrylic Latex cures to form a strong, flexible water tight seal. ASI 174 is further modified with proprietary additives to optimize resistance to oxidation, UV degradation and cold temperatures. ASI 174 will also expand and contract with paint which allows it to be painted using most latex and oil based paints.
