CRC® white siliconized acrylic latex is based on a 100% acrylic emulsion. It is further modified with special additives to optimize resistance to oxidation, UV degradation and cold temperatures. When cured, a durable waterproof acrylic sealant is formed. CRC® white siliconized acrylic latex bonds to all common building materials and is flexible enough to be used on moving parts. This makes it ideal for applications where expansion and contraction can occur. CRC® white siliconized acrylic latex is flexible which makes it is ideal for painting applications.
