Sauereisen Epoxy Expansion Joint Compounds are used to provide a durable joint filler. They maintain excellent flexibility. The materials are 100% solids, pourable epoxies designed to effectively absorb the shock and impact of heavy loads and steel-wheeled vehicles over narrow joints. Available in two formulations, No. 220 is for general purpose applications and No. 221 is a novolac epoxy for more severe chemical environments.

Sauereisen Joint Compounds are nonshrinking due to their high-solids content and will not become brittle. These self-priming materials will flow and self-level to the full depth of the joint. The joint compounds cure quick enough to be ready for foot traffic in 24 hours and chemical service in 3 days.

To use in vertical joints, add 1/2 to 1 pound of Thixotrope No. 220T (sold separately) to each unit of joint material and mix thoroughly. This results in a viscosity suitable for a caulking gun.
