Action Bond 150 Expansion Joint Sealant


Action Bond 150 is a single component, polyurethane-based, low modulus joint sealant. It’s perfect for use in high humidity environments.

Action-Bond 150 is a novel low modulus expansion joint sealant. It provides a bubble free cure even at very high temperature and humid climatic conditions. This adhesive cures by reaction with atmospheric humidity to produce a joint sealant. It has a 50% joint movement accommodation factor and excellent adhesion on substrates traditionally problematic for PU sealants.
