Product Description
M-1® is a moisture curing, polyether adhesive sealant designed for applications in damp, dry, or cold climates. M-1® is solvent free and contains
no isocyanates. M-1® will not shrink upon curing, will not discolor when exposed to UV light, and can not “out-gas", or bubble on damp surfaces as
urethane sealants often do. M-1® is capable of joint movement in excess of 25% in both compression and extension. M-1® can be used effectively in many
difficult construction site conditions such as wet or dry climates and at temperatures as low as 32°F (0°C).
