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).
