M-1 is a moisture curing, polyether adhesive/sealant designed for application 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 has resilient "elastomeric" properties and excellent adhesion to most construction materials. 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 and it cures in wet or dry climate conditions and at low temperatures (30*F).
Advantages:
Solvent free, 100% solids, will not shrink
Non-slump, applies vertically and overhead
20 minute skin over, resists dirt pick up
No outgassing on damp surfaces
Very good color stability, will not suntan
Paintable within 24 hours (Some limitations)
Gun grade, no special tools or mixing required
Can be applied at temperatures as low as 30* F
