M-1

Data Sheet

Overview

Overview

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 35% 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).

Features:

  • Solvent free, 100% solids will not shrink
  • Non-slump, applies vertically and overhead
  • 20 minute skin over
  • No outgassing on damp surfaces
  • Good color stability, will not suntan
  • Paintable within 24 hours (See limitations)
  • Gun grade, no special tools or mixing required
  • Application at temperatures as low as 32°F (0°C)
