M-1 is a versatile construction adhesive and sealant for interior or exterior use. Made for industrial roofing, it can be applied in damp, dry, and cold climates down to 30 °F. It won't discolor with UV light and is capable of joint movement in excess of 25% in both compression and extension. M-1 has a 20-minute skin-over time, is paintable within 24 hours, is non-toxic and has very low odor (20 g/l VOC)! For even lower VOC, try the M-1 CR (clean room) which has only 13 g/l of VOC.
This is truly a heavy-duty adhesive/sealant. Chemlink's M-1 bonds well to most construction materials including EPDM, SBS mod bit, aluminum, galvanized metal, engineered plastics, PVC, glass, stainless steel, fiberglass, FRP, wood, EIFS, block, brick, EPS foam, concrete and stone.
M-1 is very similar to Chemlink Novalink, an all-weather construction sealant. M-1 has lower viscosity, shorter skin-over time, higher shear strength and bonds to a few more materials. M-1 is perfect for more heavy-duty jobs. It's really a structural adhesive as well as a sealant.
NOTE: For TPO roofing, TPO primer must be used first.
Why we like it
M1 is very similar to NP1, a urethane adhesive, except it has less odor and cleans up much easier. This is a product you can rely on for years to come.
