M1 ultra-low VOC structural adhesive and sealant for cleanrooms
M-1 is a non-toxic, ultra-low VOC, versatile construction adhesive and sealant for cleanroom use. It's a heavy duty product made for areas where outgassing and solvents are not tolerated. It releases virtually no molecular air contamination and contains no isocyanates, which is why it was designed for biomedical, electronic and aerospace cleanrooms.
It can be applied in damp, dry, and cold climates down to 30 °F and won't outgas as is common with most urethane sealants. 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, and is paintable within 24 hours.
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, fiberglass, FRP, wood, EIFS, block, brick, EPS foam, concrete and stone.
M-1 is very similar to Chemlink's Novalink, an all-weather construction sealant. M-1 has lower viscosity, shorter skin-over time, higher shear strength, and it 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 roof types, TPO primer must be used first.

Surface or Product Preperation
Surface should be clean, dry and free from all contamination including: dirt, oils, grease, tar, wax, rust and any other substance that may
inhibit the sealants performance. DO NOT use petroleum solvents such as mineral spirits or xylene to clean your surface before using this product. Instead, remove all dirt, oil, loose paint, frost and other contaminates with alcohol. Horizontal applications will require tooling. Allow treated wood to cure for six months prior to application. Do not use in areas subject to continuous immersion of water or chemicals. Do not use on TPO without Chemlink TPO Primer.
