M-1 (M1) Structural Construction Adhesive and Sealant
M-1 Structural Construction Adhesive and Sealant is a solvent free, 100% solids Structural Construction adhesive and sealant that will not shrink or slump. M1 Adhesive Can be applied vertically and overhead. M-1 skins over in just 20 minutes increasing its resistance to dirt pick up. M-1 is paintable in 24 hours and works in standard caulk guns --no special equipment required! Download our M-1 Technical Data Guide From Chem link
M-1 Structural Adhesive and Sealant is a moisture curing, polyether adhesive and sealant specifically designed for applications where other adhesives and sealants fail. M-1 structural adhesive and sealant is designed for application in damp, dry or cold climates. M-1 Will not shrink when it cures and is solvent free --it contains no isocyanates.
Application Performance Standards:
ASTM C-920, Type S, Grade NS, Class 25, Uses NT, T, M, G, A and O
Federal Specification TT-S-00230-C, Type II, Class A
Corps of Engineers CRD-C-541, Type II, Class A
Canadian Standards Board CAN 19, 13-M82
AAMA 802.3-08 Type II, AAMA 803.3-08 Type I and AAMA 805.2-08 Group C.
M-1 Structural Construction Adhesive and Sealant will not discolor due to UV exposure and does not out gas or bubble even on damp surfaces. In most cases M-1 does not require a primer and can be used with metal, wood, concrete and many other surfaces. M-1 has excellent adhesion and elastomeric properties. M-1 Structural Adhesive and Sealant is capable of joint movement in excess of 25% (compression and extension.)
M-1 complies with Green Standards. It is LEED 2009 accredited for new construction and major renovations: Low Emitting Materials (section 4.1) 1 Point. It also meets NAHB Model Home Building Guidelines: 5 Global impact points. M-1 is VOC compliant at 240 degrees F: Less than 20 grams/liter (including water), ASTM D2369, EPA Method 24.
