M-1CR (Cleanroom)

Chemlink M-1 CR (cleanroom) is solvent-free, extremely low VOC, moisture curing, polyether adhesive-sealant designed for application in areas where outgassing and solvents are not tolerated. It releases virtually no molecular air contamination and contains no isocyanates. M-1CR will not shrink upon curing, will not discolor when exposed to UV light, and can not out-gas on damp surfaces as is common with urethane sealants. The product has resilient elastomeric properties and excellent adhesion to most construction materials.  M-1 CR is designed for environments where molecular airborne contamination can impact human health or clean room manufacturing operations and is specified for biomedical, electronic and aerospace clean rooms.
