Chemlink M-1 CR Clean Room Sealant

Available in a case of 16 of the 10.1 ounce cartridges

Chemlink M-1 CR Clean Room Sealant is solvent-free, extremely low VOC, moisture curing, polyether adhesive/sealant designed for application in areas where “out gassing” and solvents are not tolerated

M-1 CR Clean Room Sealant 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-1 CR 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.

Product was what I expected and delivered as promised.

Wish I had found you sooner! Arrived quickly, good correspondence. I never wondered what about the status of my order. Wont hesitate to buy from you again.

Not criticisms but observations for what they're worth. Easy purchase but free delivery was slow: October 29 to November 6, 2025. Faster mail service makes this product's market price cost prohibitive on your sight. Time constraints are less a factor for small DYS homeowner projects, but larger project and contractors, it creates an undue consideration. Key and foundational shipping offsets of large big-box stores and online retailers are quantity purchases and 'membership fees,' the latter being the most important key.

I spoke with the person in the Technical Support department who listened and understood my complicated circumstances and made the perfect recommendation. I received the product within a couple of days and before the weekend ended, the job was complete and I am very pleased with results. Thank you, Eco Building Products for your support and product recommendation.
