Clean Room Sealants

Meeting requirements for semiconductor, biomedical, and electronics clean rooms, these sealants won’t contaminate air and surfaces. Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain.

Apply these sealants in cold temperatures, on wet surfaces, and even through running water. They are structural sealants that combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. Sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are good for use between dissimilar materials and in environments with wide temperature fluctuation.

All-Weather Application Concrete Joint Sealants

Apply these sealants on wet surfaces and in cold temperatures. They're non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.
