80 Durometer Hardness
These CRL Silicone Rubber Setting Blocks have superior durability, are U.V. resistant, and are compatible with most silicone sealants. They will not discolor the silicone should the two come in contact with each other. Job specific testing prior to start up is recommended with each silicone sealant manufacturer.
To ensure sealant to block compatibility, the manufacturer of the silicone sealant can test the compatibility of job site representative accessory materials with their silicone sealants using ASTM C1087-87. Results of the compatibility test will be forwarded in writing. Testing takes approximately four weeks from receipt of samples.
