CRL "TPR" Setting Blocks are compatible with most anything, meaning you
can use them in designs calling for the use of modern structural glazing
sealants. They are formed of a 90 durometer shore hardness thermoplastic rubber
that performs as well as traditional neoprene setting blocks. They are available
in the most asked for sizes of neoprene blocks. They have excellent chemical
resistance, and do not mar or stain surfaces. Job specific testing, prior to
start up, is recommended with each silicone sealant manufacturer.
