Castable Urethanes

BJB Water Clear Polyurethanes

This group of flexible and rigid casting resins has been designed for use in applications requiring tough, tintable and pigmentable materials that will also maintain clarity in outdoor applications.  With an array of hardnesses and working times, these materials are excellent for fabricating parts of all kinds.  The WC series products work well for castings of all sizes and have been used to cast up to 9000 lbs. for one part.  Seek technical advice from BJB to help make the right material selection.
