The Crystal Clear™ Series of polyurethane resins were designed for applications that require absolute clarity. These are low viscosity resins that cure at room temperature with negligible shrinkage to a hard plastic. Cured products are UV resistant and are not brittle. Applications include…

For some tissues, the use of formalin (contains 10 – 15% Methanol) is not suitable, we offer the alternative formaldehyde (prepared from paraformaldehyde – contains no methanol) for your convenience.
