Poly 74-30 Clear Liquid Rubber is a two-part, liquid polyurethane system that cures (RTV) to a transparent amber, Shore A30 rubber. This is the transparent version of Poly 74-30 Liquid Rubber. This product is useful for molds where clarity is needed to see casting material fill the cavity. This liquid polyurethane rubber can also be used for casting clear amber or color-cast flexible art objects and décor. Poly 74-30 Clear is a pourable rubber, but it can be easily thickened with PolyFiber II Thickener for brush-on application.


WARNING: This product can expose you to chemicals including Toluene diisocyanate (TDI), which is known to the State of California to cause cancer. For more information, go to www.P65Warnings.ca.gov.
