POLYTEK 75-80

Poly 75-80 Liquid Rubber is a two-part, liquid polyurethane system that cures (RTV) to a yellow, Shore A80 rubber. This is a pourable rubber, but it can be easily thickened with PolyFiber II Thickener for brush-on application. CALCULATION: Determine volume of the containment area: (L” x W” x H”) = ________ in³ Determine volume of the model: (L” x W” x H”) = ________ in³ Subtract the volume of the model from the volume of the containment area: _________in³ - ________in³ = ____________in³ Divide the result by 27 in³/lb. (the specific volume of most Poly Liquid Rubber) to determine how many pounds of Poly Liquid Rubber are needed: _________in³ ÷ 27 in³/lb. = _________ lb. of Poly rubber
