Poly 74-30HT Liquid Rubber
Poly 74-30HT is a high-tear formula of our ever-popular Poly 74-30. It is a 1:1 mix, low-viscosity, liquid polyurethane mold rubber that can be used for all the same uses as any other Poly 74-Series rubber – casting of wax, plaster, concrete, resin, foam and more! Poly 74-30HT uses the same Poly 74 Part A as Poly 74-30, but with a new, high-strength formulation on the Part B side, we are able to provide superior tear and tensile strength in applications where that is important.
Poly 74-30HT can also be mixed with Poly Fiber II to create a thixotropic mix of any consistency needed for brush-on mold applications.
