PMC™-724

Used by artists and industry the world over for a variety of design, casting and special effects applications, PMC®-724 is by far the most versatile urethane rubber compound available on the market today. It is inexpensive, mixes and pours easily, and will cure to a durable rubber with negligible shrinkage. Low viscosity ensures flawless pick-up of even the finest detail with minimal bubble entrapment.

PMC®-724 PUTS YOU IN CONTROL! Using optional ‘Part D’, you can thicken PMC®-724 to a paste-like consistency for vertical surface brush-on applications or for getting into those hard-to-reach undercuts. If you like to work with a more flexible rubber, optional ‘Part C’ (SO-FLEX®) is available to soften PMC®-724 all the way down to a Shore A6. Typical applications include reproducing sculpture (lost wax process), creating special effects, making fiberglass panel & part molds, on-site architectural restoration and new construction molds. A variety of colors and special effects can be achieved by adding SO-Strong® urethane colorants.
