Product Q&A

Q:What is the mix ratio for the two-part polyurethane rubber?

The mix ratio is 1:1 by mass or volume for Component A (polyurethane prepolymer) and Component B (curing agent).

Q:Can the color of the rubber be customized?

Yes, the color can be regulated by adding pigment. The standard appearance is colorless or light yellow transparent liquid.

Q:What is the curing time for this liquid rubber?

The curing time is approximately 24 hours. The gel time varies from 6 to 35 minutes depending on the specific hardness grade selected.

Q:What types of materials can be cast using this mold?

It can be used to cast PU resin, polyester resin, epoxy resin, concrete, plaster, foam, wax, soap, and other decorative moldings.

Q:How should the components be mixed?

Shake both components vigorously, measure equal parts, and mix vigorously for at least one minute. Avoid using drill motors to prevent exothermic cure.
