Product Features & Advantages
Excellent tensile and tear strength supports hundreds of replication cycles, extending mold lifetime. It features strong weather, temperature, aging and acid resistance for stable long-term use. Favorable tension and deformation resistance maintain dimensional accuracy for complex sculptures. Low viscosity ensures smooth pouring and easy de-airing, with simple operation for all skill levels. 20–40 Shore A adjustable hardness fits small delicate crafts and large statues. Long shelf and service life reduce replacement frequency and overall production costs.
How to Use
Step 1: Clean the master model thoroughly, apply release agent (detergent, soapy water or Vaseline), weigh 100g Part A and 2–5g Part B, then mix evenly. Keep all tools clean to prevent curing failure.
Step 2: Perform vacuum defoaming for about 5 minutes (max 10 minutes) to remove bubbles, avoiding premature cross-linking.
Step 3: Use pouring for simple patterns (smooth flow & de-airing) and brushing for delicate/large molds (anti-flow, exact detail replication).
Step 4: Demold after 3–5 hours, with 24 hours full curing recommended for optimal mold strength. Curing time can be adjusted by ambient temperature.
Application Scenarios
Widely used for bronze casting, lost wax bronze molds, concrete stone, cement casting, gypsum/plaster decorations, resin crafts, clay casting, soap molds, ceramic casting, statues, Buddha figures, Christmas ornaments and art sculptures. It improves casting precision, reduces mold damage and shortens production cycles, helping foundries and studios enhance product quality and profit margins.
