Product Features & Advantages
This industrial casting silicone offers a wide adjustable hardness range to match different casting project requirements, with excellent fluidity that ensures smooth pouring and easy operation for all skill levels. It delivers superior mechanical properties, especially high tear and tensile strength, paired with great flexibility for hassle-free demolding without damaging mold details. Featuring heat resistance, effective cut-growth resistance and ultra-low shrinkage, it supports hundreds of repeated duplication cycles, extending mold lifespan and cutting replacement costs. The wide selection of curing agents allows flexible adjustment of operation and curing time, adapting to various production schedules and workflow needs.
How to Use
Step 1: Prepare the master model or prototype to be duplicated, clean the surface thoroughly and fix it securely to avoid movement during pouring.
Step 2: Weigh the required quantity of liquid silicone accurately, add the matched curing agent according to the recommended proportion.
Step 3: Stir the silicone and curing agent mixture slowly and uniformly to ensure full integration, avoiding uneven curing or partial solidification.
Step 4: Pour the well-mixed silicone into the prepared mold frame steadily; the mold will fully cure and form within 2-3 hours at room temperature.
Application Scenarios
This high-performance mold making silicone is widely applied across multiple industrial fields: resin crafts, PU and unsaturated resin casting; gypsum, cement and concrete decorative components; candle crafts, lighting ornaments, plastic toys and stationery gifts; large Buddha statues, relief carvings and cultural artifact replication; furniture decoration, building materials and large cement molds; simulation landscapes, animal and plant sculptures, sandstone crafts, and product prototype design & development. It helps manufacturers improve production efficiency, maintain consistent casting quality, and reduce long-term production costs significantly.
