Product Features & Advantages
This industrial casting silicone offers a wide hardness adjustment range to match different casting materials and mold sizes, with smooth fluidity that simplifies pouring operation and improves production efficiency. It boasts superior mechanical properties, especially high tear and tensile strength, and excellent flexibility for damage-free demolding even for complex patterns. With heat resistance, effective cut-growth resistance and minimal shrinkage, it supports hundreds of repeated use cycles, greatly extending mold service life and reducing long-term replacement costs. Diverse curing agent options allow flexible adjustment of working and curing time to fit different production schedules.
How to Use
Step 1: Prepare and clean the master model or prototype thoroughly, fix it firmly on a flat base to avoid displacement during silicone pouring.
Step 2: Weigh the required amount of liquid silicone accurately, add the matched curing agent according to the specified ratio.
Step 3: Stir the silicone and curing agent mixture slowly and evenly to ensure complete blending, preventing uneven curing and shortened mold life.
Step 4: Pour the mixed silicone steadily into the mold frame; the mold will cure fully and form in 2-3 hours at room temperature.
Application Scenarios
This high-performance mold making silicone is widely used in multiple fields: resin crafts, PU and unsaturated resin casting; gypsum, plaster, cement and concrete decoration; candle crafts, lighting ornaments, plastic toys and stationery gifts; large Buddha statues, reliefs and cultural relics replication; furniture decor, building materials and large cement molds; simulation landscapes, animal & plant sculptures, sandstone crafts and product prototype development. It helps manufacturers improve production efficiency, maintain stable casting quality and reduce overall operational costs.
