Product Features & Advantages

1. Excellent heat stability, resisting aging, cracking and deformation in high-temperature heavy industrial casting;

2. Full deep curing without thickness limit, suitable for super-thick heavy industrial casting molds;

3. FDA-certified non-toxic formula, compliant with multi-scene industrial safety standards;

4. High fluidity liquid silicone for full perfusion of complex heavy mold structures without dead angles;

5. High tensile and anti-tear strength, resisting heavy pressure and repeated demolding;

6. Stronger environmental adaptability than ordinary industrial Mold Silicone rubber;

7. Customizable curing time, hardness and color for personalized heavy industrial casting demands.

Step-by-Step Operation Guide

1. Mix heat stable silicone A and B components evenly at 1:1 weight ratio for 2-3 minutes;

2. Perform 2-5 minutes vacuum defoaming to eliminate bubbles and ensure mold structural stability;

3. Pour liquid RTV mold silicone into heavy industrial casting molds steadily;

4. Select room temperature curing or high-temperature fast curing per industrial production needs;

5. Demold gently after full curing to complete heavy industrial casting production;

6. Seal residual silicone and store indoors, avoiding sun exposure and rain erosion.

Application Scenarios & Buyer Value
