Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a high adhesion core product, specially developed for multi-substrate bonding, sealing and composite scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with high-adhesion modifiers, featuring ultra-high adhesion strength, broad substrate compatibility, fine uniform closed-cell structure, good elasticity and adhesion stability. It can firmly bond to metal (aluminum, steel), plastic (PC, ABS), glass, ceramic and other common substrates, adhesion strength ≥1.5 MPa, no additional adhesive needed, effectively solving the problem of traditional foaming silicone’s poor adhesion and limited substrate compatibility. Compatible with most of our industrial and precision products, it is ideal for multi-substrate bonding, composite components and sealing scenarios.

5. Easy Operation: 1:1 simple mixing ratio, good flowability, easy to bond and foam, no professional adhesion operation skills required, improving production efficiency.
How to Use
1. Clean the substrate surface (metal, plastic, etc.) to remove oil, dust and impurities, ensure surface dry and clean (avoid affecting adhesion performance).
2. Take Part A and Part B according to 1:1 weight ratio, stir separately to eliminate sediment, then mix and stir thoroughly for 2-3 minutes until homogeneous.
3. Apply the mixture to the substrate surface, bond the target components, then foam and cure at room temperature or by heating.
4. After full curing, the product forms a firm bond with the substrate, no delamination, ready for use in bonding and sealing scenarios.
Application Scenarios
Focus on multi-substrate bonding scenarios: Metal-plastic composite components (paired with industrial mold silicone rubber), glass-ceramic bonding (paired with high-precision mold silicone), electronic component bonding (paired with Electronic Potting Compound), multi-material robot parts (paired with robot silicone), and industrial multi-substrate sealing (paired with industrial mold silicone rubber). It helps bonding-industry buyers simplify production processes and reduce costs.
Certifications and Compliance
