Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a high-adhesion strong-bonding core product, specially developed for bonded components, composite structures and adhesion scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with adhesion promoters and bonding modifiers, featuring ultra-strong adhesion strength, good compatibility with multiple substrates, fine uniform closed-cell structure, good elasticity and adhesion stability. It has an adhesion strength of ≥1.5 MPa, strong bonding to metal, plastic, glass and other common substrates, no peeling, effectively ensuring bonding firmness, solving the problem of traditional foaming materials’ poor adhesion in bonding scenarios. Compatible with most of our bonding products, it is ideal for bonded components, adhesion buffers and composite structures.

How to Use
1. Clean the bonding substrate (metal, plastic, glass, etc.) to remove oil, dust and impurities (ensure good adhesion, avoid bonding failure).
2. Take Part A and Part B according to 1:1 weight ratio, stir separately to eliminate sediment, mix and stir thoroughly for 3 minutes until homogeneous.
3. Apply the mixture to the bonding surface, bond the two substrates, press gently to ensure no gaps, foam and cure at room temperature or by heating (heating helps enhance adhesion strength).
4. After full curing, test adhesion strength (≥1.5 MPa) to confirm no peeling, then use in bonding and composite scenarios.
