Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a hydrophobic water-repellent core product, specially developed for water-proof, water-repellent and humid environments. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with hydrophobic additives and water-repellent modifiers, featuring strong hydrophobicity, water repellency, fine uniform closed-cell structure, good elasticity and water stability. It has a water contact angle of ≥110°, no water absorption, no water penetration, effectively repelling water and preventing water damage, solving the problem of traditional foaming materials’ water absorption in humid scenarios. Compatible with most of our industrial and construction products, it is ideal for water-proof components, water-repellent buffers and humid environment scenarios.
