Spray Adhesive for Sponge

Spray adhesive‘s core bonding mechanism relies on "physical penetration"—seeping into the microscopic pores of soft, porous materials (like sponges, fabrics, and leather backs) to form thousands of microscopic "anchor points" (essentially "growing" inside the material). Conversely, smooth, hard surfaces like phone cases and rubber outsoles lack these pores, causing the adhesive to float on top and fail instantly. Every adhesive has its specific purpose; it only delivers true value when used in the right application.

A Brief History of Spray Adhesive

Furniture spray adhesive is indispensable for bonding foam, fabric, and leather in sofas and mattresses. Modern eco-friendly versions feature low odor and strong adhesion, boosting efficiency in soft furniture manufacturing. Factories now use machine spraying for uniform application and material savings. For homes, small cans serve as a practical tool for repairing cushions and refurbishing old furniture.
