Solvent Bonding

Solvent bonding or solvent sealing is a process in which the surfaces of flexible materials are treated with a chemical solvent in order to form a permanent bond. The solvent temporarily softens the material and the bond is made by chemical reaction. As the solvent evaporates, the two surfaces firmly bond together.

How solvent bonding is used

Solvent bonding is often used for securing fill and vent tubes to closed chamber type constructions. It is used with amorphous polymers, such as polycarbonate, PVC and polystyrene. Higher molecular-weight polymers have better resistance to solvent-induced cracking, so using low molecular-weight polymers is not recommended.

Examples of sealing with solvents:

Insertion of a tube into a fitting for inflatable products
Joining surfaces made of dissimilar materials for more flexibility on material thicknesses and compositions such as: polyurethane to PVC and Hypalon to polyurethane, PVC, synthetic and natural rubbers, etc.
