Requirements for adhesives
The footwear industry has very high requirements for the physical and chemical properties of adhesives. These properties mainly include initial adhesion (initial bonding strength), peel strength, creep resistance, heat resistance, cold resistance, open time (time for maintaining adhesion), tackiness, fatigue resistance, hydrolytic resistance, shelf life, yellowing resistance and aging resistance.
Adhesives commonly used in shoe-making industry
General-purpose chloroprene rubber adhesive
Generally used as a bonding agent for heel linings, edge sealing, lining materials, and interfacing.
Polyurethane solvent adhesive
Generally used as a bonding agent for the bottom.
SBS adhesive
Generally used as sole binding glue, hemming glue and lining glue.
Water-based chloroprene rubber adhesive
Generally used for bonding fabric together.
Water-based polyurethane adhesive
Generally used as a bonding agent for the bottom.
