Polyurethanes are one-component thermoplastic systems in solvents
often containing catalysts in small amounts to introduce a degree of thermosetting properties. They are also available as two-part thermosetting products in liquid form, with or without solvents,second part is a hardener.

Polyurethane adhesives make good adhesives for a number of reasons:

1. They effectively wet the surface of most substrates.
2. They can interact with the substrate through polar interactions.
3. Through molecular composition the adhesive stiffness, elasticity and crosslinking can be tailored to suit specific needs.

The adhesive solutions are applied to both surfaces to be bonded. Some time is allowed for the solvents to evaporate and the surfaces are then pressed together, at which point inter-diffusion of the polymer chains will occur.

Based on their outstanding properties polyurethane adhesive have found broad use in many application areas The segments in which polyurethane adhesives are used most are:footwear industry, construction , woodworking, transportation, packing and assembly operations.

Polyurethane (PU) Shoe Adhesive, It has strong initial strenght, good heat-resistance, uneasy to form fine thread, short tack time,suitable for both handwork etc.
