TPU Adhesives for Shoes

Features:

Good adhesion to a variety of substrates - TPU, Nylon, PVC, Leather, Synthetic Leather, Polyester, Fabrics,etc.

Application:

Shoe Industry, Textile Industry and others.

Processing Method:

By Solvent. The formulation we generally suggested is one-third (1/3) each of MEK, Acetone and Toluene. In general, it depends on the customer's requirement. If you require the faster volatility, you can use more Actone. If you would like to reduce the cost by Toluene, the Max. Toluene in Solvent is 30% ~ 35%. If the Toluene is not allowed, you can use EAC instead. As to the actual formulation, it should be adopted according to the characteristics of solvent and every customer's needs.
