The Universal Selection Source: Adhesives Ingredients

Polyurethane Adhesive
Polyurethane Adhesives are known for toughness and flexibility even at low temperatures. They have fairly good shear strength and excellent water and humidity resistance. One-component polyurethane adhesives consist of isocyanate-containing prepolymers dissolved in a solvent carrier while two-component polyurethanes consist of a polyol component (resin) and an isocyanate component (hardener). Polyurethane adhesives form strong bonds to rubber, plastics, metal, wood, paper, ceramic, and fabrics. Two-component polyurethanes are used for large-surface adhesive bonds, like in in vehicle superstructures.

Thermoplastics Polyurethanes Adhesives (TPU): Techno Brief

By SpecialChem

This guide contains significant information regarding thermoplastic polyurethanes (TPUs) for the adhesives and sealants industry. TPUs are formed by linear polymeric chains comprising a small proportion of hard segments and soft segments. Should you work with TPU this guide would prove to be a worthy source of TPU technology in adhesives and industrial applications that have been exploiting its benefits and performance characteristics.

Polyurethane Dispersions (PUD) Selection

By Edward M. Petrie

This guide will endeavor to direct the formulator through the process of selecting polyurethane dispersions for a specific adhesive formulation and end-use requirement. The chemistry of the polyurethane dispersion will dictate the performance properties. Therefore, the formulator needs to know what properties are affected by certain characteristics of the dispersion.
