Waterborne polyurethane dispersions for high-performance adhesives

Adhesive manufacturers are changing to waterborne alternatives because of their improved environmental profile and high performance. Waterborne raw materials are more sustainable, with comparable performance, than solventborne materials.

Key properties of adhesives based on our waterborne polyurethane dispersions include:

· Excellent initial bond strength

· Rapid bond strength development

· High final bond strength (including substrates that are difficult to bond, e.g. PVC)

· Good thermal resistance

· Good resistance against humidity, oil and chemicals

· Considerable formulating freedom and the ability to tailor properties for specific applications
