Frequently Asked Questions
What is a polyurethane adhesive?
Polyurethane adhesives, also known as PU adhesives, are created by dissolving urethane adducts in suitable solvents. Polyurethane compounds belong to the family of thermoplastics, as they are polymers that melt and flow when heated.
What is polyurethane adhesive used for?
Polyurethane adhesives can be used for a variety of applications and are suited to processes that involve forming, designing and sealing. It can be used in a range of industries to make manufacturing and construction processes cheaper and simpler. For example, polyurethane adhesives can be used for the following applications:
- rubber latex
- surface coatings
- conveyor belts
- paint compositions
- panel bonding
- home construction
- adhesive for footwear, textiles, packaging and automotive
- fabric coatings
What are the advantages of using polyurethane adhesives?
Polyurethane adhesives offer a range of advantages including:
- Great versatility for both interior and exterior applications
- Highly resistant to heat, water and chemicals
- Strong bonding properties
- Great flexibility
- Tear resistance
- Different colours can be added
TDI Based Adhesives
A two component, hydroxyl terminated polyurethane, which requires crosslinking with isocyanate to improve heat resistance. These are ideal for shoe manufacture and fabric lamination. Typical solvents are ketones, esters and THF.
MDI Based Adhesives
A one component adhesive, with good heat resistance and which may not require crosslinking. Typical solvents are ketones and THF.
The RE-ADD polyurethane adhesive range varies from soft slow crystallising grades to fast crystallising grades which
provide immediate high green strength.
These high performance adhesive raw materials provide outstanding flexibility, varying crystallisation rates and
excellent bond strength. Contact Townsend Chemicals to find out how they can improve your product.
