Polyurethanes are ideal for many bonding applications, including the bonding of composite materials, plastics, leather and more in the automotive industry. Products with a long working life are available, allowing them to be used on large bonding and potting surfaces. These products are characterised by low shrinkage (making them ideal for bonding thin ‘coats’ onto metal or laminate without any visible lines underneath). Permabond polyurethanes are available with different curing times to meet processing requirements. The products are available with pot lives ranging from 1 to 15 minutes. The black colour is suitable for black leather, carbon fibre and rubber.
The advantages of Permabond polyurethanes include:
- Different curing times
- Adhesion to a variety of substrates
- No priming is required
- Good tensile strength
- Easy to apply
- Elastic ties
