Polyurethanes (PUR) have many advantages and form the basis for many top quality adhesives and sealants. We offer a varied choice of products which covers many applications used throughout industry. Polyurethane technology aids good performance levels on many materials including some exotic woods (we advise checking this out first before using polyurethane wood glue due to the high presence of natural oils) and plastics though again take care with polyethylene's, polypropylenes and low energy surfaces including Silicones.
Use our 3M Structural Adhesives Selector Guide to help you find the most suitable product for your application.
However when you do require high strength but low stiffness (e.g. plastics to metals), where combinations of mismatch materials are subject to natural differential expansions, then polyurethane adhesives & Sealants do 'fit the bill'.
Ideal for bonding & sealing plastics especially polycarbonates and acrylics, and for painted/coated metals, composites, wood, & concrete. Good for temperature and moisture resistance too as well as flexibility. So throw away the screws - Polyurethane adhesives ought to be your first consideration and aesthetically can be very presentable too.
