A substrate is a material to which adhesives bond with. Any material that an adhesive is used on is referred to as a substrate. This includes metals, plastics, ceramics, textile and other kinds of materials. Different manufacturing industries are trying to find materials that are strong but light, fast and inexpensive to produce. This resulted to new substrates that many traditional adhesives simply do not work on.
New adhesives had to be developed to cope with the new substrates. Among the newer products are various types of polyurethane adhesives which are able to bond with various kinds of substrates. The polyurethane adhesives has revolutionized manufacturing processes. It has also helped companies who are working on adapting more eco-friendly methods.
Polyurethane adhesives have faster curing time and ability to cure different application conditions such as those with high moisture. These adhesives are also water proof. It also has a very strong bonding capability. In automotive applications, rivets and polyurethane adhesives are used for locking structure instead of the traditional nuts and bolts. Combine this with its ability to be used on aluminum and other light materials and the result is a lighter and more fuel efficient automobile.
The same benefits are experienced in the manufacture of food packages. The result are lighter food packaging which makes transport easier and also lowering the cost.
The new substrates are opening opportunities for better quality and eco-friendly products and processes. The modern adhesives allow companies to take advantage of these opportunities.
