Adhesives And Joining Technologies

Adhesives and joining technologies are also known as binding technology. Adhesives are substances like glue, mucilage which is used to bind two surfaces to resist their separation. They might be found naturally or synthetically .For an adhesive to work effectively, it must have three properties, it must be able to wet the surface; it must harden and finally must be able to transmit locals between the two surfaces being adhered. However it can be problematic for low energy materials such as polymers. To solve this problem, surface treatment can be used to increase the surface energy as a preparation step before adhesive binding.
