Adhesive

The adhesion of the resin matrix to the fibre reinforcement or to a base material in a sandwich situation-construction are important. Polyester resins generally have the lowest adhesive properties.Vinylester resin has improved adhesive properties over polyester but epoxy systems offer the bestchoice , and are therefore frequently found in many high-strength adhesives. This is due to their chemical composition and the presence of polar hydroxyl and ether groups. As epoxies cure with low shrinkage the various surface contacts set up between the liquid resin and the adherends are not disturbed during the cure. The adhesive properties of epoxy are especially useful in the construction of laminates where the small bonding surface area means that maximum adhesion is required.

Adhesive plays an important role in building industry. From fixing skirting boards to more

complex jobs , it always helps finish the job without traditional fixing such as nails and screws.
