Adhesives for Bonding Polyolefin Substrates

Polyolefins are very difficult to bond on account of their non-polar, non-porous and chemically inert surfaces. In order to meet the needs of plastic companies, Master Bond has developed adhesives to bond polyolefin substrates without surface pretreatment. These systems are convenient to apply, feature long-term durability and save time and energy.

Traditional Approach to Bonding Polyolefins

The high degree of chemical inertness found in polyolefins generally limits the usefulness of solvent bonding as a viable assembly technique. One successful approach to adhesive bonding of these materials involves proper surface pretreatment prior to bonding. The pretreatments which are widely accepted include chemical etching, flame treatments, corona discharge and gas plasma. Following any one of these surface pretreatments, an appropriate epoxy, polyurethane, silicone or other adhesive system can be used depending on the type of service environment the adhesive would be exposed to.
