Primers and Adhesion PromotersMaster Bond manufactures a line of adhesion promoter primers for use with its adhesives on difficult to bond substrates. These include a primer specially formulated for polyolefin surfaces such as polyethylene and polypropylene. These primers are intended for use in conjunction with adhesives such as epoxies and silicones.

These primers improve surface wettability, inhibit corrosion, enhance bond strength and offer surface protection prior to bonding. They are often used to replace surface treatments and are capable of penetrating rough surfaces enabling effective sealing characteristics. Careful quality control procedures need to be strictly followed to ensure proper processing. Thickness of the primer is of vital importance. Additionally selecting the proper primer requires careful consultation with the adhesive formulator to ensure suitability with the adhesive/substrate combination and optimizing durability in service.
