ADHESIVES for POLYOLEFIN

Polyolefin is a thermoplastic, that is, it is one of a variety of materials that have the property of becoming hard and rigid when cooled and are moldable when heated. Polyolefins soften or fuse when heated and harden and become rigid again when cooled without undergoing any appreciable chemical change. Polyolefin comes in many different chemical formulae (due to additives) with differing chemical and mechanical properties, including adhesion, and varying thicknesses -- both of which affect its coefficient of expansion. Successful long term bonding of polyolefin to itself and to other substrates, requires careful preparation and matching of the adhesive being used with the differing COEs of the substrates involved. BONDiTTM products are among the few available that can be used to bond polyolefin to substrates with other COE's for harsh environments and long term deployment without debonding.

Our highest recommended product for bonding polyolefin is BONDiTTM B-45TH or B-482TH or B-4682 depending upon the relative need for chemical resistance, bond strength, impact and vibration resistance, heat resistance, and COE differential.

Our recommendation would change if a fast cure is needed, in which case we recommend the use of BONDITTM B-536TH.

Other recommended products are hot melts BONDiTTM HM-502 or HM-505 with adhesion promoter, BONDiTTM A-43.

Among the other substrates to which polyolefins can be bonded using BONDiTTM products are:
UHMW, Delrin, fluoropolymers, rubber, polyethylene, polyolefins, polypropylene, polyurethane, silicone, thermoplastics, thermoset, urethane, ceramics, glass, fiberglass, wood, metals, stone, aggregate and concrete.
