Bonding & Substrates

Bonding

Generally all plain metal sheets and metal laminates are bonded to various substrates by contact cements, by rigid glues or even double sided adhesive tapes. With the great variety of metal alloys and substrates, specifiers should inquire about the chemical and mechanical suitability of any bonding process in relation to any substrate, metal alloy and intended usage load.

Substrates

All metal laminates should be bonded to medium or high density fiberboard, high quality particle board or plywood of sufficient thickness. The quality of the substrate will promote better adherence and flatness. Sheet metal and metal laminates can be bonded to flat sheet metal substructures such as elevator doors. Do not specify drywall, gypsum, concrete, solid lumber or underlayment as substrate for bonding sheet metal and metal laminates.
