Bonding Dissimilar Substrates<\/h2>\n

It goes without saying that if you are bonding plastics use a plastic adhesive and if your bonding metal, an adhesive for metal.\u00a0 It gets more complicated when you want to choose industrial adhesives to join dissimilar substrates.<\/p>\n

Plastic to Metal Industrial Adhesives<\/h2>\n

Two HUGE categories here \u2013 there are likely an infinite number of combinations of plastic to metal.\u00a0 Some plastics easily bond, while others require specialty adhesives.\u00a0 Most metals are readily bonded provided the surface isn\u2019t oxidized (think rust and corrosion.)\u00a0 So let\u2019s go worst case scenario here and pick a tough to bond plastic and a tough to bond metal.<\/p>\n

Difficult to bond Plastic<\/h3>\n

PTFE (also known as Teflon\u00ae and polytetrafluoroethylene) is one of the most difficult to bond plastics. The coefficient of friction is the 3rd<\/sup> lowest known.\u00a0 As slippery as it is, it is used to line containers, coat processing equipment, and for slides to protect piping and other metals.<\/p>\n

Difficult to bond Metal<\/h3>\n

Again a variety of adhesives readily bond most metals. Stainless steel is relatively easy to bond, but depending on the surface condition.\u00a0 Mirror finish stainless steel can have very low surface energy and provide difficult.\u00a0 Automated means of abrading the surface can generate heat which might cause a surface change decreasing the adhesion of adhesives to the stainless steel.<\/p>\n

If treatment is needed to obtain a high strength bond to mirror finish stainless steel, sand blasting is recommended to roughen up the surface without generating heat.<\/p>\n

PTFE to Stainless Steel Adhesive Options<\/h3>\n

\"industrial<\/p>\n

In this scenario, there are few adhesives that offer any adhesion to PTFE.\u00a0 Options include either a cyanoacrylate along with POP primer or a structural acrylic like Permabond TA4610 or.<\/p>\n

Generally, if a designer chose SS and PTFE \u2013 the item likely needs to resist abrasion, impact, chemicals, temperature, etc.\u2026<\/p>\n

Standard cyanoacrylates are brittle and have low impact resistance.\u00a0 They have good resistance to non-polar solvents and withstand 180F.\u00a0 Bond strength on<\/p>\n

Permabond structural acrylics like TA4610<\/a> have good adhesion to PTFE with no primer needed.\u00a0 They also bond stainless steel (over 1000 psi shear strength). Standard epoxies will have double that strength to stainless but virtually no strength on PTFE.\u00a0 In the following image, PTFE bonded with TA4610 stretches and ultimately fails before the bond.<\/p>\n

Bonding dissimilar substrates can be challenging but with a good understanding of what the industrial adhesives bond needs to withstand it is generally possible.\u00a0 Questions about bonding dissimilar materials \u2013 contact Permabond for a recommendation.<\/p>\n
