3M Sealants & Adhesives
3M™ SCOTCH-WELD™ STRUCTURAL ADHESIVES
Using 3M™ Scotch-Weld™ structural adhesives in place of mechanical fasteners gives you more design flexibility and provides many benefits to your production process.
There are four main adhesive chemistries suitable for replacing traditional joining methods. Acrylic adhesives are best used for bonding metal and plastics while providing high-impact resistance. Epoxy adhesives are the most flexible, offering superior vibration and environmental resistance compared to other chemistries. Urethanes offer quick cure speeds and are best for bonding dissimilar materials. Cyanoacrylate instant adhesives bond to the widest range of substrates, come in a variety of viscosities and have the fastest cure speeds.
When choosing your adhesive there are many factors to consider such as what substrates are being bonded, cure speed desired, type of joint, stresses, and how the adhesive will be applied.

Orabond Primer
ORABOND® UHB PrimerB
The ORABOND® UHBPrimerB improves adhesion to thermoplastic elastomers (TPE), polyolefins (TPO) and EPDM. It is a ready-to-use primer, diluted with xylene and is particularly suitable for use with double-sided adhesive tapes, such as the ORABOND® UHB series. The added fluorescent dye helps to ensure uniform adhesion promoter coverage.
