Instant grab hybrid structural adhesive saves days

A two-part hybrid technology structural adhesive from 3M can save significant time when bonding bigHead and general fasteners.

Scotch-Weld Epoxy-Acrylic Hybrid Structural Adhesive 7271 B/A has been designed to secure this type of fasteners instantly and is suitable for a wide variety of substrates including composites, GRP, epoxy-based resins, aluminium and stainless steel.

Dispensed using the Scotch-Weld EPX system, the adhesive can be applied with a manual or pneumatic hand-held applicator, saving days compared with the hand lay-up techniques used previously.

Imran Idrees of 3M's Industrial Adhesives & Tapes Division commented: "7271 B/A can instantly hold mechanical fixings unlike commonly used two-part acrylic adhesives which can take anything up to three hours to hold fixtures. "Moreover, when compared with pungent, basic entry-level acrylic adhesives this instant grab adhesive is odourless. This eliminates the need for a respirator to protect against odour during use, and can be applied vertically or even upside down without the adhesive dripping." The biggest cost and time savings are for applications where numerous fixtures need to be bonded.
