Understanding the Scotch® ATG System
Scotch® ATG system has proven to be the go-to adhesive solution since the early 1970s. For light and heavy industrial applications, the Scotch® ATG Adhesive Applicators are convenient, reliable, versatile tools capable of attaching a wide range of materials. With no cure time, the adhesive instantly bonds long, large and small surfaces. As a portable, hand-held solution, it can apply tape to any shape or form, even from an uncomfortable position, while allowing your free hand to hold the part.
With Scotch® ATG Applicators, a touch of the finger triggers a quick, controlled application of Scotch® ATG Transfer Tape at the same time as the liner rewinds into the applicator. There is no mess and no cleanup. 3M advanced acrylic adhesive bonds on contact and is formulated with a choice of properties including high temperature resistance, acid free, general purpose and high initial adhesion.
The ATG system is a cost effective and more productive replacement to many double-sided tapes, tape applicators, as well as adhesive dots, staples and liquid adhesives. This applicator allows the ATG liner to rewind into the applicator as the adhesive is applied for hassle-free operation that eliminates messes and clean-up.
