MACTAC: Nitrile-Phenolic Tapes

April 8, 2010
This company has refined its nitrile-phenolic tapes to provide significantly higher performance, meeting the needs of the new, higher-performing automotive transmissions now being manufactured.

For more than 25 years, MACtac® Specialty Products has offered a dry film alternative to liquid nitrile-phenolic adhesives, providing OEMs and automotive aftermarket manufacturers a solution that offers permanent adhesion, excellent chemical resistance, and the ability to withstand both high and low operating temperatures for applications like the assembly of friction materials. After extensive automotive testing, MACtac recently refined its nitrile-phenolic tapes to provide significantly higher performance, meeting the needs of the new, higher-performing transmissions now being manufactured.

The new-and-improved dry adhesives are an excellent alternative to liquid solvent-based adhesives, as they have fewer environmental and safety issues and can improve manufacturing efficiency while reducing waste. MACtac’s nitrile-phenolic tapes are very low in volatile organic compounds (VOCs) and do not experience the solvent evaporation and adhesive quality issues that can occur with liquid adhesives. Parts can be assembled more quickly and with little waste, as pre-measured tapes can be applied in-line to raw materials or converted parts using modest heat-assisted lamination. The thermoset adhesive bonds in minutes, with no extended cure time needed.

MACtac’s nitrile-phenolic dry adhesive tapes are available in a 1.0-mil tape (IF4020A) and a 2.0-mil tape (IF4022A), both featuring a 60# coated release liner for easy assembly and transfer to mating surfaces. With heat and pressure, the nitrile-phenolic adhesive quickly forms a very high bond to a variety of wet-laid fibers (paper), carbon, and other friction materials utilized in automotive OEM, heavy equipment, lawn and garden, and industrial applications.
