Flexible Backing Conforms to Duct Piping Systems
3M™ ASJ Facing Tape 2C105 is a 7.5 mil, tri-directional reinforced tape that excels in demanding temperature and humidity applications. It is comprised of a kraft/scrim/foil laminated backing coated with a cold weather acrylic adhesive. The backing is flexible and conforms to irregular surfaces and curves. It features excellent performance in a range of temperature applications. Mold inhibiting agents help prevent the build-up of mold in the adhesive caused by humid and damp conditions.
3M™ ASJ Facing Tape 2C105 is UL 723 Classified (15/10 Flame/Smoke Rating). This facing meets ASTM1136, Type I, II, III and IV.
Recommended Applications
- Closure system on traditional all service jacket (ASJ) faced duct piping systems
- Vapor seal on traditional ASJ faced ductboard and pipe insulation
Cold Weather Performance
3M™ ASJ Facing Tape 2C105 is coated with a proprietary, pressure sensitive solvent acrylic adhesive specifically designed for cold weather applications, though this adhesive performs well at normal and high temperatures as well. With a service temperature ranging from -40°F/-40°C to 240°F/116°C, this tape can be applied in a variety of environmental conditions. This adhesive features quick stick at normal temperatures and excellent low temperature performance. Once bonded, it will provide good holding power for extended periods with good aging properties that resist lifting and curling.
Efficient Long-Term Installation
3M™ ASJ Facing Tape 2C105 applies easily to various types of thermal insulation, and is easily installed without special tools or application methods. The ASJ facing is conformable for consistent application even when applied to irregular surfaces or around curves. It is also tri-directionally reinforced, helping ensure that the material stays in place even when subjected to high shear loads.
The Science of Better Adhesion from 3M
Since 1925 when one of our lab assistants invented masking tape, 3M has been applying science to life – developing adhesive products and technologies that help entire industries and individual businesses worldwide. The work that began with a single 3M engineer now spans decades and generations. And all of it goes into each of our industrial tapes and adhesives, like 3M™ ASJ Facing Tape 2C105, to help businesses like yours operate faster, better and more efficiently.
