-
Can I be sure that my rust problem will disappear when using this tape on my ductwork?
: Although we see major success with our customers minimizing corrosion damage or completely aiding in preventing any through using our weld bonding adhesives paired with VCI films specifically catered to corrosion reduction on metals -- Our Aluminum Foil Tape can lay atop slight blemishes such as surface rust being only minimally effective when directly applied onto dirty metal containing existing oil from maintenance practices or glues if not cleaned before use.
3M™ Aluminum Foil Tape 427 is made up of a thermally conductive aluminum backing that is dead soft. This backing helps to dissipate heat over the surface of the tape, reducing hot spots and protecting the substrate from the effects of high temperatures. This tape is a linered version of 3M™ Aluminum Foil Tape 425, which makes it suitable for die cutting applications. It is coated with a highly engineered acrylic adhesive that can withstand exposure to high heat and humidity while maintaining a strong and reliable bond. This tape can withstand a variety of moisture, weathering, UV, and solvents, making it an excellent choice for indoor or outdoor use.
