Most substrates are best prepared by cleaning with a 50:50 mixture of isopropyl alcohol (IPA) and water* prior to applying 3M Tapes. There are exceptions!

Exceptions to this general procedure that may require additional surface preparation include:

Heavy Oils: A degreaser or solvent-based cleaner may be required to remove heavy oil or grease from a surface and should be followed by cleaning with IPA/water.

3M tape,
You can maintain consistency from sketch to construction, eliminating distracting, visible fasteners, like screws and bolts. These high-strength, double-sided acrylic foam tapes let you quickly and easily create a long-lasting bond that actually builds strength over time.

Assemble the components of your extreme-action camera for impact resistance and durability. Rain, sun, wind, heat or cold, 3M™VHB™ Tape is weather-proven to stand the test of time.

Polyimide tape is made from a thermosetting polymer called polyimide. This material is resistant to chemicals, UV radiation, and high temperatures, making it an ideal choice for applications where other materials would break down or become damaged. The tape is typically available in a range of thicknesses and widths and can be customized to meet specific application requirements.
One of the most common applications for polyimide tape is in the electronics industry. It is often used as a protective covering for circuit boards and other components that are sensitive to heat. The tape can be applied directly to the component, acting as a barrier against heat and preventing damage to the device. Additionally, the electrical insulation properties of polyimide tape make it a popular choice for wire harnesses, transformers, and other electrical components.
