What kind of surfaces can the 3M™ Aluminum Foil Tape 427 stick to?
This tape has a pressure sensitive acrylic adhesive that sticks well to various types of substrates including smooth, rough or textured metal and painted surfaces.
Does this tape resist heat and cold temperatures?
Yes, it can withstand extreme temperatures ranging from -65°F (-54°C) to 300°F (149°C). It will remain intact under fluctuating weather conditions.
How durable is the tape against tears or punctures?
With its durable aluminum backing, this tape resists tearing and puncturing even in harsh industrial environments.
Is there any specific method for applying the foil tape onto a surface?
For best results, clean the surface before application and ensure there are no oils or dust particles present. Once adhered, press down firmly with consistent pressure using a plastic scraper tool to remove air bubbles underneath.
3M™ Aluminum Foil Tape 427 is a reliable solution for heat dissipation and substrate protection in high temperature environments. Its dead soft, thermally conductive aluminum backing reduces hot spots and ensures even heat distribution. This tape is a linered version of 3M™ Aluminum Foil Tape 425, making it ideal for die cutting applications. Its highly engineered acrylic adhesive can withstand exposure to high heat and humidity, providing a strong and reliable bond. It is also resistant to moisture, weathering, UV, and solvents, making it suitable for indoor and outdoor use.Recommended Applications
