ATTENTION! MADE TO ORDER - NO RETURNS POSSIBLE - PLEASE MAKE A THOUGHTFUL PURCHASE

tesa® 4831 is a professional, silicone-free masking tape designed for the most demanding industrial applications. Made with a PET/polypropylene backing and coated with an acrylic adhesive, it provides excellent high-temperature resistance (up to 180 °C) and clean, precise edges after painting. Due to its silicone-free composition, it does not contaminate surfaces, allowing for seamless subsequent production steps – such as bonding, varnishing, or powder coating.

Technical specifications:

• Tape type: technical masking
• Backing: PET/polypropylene film (silicone-free)
• Adhesive: acrylic, high-temperature resistant
• Colour: white
• Temperature resistance: up to +180 °C
• Resistance: to chemicals, aging, and high temperature
• Adhesive residue: none – clean removal after the process

Application:

tesa® 4831 tape was developed for specialized industrial applications, including:

• surface protection before assembly processes, e.g., window bonding,
• fastening and protection of composite elements and layered metal structures,
