tesa 4432 – specialist sandblasting stencil masking and reinforcing tape

tesa® 4432 is a durable, professional masking tape with a strong and stabilized paper backing, coated with a natural rubber adhesive. Thanks to its high adhesive strength, tear resistance, and excellent dimensional stability, it is used wherever precision, durability, and mechanical resistance are required.

The tape was designed for producing stencils for sandblasting glass, mirrors, and stone, with resistance of 6 s / 4 bar, and for joining and strengthening surfaces. It can also be used as shatter protection – laminated to the back of mirrors – meeting the requirements of DIN EN 12600 for glass safety.

Thanks to its strong, smooth paper, tesa® 4432 excellently absorbs paint, ensuring clean paint edges, and allows for easy hand-tearability without the need for scissors. The product maintains its properties at temperatures up to 100°C, allowing safe use in technological processes requiring heating.
