Tesa 4657 4657 Duct Tape, Grey, Acrylic Coated Finish

This duct tape is a cloth-backed adhesive tape intended for demanding industrial environments where heat tolerance and mechanical strength are required. It combines a coated fabric backing with a natural rubber adhesive and an acrylic-coated finish to perform under elevated temperatures and mechanical load. The product conforms to recognised standards and is presented in a NEUTRAL grey for discreet use.

• 180°C maximum operating temperature enables high-heat applications
• 105N/cm tensile strength resists tearing under load
• 4.6N/cm adhesion strength provides robust surface bonding
• 0.29mm thickness delivers durable, low-bulk reinforcement
• 7.5% elongation offers controlled elasticity for contouring

• Suitable for sealing heat-exposed ductwork joints
• Ideal for temporary high-temperature insulation repairs
• Used with cable bundles requiring flame-tolerant wrap
• Can be used for protective covering during thermal processes
• Useful for general industrial maintenance and patching

The backing is acrylic-coated cloth which gives dimensional stability and a textured surface that aids tear control and manual application.

A natural rubber adhesive is used, offering strong initial tack and effective adhesion to a variety of substrates.

The acrylic-coated finish improves surface durability and resistance to surface contamination during use.

It meets DIN EN
