Tesa 04342-00000-00 Copper 4342 Precision Mask Masking Tape 19mm x 50 m

This masking tape is a paper-backed adhesive product designed for controlled masking and heat-exposed operations. It combines a paper substrate with an acrylic adhesive and is intended for use where precise edge definition and thermal durability are required.

• Acrylic adhesive delivers 1.5 N/cm peel force for secure temporary bonding
• Backing paper provides 85 μm overall thickness for clean edge performance
• Tensile strength of 32 N/cm resists tearing during application
• Withstands continuous exposure up to 150°C for heat-applied processes
• Available in copper colour for high-visibility masking control

• Suitable for automotive paint masking tasks requiring heat resistance
• Ideal for fine-line paint separation during multi-stage coatings
• Used for industrial masking where visibility of the tape is necessary
• Can be used in thermal curing processes at elevated temperatures
• Appropriate for precision masking on assemblies needing controlled adhesion

The adhesive maintains temporary bond strength and allows clean removal when used within the stated maximum operating temperature.

The paper backing provides a defined edge and reduces seepage, helping achieve precise paint lines.

The copper colour enhances contrast against substrates, assisting accurate placement and inspection.

Higher tensile strength reduces the risk of elongation or tearing while applying long runs or pulling across contours.
