Core Performance Advantages
First：
Excellent Impact Resistance With a moderate thickness of 0.38mm and high-strength film backing, it withstands high-speed impact from sandblasting, shot peening and glass bead blasting, resisting puncture and breakage to ensure stable shielding performance.
Second:
Good Conformability & Strong Adhesion The rubber-based adhesive delivers high adhesion. The tape features excellent elasticity and ductility, and fits tightly on complex workpiece surfaces such as curves, steps and corners, without lifting or peeling off during operation.
Third:
Clean Removal & No Adhesive Residue The specially formulated adhesive system is compatible with metal substrate surfaces. It peels off cleanly with no adhesive residue after processing, eliminating the need for secondary cleaning and ensuring the bonding strength of subsequent thermal spray coatings.
Fourth:
Versatile Light Shielding Performance The black backing provides good light shielding capability, which can also serve as light barrier and anti-splash protection in laser surfacing and laser surface treatment processes, realizing multiple functions with one material.
Fifth:
Convenient Application & Easy Slitting The wide master roll can be slit to any required width within the specified range, and can also be die-cut into special shapes as needed, adapting to fast construction of workpieces with different sizes and shapes.
First:
Thermal spraying pre-treatment masking: Precision shielding of non-spraying areas during sandblasting and shot peening roughening processes before plasma and HVOF spraying
Second：
Laser processing protection: Light shielding and anti-splash protection for non-processing areas during laser surfacing and laser surface treatment
Third:
Metal surface treatment: Selective protection of precision parts and machined surfaces during rust removal and shot blasting of steel structures and mechanical parts
Fourth:
General industrial protection: Local masking during surface blasting of textile machinery, auto parts and hardware, adapting to various surface treatment working conditions
Custom width slitting:
Precision slitting to any width within the 1250mm roll width according to customer requirements, adapting to different workpiece construction sizes
Custom die-cut shapes:
