Green Masking Tape Japanese Washi Paper Masking Tape Waterproof Acrylic Adhesive

Product Specification

1. Exceptional Thermal Stability
Key Advantage: Withstands prolonged high temperatures without failure

Technical Performance:
Resists continuous temperatures up to 120°C (premium grades: 180°C), far exceeding standard PVC tapes (80°C) or masking tapes (60°C).

Maintains adhesive integrity under heat:
Low-Tg (glass transition temperature) acrylic adhesives stay elastic, preventing hardening or cracking.

Backing materials (e.g., aramid fiber-reinforced paper) retain dimensional stability, avoiding shrinkage that causes paint bleed.

Application Example:
In automotive factory baking lines (120°C for 30 minutes), the tape stays securely bonded, whereas standard tapes delaminate or leave sticky residue on car bodies.

2. No Harmful Emissions or Contamination
Key Advantage: Safe for heat-sensitive environments

Technical Performance:
Made from solvent-free acrylic adhesives and eco-friendly paper, emitting ≤0.1ppm VOCs when heated (vs. PVC tapes releasing HCl gas).

Non-corrosive: Adhesives pass copper mirror test (ASTM D1248), ensuring no chemical reaction with metal substrates during high-temperature curing.

Application Example:
In aerospace coating processes, the tape prevents contamination of aircraft aluminum alloys, unlike cheap tapes that release sulfur compounds causing corrosion.

3. Precise Masking with Heat Resistance
Key Advantage: Maintains sharp paint edges under heat

Technical Performance:
Ultra-thin profile (0.05–0.1mm) conforms to microstructures (e.g., 0.5mm gaps between engine parts).

Heat-resistant edge stability:
Backing paper has ≤5% thermal expansion coefficient (vs. 15% for standard paper), keeping masking lines accurate even after 2 hours at 120°C.

Application Example:
When painting turbine blades (requiring 0.2mm precision), the tape’s edge remains fixed, while standard tapes expand and cause overspray, leading to costly rework.

4. Easy Removal Without Residue
Key Advantage: Clean release after high-temperature exposure

Technical Performance:
Adhesives feature a balanced tack-adhesion ratio:
High initial tack (10N/25mm) ensures immediate bonding to hot surfaces (e.g., 80°C preheated metal).

Low final adhesion (≤3N/25mm after cooling) allows peel-off without tools, even after 72 hours at 120°C.

Application Example:
In industrial oven painting, the tape peels off in one piece from 100°C surfaces, while competitor tapes fragment, requiring solvent cleaning that delays production.

5. UV & Chemical Resistance for Extended Use
Key Advantage: Multi-environmental durability in high-heat settings

Technical Performance:
Passes QUV-A UV test (1000 hours, equivalent to 5 years outdoors) with ≤5% color change and 0% adhesive degradation.
Resists common solvents used in pre-paint cleaning, maintaining integrity during degreasing of hot components (e.g., 60°C engine parts).

Application Example:
For outdoor machinery painted in summer (40°C+ with UV), the tape stays effective for 30 days, whereas standard tapes degrade in 3 days, causing paint leaks.

6. Versatility Across High-Temperature Substrates
Key Advantage: Bonds to diverse hot surfaces

Substrate Compatibility:
Metals: Preheated steel (100°C), anodized aluminum, stainless steel.

Plastics: Heat-resistant polymers (e.g., PEEK, PSU) at 120°C.
Composites: Carbon fiber components during autoclave curing (130°C, 8 bar pressure).

Application Example:
In motorcycle exhaust pipe painting (surface temp: 90°C), the tape adheres securely to the hot chrome surface, while standard tapes melt and fail.

7. Time & Cost Efficiency
Key Advantage: Reduces rework and material waste

ROI Breakdown:
Labor savings: 30% faster masking due to tearability (no scissors needed for 50°C surfaces).

Rework reduction: 85% fewer touch-ups vs. standard tapes (data from automotive OEMs).

Material waste: 95% clean peel-off reduces solvent usage for residue removal.
