Key Features & Functions

Specialized Adhesive Layer for Metal Plates

Phosphate-ester modified acrylic adhesive, providing chemical bonding with the metal oxide layer.
Differential Double-Sided Design

High-tack on one side (Metal side: > 15N/25mm); Medium-tack on the other (Fire-rated board side: 8-12 N/25mm).
Specialized Adhesive Layer for Fire-Rated Boards

Tackifying resin compound system, engineered to penetrate the micropores of melamine surfaces.
Hygrothermal Durability

Bonding retention rate > 80% after 1,000 hours under 85° C / 85% RH conditions.
Scratch Resistance

Surface hardness up to 3H (Pencil Hardness).
Anti-Fingerprint (AF)

Fluorosilane surface treatment with a contact angle > 110°.

Laser Cutting Guidance

Infrared-absorbing marking layer ensuring a cutting precision of +/-0.3mm.
Thermal Compression Compatibility

Capable of withstanding thermal bonding processes at 180° C for 30 minutes. UV Curing Adaptability: Light transmittance > 90% at the 365nm wavelength.
Self-Healing

Thermal recovery function for minor scratches (< 10um) at 60° C for 5 minutes.
Chemical Resistance

Resistant to acids and alkalis (pH 3–11) and solvents (ethanol and acetone rub resistance).
Stamping Positioning

Microporous air-release grid to prevent bubbling during the stamping process.
