Double-sided UV-coated PC Hollow Sheet

1. Product Definition

Double-sided UV-coated PC Hollow Sheets are polycarbonate hollow sheet with a co-extruded UV-resistant protective layer applied to both sides.

2. Comparison: Double-sided VS Single-sided UV Coating

3. Production Technology & UV Coating Data

3.1 Core Co-extrusion Patent Technology

Adopts innovative UV+PC+UV double-sided composite co-extrusion mold design. Compared with traditional single-sided (UV+PC) production, the distributor composite structure cuts UV absorber consumption by 30%.
Production flow: PC raw material melting → UV raw material melting → multi-layer distribution fusion → sheet extrusion molding.

3.2 UV Coating Thickness Test Data

Thickness can be customized

4. Complete Product Specifications

Suitable for all PC hollow sheet series, all colors customizable.

5. Product Core Features

1. 1. Raw Material Safety: Made of pure polycarbonate resin; shatterproof, formaldehyde-free, non-flammable and safe to use.
2. 2. Ultra Weather Resistance: Stable performance under extreme high & low temperature; transparent surface will not fade after long-term outdoor use.
3. 3. Hollow Sandwich Structure Advantage: Good heat insulation & thermal retention; lightweight material, easy installation, high cost performance.
4. 4. Double-sided Full UV Blocking: Uniform UV coating on both surfaces, effectively isolate ultraviolet rays and delay aging.

6. Application Fields

1. 1. Building Outdoor Engineering: Roof daylighting, rainproof entrance canopy, eave shelter, smoke exhaust window, greenhouse panels
2. 2. Indoor Decoration & Furniture: Cabinet door panels, partition screens, lower door sheets, shop display backboards & shelf boards
3. 3. Commercial & Other Products: Partition wall panels, double-layer window sheets, lamp covers, advertising billboards, exhibition display sheets

7. Operation Guidelines: Installation, Storage, Maintenance & Safety Warnings

7.1 Installation Standard

1. 1. Screw Fixing
   • • Wrong operation: Screw tightly attached to plate without expansion washer; screw inserted obliquely into sheet; over-tightened screws by electric screwdriver.
   • • Correct operation: Match expansion washer to reserve thermal expansion gap; screw vertically into the plate; control screwdriver torque to avoid over-tightening.
2. 2. Thermal Expansion Hole Design
   Drill hole diameter should be 20%–30% larger than screw diameter to reserve expansion space for thermal expansion and contraction of PC material.
3. 3. Cutting Requirements
   Available cutting tools: Fixed/portable circular saw with hardwood blade, short-tooth jigsaw with universal blade.
   Slow feeding during cutting; prevent cutting dust from entering hollow cavities of the sheet.

7.2 Storage & Transportation Rules

• • Keep packages flat during storage and transit.
• • Avoid direct sunlight and rain soaking.
• • Do not peel surface protective film before installation to prevent scratches.

7.3 Cleaning & Maintenance Rules

• • Strictly forbid organic solvent cleaning.
• • Wipe with soft cloth + clean water; diluted neutral detergent is allowed for stubborn stains.

7.4 Safety Precautions

1. 1. Forbidden to use under open flame or ambient temperature above 120°C.
2. 2. Keep protective film intact until construction is fully finished.
3. 3. Long-term outdoor direct sunlight may cause sheet deformation and discoloration.
4. 4. Do not stack heavy goods on sheet surface.
5. 5. All cut panels must be fully fixed; foam buffer pads are recommended for protection.
