25*25mm Yellow Matte Wood-Plastic Composite Right-Angle Moldings

Key Advantages

• Matte surface characteristics: 60° gloss ≤8 GU (per GB/T 9754) with diffused reflection ≥85%, producing minimal glare under direct lighting. Fingerprint retention approximately 70% lower than glossy surfaces.
• Color stability: With added color masterbatch and UV stabilizers, color difference ΔE changes at ≤0.2/Year under indoor lighting (illuminance ≤500 lux). After 500 hours xenon arc aging, ΔE ≤3.
• Biological resistance: Internal porosity ≤2.5% Limits moisture retention for termite or mold growth. ASTM G21 mold test shows no growth after 28 days.
• Crack resistance: 500g steel ball dropped from 500mm at -10°C produces no cracking or fracture. Vicat softening temperature ≥65°C prevents softening under summer heat.
• Dimensional precision: Angle tolerance 90° ± 0.5°, Leg length tolerance ±0.2mm, straightness ≤1.2mm/m. Joint height difference ≤0.3mm across multiple pieces.

Frequently Asked Questions and Precautions

Q: Does the matte surface become glossy (polishing effect) after long-term use?
A: In high-traffic areas (hallway corners, door edges), after approximately 20,000–30,000 wiping or friction cycles, 60° gloss may increase to 10–15 GU. Periodic light sanding with fine matte sponge along the length direction can partially restore the matte effect.

Q: Will the yellow color fade under direct sunlight?
A: UV stabilizers are added to the formulation. Under indirect indoor light, color stability is maintained for 5–8 years. For direct sunlight areas (near windows or glass curtain walls), apply a UV-absorbing clear topcoat or inspect color difference every 2–3 years.

Q: Can this profile be heat-bent for curved applications?
A: WPC becomes moderately bendable when heated to 120°C–140°C. Use a heat gun with uniform heating. Minimum bending radius ≥30cm. Do not repeatedly bend after cooling, as whitening or cracking may occur.

Q: How to repair surface scratches?
A: Light scratches (depth ≤0.2mm): sand gently along the length with 400–600 grit sandpaper and wipe with a soft cloth. Deep scratches are difficult to repair on-site; Cut and replace the damaged section with a 45° scarf joint.

Precautions

Clean substrate with alcohol or neutral cleaner to remove oil and mold release agents before installation. Substrate flatness requirement ≤2mm over 2m length.

Use fine-tooth saw blades (≥60 teeth) for cutting. Chamfer cut ends 0.5mm with 200-grit sandpaper to prevent edge chipping during installation.

For kitchen or grease-prone areas, clean quarterly with neutral degreaser and soft cloth to prevent uneven gloss from oil film formation on the matte surface.

Avoid direct contact with polyurethane foam adhesives, as solvents may soften the WPC surface. Recommend MS polymer or neutral silicone adhesives.

Store horizontally in dry, cool areas away from direct sunlight. Stack height ≤1.2M to prevent bending. Protect from sunlight to avoid surface yellowing.

Avoid water exposure or high humidity (RH >85%) within 24 hours after installation to ensure complete adhesive curing.
