What are the challenges of achieving a high-gloss finish on WPC sculptures?
Achieving a high-gloss finish on Wood-Plastic Composite (WPC) sculptures presents several unique challenges. First, the porous nature of WPC materials can lead to uneven absorption of coatings, resulting in patchy or dull surfaces. Proper surface preparation, such as sanding and sealing, is critical but time-consuming.
Second, WPC's thermoplastic properties make it sensitive to heat during polishing, potentially causing warping or melting. Selecting compatible coatings—like UV-resistant polyurethane—is essential for durability without compromising aesthetics.
Lastly, environmental factors like humidity can affect adhesion and curing, requiring controlled conditions. Mastering these challenges ensures a flawless, long-lasting glossy finish on WPC sculptures.
