What are polyurethane (PU) coatings?

Polyurethane (PU) coatings are high-performance protective finishes primarily used for wooden surfaces such as doors, furniture, cabinets, and flooring. These coatings provide a hard, durable, and smooth finish that enhances the natural beauty and lifespan of wood. PU coatings offer: 1. Excellent scratch and abrasion resistance 2. High durability 3. Smooth glossy, semi-gloss, or matte finish options 4. Protection against moisture and stains Traditionally, PU coatings were oil-based, but modern water-based PU finishes are now widely available. Water-based options offer lower odor, faster drying time, and are more environmentally friendly while maintaining strong protection and aesthetic appeal.
