Surface Coating Options for Silicone Keypads:
- Polyurethane (PU) Coating
A highly durable and flexible finish that offers superior resistance to abrasion, chemicals, and UV exposure, ensuring long-term protection with a smooth, glossy appearance.
- Matte Smooth Coating
This non-reflective coating creates a sleek, smooth surface that minimizes glare while offering a soft-touch feel. It also resists fingerprints and stains, maintaining a high-quality aesthetic.
- Epoxy Coating
A tough, resilient coating known for its exceptional adhesion, chemical resistance, and long-lasting durability. It delivers a glossy, smooth finish capable of withstanding demanding applications and environmental conditions.
- Laser Silicone Coating
An advanced coating technique that enhances tactile response and durability. Using precision laser technology, this method etches custom patterns on the surface, combining functionality with visual appeal.
