Protection and Durability Advantages: Dual Protection for Extended Keypad Lifespan

The epoxy layer acts as a 'protective film' on the surfaces of the printed layer and silicone rubber substrate. It significantly enhances the key’s resistance to wear and tear, addressing the issues of easily worn printing and prone-to-contamination surfaces' in traditional silicone keys.

• Wear Resistance: Prevents printed layer peeling, ensuring long-lasting clear markings
  Purely printed silicone keys often have surface characters that become worn and blurred due to daily pressing, finger friction, or cleaning wipes. In contrast, the epoxy layer has high hardness and strong friction resistance. It fully covers the printed layer, isolating the pattern from direct external friction. Even with long-term, high-frequency use, the printed characters remain clear, avoiding the problem of 'unrecognizable markings.'
  
• Corrosion and Stain Resistance: Easy-to-clean surface for complex environments
  The surface of the epoxy layer is smooth and hydrophobic, making it less likely to absorb contaminants such as dust, oil, and sweat. During daily use, oil stains and water droplets only stay on the surface of the potting adhesive and can be easily wiped clean with a damp cloth. Additionally, the epoxy layer is resistant to acids, alkalis, and alcohol, making it suitable for scenarios like kitchen appliances, medical equipment, and bathroom devices. This prevents the silicone substrate or printed layer from aging or discoloring due to chemical corrosion.
  
• Aging Resistance: Slows silicone oxidation for improved overall durability
  The epoxy layer blocks direct contact between ultraviolet rays, ozone, and the silicone substrate, slowing down the silicone’s aging process , such as preventing yellowing, hardening, and reduced elasticity of the silicone. At the same time, the epoxy has strong adhesion to silicone rubber, so issues like 'cracking or delamination of the epoxy' do not occur during long-term use. The overall lifespan of the keys can be extended by 30% to 50% compared to printed silicone keys without epoxy.
