Durable High Quality Fast Ship PU Coating Silicone Keypad

PU Coating Silicone Keyboards, also referred to as oil silicone keypads, feature an oil coating that serves as a protective layer for the rubber surface. This coating enhances durability by safeguarding symbols and characters from abrasion, scratches, and general wear. Applied after printing icons or graphics, the oil coating ensures longevity.

These rubber keypads with oil cover offer a pleasing texture, leaving the surface of silicone rubber keypads matte and smooth. Oil coating is commonly employed in keypads with silkscreen printed characters and symbols, while laser etched silicone keypads are typically PU coated.

Surface Protection Options for Rubber Keypads

– PU (Polyurethane) Coating:Provides solid protection, offering enhanced durability compared to oil coating.

– Epoxy Coating:Features a transparent resin layer, giving rubber keypads a clear and attractive appearance.

– Plastic Keycaps:Offer robust protection but come with higher production costs due to molding requirements.

– Oil Coating:Economical option for keypad manufacturing, though not as durable as PU or epoxy coating.

Surface Finishes:

– Oil coating and PU coating result in matte surfaces.

– Epoxy coating provides a clear and glossy finish.

These protective layers aim to prolong keypad lifespan, preserve surface icons or graphics, and maintain silicone button colors.

Types of Silicone Keypads Based on Conductivity

Silicone rubber keypads vary not only in surface finish but also in their conductive mechanisms. They can be classified into four types based on their conduction methods:

  1. Carbon Pill Silicone Keypad

– Features carbon pills beneath the rubber buttons for conductivity.

  1. Conductive Ink Silicone Keypad

– Utilizes conductive ink for electrical conduction.

  1. Golden Pill Silicone Keyboard

– Incorporates gold pills for low resistance conductivity, suitable for precise applications.

  1. Metal Dome Rubber Keyboard

– Utilizes metal domes for conductivity, offering tactile feedback and durability.

Each type of conductive silicone keypad is chosen based on specific resistance requirements, with carbon pill keypads being notable for their low resistance and long service life compared to conductive ink keypads.
