High Quality Durable & Fast Shipping PU Coating Silicone Keypad

PU coated silicone keyboard, also known as oil silicone keyboard, is designed with a protective oil layer to enhance durability and protect symbols and characters from wear and tear.  The oil coating provides a pleasing texture and matte smooth surface to printed icons and graphics, ensuring longevity and a professional finish.  This coating is typically used on keyboards with screen-printed characters and symbols, while laser-etched silicone keyboards are often PU-coated for extra protection.

Surface protection options for rubber keyboards:

1. PU (polyurethane) coating: Provides solid protection and superior durability compared to oil coatings, ensuring long-lasting performance.
2. Epoxy coating: Contains a transparent resin layer that provides a clear and visually appealing finish to the rubber keyboard.
3. Plastic keycaps: Provide a high level of protection, but are more expensive to produce due to molding requirements.
4. Oil coating: An economical option for keyboard manufacturing, but not as durable as PU or epoxy coating.

Surface treatment:

– Oil coating and PU coating create a matte surface, providing a smooth touch.

– Epoxy coating provides a clear, glossy surface that enhances the keyboard’s visual appeal.

These protective layers are designed to extend the life of your keyboard, preserve surface icons or graphics, and maintain the vibrant colors of your silicone buttons.

Silicone buttons are classified according to conductivity:

Silicone rubber keyboards differ not only in their surface finish, but also in their conductive mechanisms.  It can be divided into four types according to its conduction method:

1. Carbon pill silicone keyboard: Carbon pills are used under the rubber buttons, which have reliable conductivity and long service life.
2. Conductive ink silicone buttons: Use conductive ink to achieve efficient conduction and provide a cost-effective solution.
3. Gold Pill Silicone Keyboard: Made of Gold Pill, which has low resistance conductivity and is suitable for precise and high-performance applications.
4. Metal dome rubber keyboard: Utilizes metal dome to achieve conductivity, provide tactile feedback and excellent durability.

Each type of conductive silicone keyboard is selected based on specific resistance requirements, and carbon pellet keyboards are known for their low resistance and longer life compared to conductive ink keyboards.
