P&R Keytops – Injection molded plastic keytops are compression molded onto the key top. The keytops can be colour molded to suit a case/product design. A scratch resistant hard clear coating can also be applied to the keytop surface.
Epoxy Keytops – Depositing an epoxy coating on the top surface of the key provides a more resilient key surface. This is not recommended for outdoor applications due to lower UV resistant .
Polyurethane Coatings – Polyurethane also known as a PU coating, is a wear resistant clear spray that is applied to provide added chemical and wear resistance to painted surfaces, which can be in either a matt or gloss finish. PU coatings provide a longer switch face life with a silk-smooth texture.
Testing Silicone Rubber Keys
To ensure full functionality and long-life, the wear resistance is tested using an RCA machine, for abrasion performance and resistance to wear in accordance with international test standards. For further information download our Silicone Rubber Keypad Design guide below. Design Guide
