Technical Information
Manufactured from BAKEWELL silicone rubber, the 8mm silicone cap is ideal for masking during electro-static powder coating, stove enamelling, E-Coat, plating and anodising. The high temperature resistance means they can be re-used over and over. When used as rubber caps, the 8mm silicone cap is simply pushed over the stud or pin requiring masking. As a plug, it is often best to push the Silicone Rubber caps into the hole to be masked, using a radiused end insertion tool, or on larger sizes, the end of a pencil or pen. After processing, the Silicone Rubber cap is simply removed, while the component is still hot. Any coating build up can be removed manually, or in a rumbler. Popular sizes are colour coded to assist in selection and identification. The table shows the range available and what parts best suit the threads to be masked.
