Frequently Asked Questions

What is the maximum temperature limit for Siltek® deactivated glass?

Maximum temperatures usually will be dictated by the composition of the glass, not by the surface treatment. The Siltek® layer is stable at temperatures up to 450°C, but some glasses can soften at lower temperatures. Injection port temperatures normally are well below the Siltek® maximum temperature limit, so Siltek® treatment is an excellent deactivation for all injection port surfaces.
