FAQ
Common questions about this material family.
What is the difference between EK-D03, EK-D08 and EK-D14?
The grades differ in temperature range and application profile — exact values are in each product TDS. Send your operating conditions and we will recommend a grade.
Can I test the material before committing to volume?
Yes — sample support is available for qualified B2B projects after a short technical review.
Which substrates are compatible?
Steel, stainless and other metals are typical. Compatibility for a specific substrate is confirmed per grade in the TDS.
How is this different from conventional high-temperature paint?
Silazane-derived coatings convert to a dense ceramic layer, designed for service beyond the range of conventional organic paints. Comparative data is available on request.
What is the minimum order quantity?
MOQ depends on the product and packaging format — to be confirmed with our team for your grade.

About organic polysilazane resins
These resins are supplied as liquids or solids and are used both directly — as binders, varnishes and impregnation media — and as precursors that convert to SiCN, SiCNO and SiO2 ceramics on curing. Grade choice follows the target chemistry, viscosity and cure route.
Typical evaluation starts with the substrate, operating temperature and application process. Exact temperature limits, film thickness and curing parameters depend on the product grade and are confirmed in the TDS. Sample support is available for qualified B2B projects.
