Questions for application planning

How should a coating system be selected?

Start with the fiber structure, the role of each coating layer, the coating and curing process, and the properties that will be evaluated on the finished fiber.

Why should finished-fiber testing be included?

The coating operates as part of the fiber structure, so process compatibility and optical, mechanical and environmental behavior should be checked on finished fiber.

Can TIANZE support application evaluation?

Share the fiber structure, process conditions and target tests so the materials team can identify a suitable product and evaluation path.
