Keral 99 TF

Thin-layer substrates

When we talk about reliable and economical quality thin film, we talk about K99TF. Due to the unique formula and selection of raw materials, our R&D department has created a substrate material that exhibits reliable quality and high performance, while remaining at a comparable price. The smooth surface, strength and dimensional accuracy are huge advantages when it comes to dealing with new thin-film designs, or even replacing other available properties.
