HTP has taken on the task to develop specific liquid resists for etching various metals. As a result of the focussed development, in close cooperation with our customers, products are offered, which are widely recognized by the PCM industry.

The photoresists allow to apply the same processing conditions for copper, aluminium, brass and stainless steel. Eventhough the products are fully aqueous processable, they offer higher resolution capabilities and equal adhesion compared to solvent processable materials.
