I Holland’s PharmaCote® range is a suite of treatments and coatings that enhance the performance of substrate material for punches and dies. Since the introduction of our first coating in 2007 I Holland has carried out extensive research into anti-stick, abrasion resistance, and corrosion protection so you guarantee longer-lasting tools.
