Improving Anti-stick Properties

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 PharmaCote® CN in 2007 I Holland has carried out extensive research (both academic and in the field) into anti-stick coating solutions using many forms of advanced technology such as Atomic Force Microscopy (AFM); scanning electron microscopy; laser profilometry; adhesion mapping; x-ray photoelectron spectroscopy; raman spectroscopy and time of flight secondary-ion mass spectrometry. In addition, work on abrasion resistance is continuing including nanowear testing to simulate wear caused by abrasive granules on punch tip surfaces.

 

Our focus is on providing the best customer service possible by furthering tabletting science and developing solutions that help to enhance the performance of our punches and dies, extending product life and increasing yield for our customers. I Holland PharmaCote® products offer solutions for sticking, corrosion, pitting and abrasion.

 

Due to the many varying parameters in tablet production, including environmental conditions and differences in compounds to be compressed, the performance of these coatings can vary from application to application. As part of I Holland’s commitment to customer service our experienced technical staff will offer up to date information and assistance when selecting an appropriate PharmaCote® product for your tooling.

TSAR≈PREDICT

What does it do?

TSAR PREDICT forecasts the best anti-stick PharmaCote® coating solution for your formulation. It calculates single particle adhesion to the punch tip face without time consuming and expensive field trials.

Who is it aimed at?

Any tablet manufacturer experiencing sticking problems including pharmaceutical, nutraceutical, industrial, confectionery, veterinary applications.

What does it cost?

TSAR PREDICT is a free of charge service available to all I Holland customers.

What information does I Holland need from me?

All we need from you is the name of the API or main component of the formulation. Even if this API is confidential we can work with basic characteristic information on key physical properties.

About TSAR

The TSAR PREDICT service is the culmination of two years’ research in association with the University of Nottingham to investigate the root causes of why formulations stick to tablet tooling surfaces. It takes into account the interactions between various parameters such as Van der Waals Forces; capillary action and deformation mechanics. This research has been a key part of I Holland’s Tabletting Science Programme.
