Coatings and inks
Chempilots has extensive experience in formulating custom solvent-, UV- and water-based inks, coatings, and adhesives for medical device applications.
Polymer solubility and Hansen Solubility Parameters (HSP)
Our primary tool in formulation is Hansen Solubility Parameters (HSP), where Chempilots has developed proprietary software tools to find combinations of polymeric binders, pigments and solvents that form homogenously soluble or dispersible systems. From this, an initial shortlist can be further refined to fit a desired surface tension and evaporation profile in combination with minimized environmental exposures.
Use of HSP and our other solvent databases (1000+ solvents) turns formulation into a structured working process instead of a frustrating trial and error exercise.

Polymer coating properties
For medical device applications, the important dried-film properties are typically adhesion, cohesion, flexibility, abrasion resistance, wettability, film defects (pin holes, blisters, wrinkling, etc.), biocompatibility, leachables, stability and permeability (water, oxygen, APIs) in combination with any desired additional custom functionality. Chempilots has experience in formulating for these properties and the methods used for characterization.
Processing properties
Formulating for processing usually involves obtaining a stable, homogeneous mixture in combination with a rheology fitted to the method of application - printing, dipping, spraying, etc., as well as proper spreading, leveling, and drying kinetics.
APIs, pigments, fillers, additives
Chempilots has all dispersing, mixing, and milling equipment for development and pilot production of inks and highly filled polymer composites. We also have experience with filler treatment and selection of suitable additives.
UV inks, coatings, and adhesives
UV inks and coatings pose special requirements as formulations are closely tied to the desired product application and processing. Chempilots has a wide range of UV lamps from glass fiber spot curing to fusion lamps for development of UV formulation and processing solutions.
