Surface Modification is the combination of physics and chemistry working together to modify materials to enhance surface properties. TriStar’s Surface Modification Division (SMD) has pioneered all new techniques to address your toughest surface challenges.
Our services include:
Application Technical Briefs
Surface modification can improve adhesion properties, micro-clean, functionalize (amine, hydroxyl, carboxyl, etc.), produce biocompatibility, create permanent moisture, and produce hydrophobic characteristics.
Surface Modification Benefits
Uniform 3-D treatment
Plasma treatments have the unique ability to treat a material three dimensionally.
Surface Chemistry control
A variety of surface treatment technologies are used to achieve the prescise results required for your application.
Long Treatment Lifetime
Surface modifications create a covalent bond between the polymer and the paint, ink, glue and/or coating.
High volumes can be attained via continuous, high throughput treatment of large rolls of material.

Plasma is a combination of physics and chemistry working together to modify materials and enhance the surface properties to better accept a secondary manufacturing application. TriStar uses an eco-friendly vacuum plasma process for a more consistent and longer-lasting surface and cleaning treatment. .
A corona discharge is plasma at standard atmospheric pressure. This plasma is produced by high voltage and the close proximity of two metal plates (electrodes) in atmosphere. When an electrical discharge occurs, ions and ozone are nearly always generated.
Parylene is the generic name used to describe a family of polymers based on polyxylene. It is a conformal coating applied in thin layers (typically a few mills or fractions of a mm) through dipping, spraying or simple flow coating.
Photolysis systems combine principles of corona and plasma. These systems use high voltage to excite gas in an emitter, which then radiates to the surface of a polymer. The radiation is then fine-tuned to chemically modify a polymer to receive most adhesives, paints, coatings, and inks.
