Pyrosil® is a silicate-coating treatment, administered via flame, applied to low surface energy substrates to improve ink adhesion.
Technical Explanation:
The PYROSIL® Process is based on the flame-pyrolytic deposition of amorphous silicon dioxide on a substrate material, and thus a type of silicate coating. The surface to be treated will be fed through a gas flame which is doped with a silicon-containing precursor material (PYROSIL®). The PYROSIL®, also referred to as the precursor, burns in the flame and deposits on the surface in a very thin but dense and firmly adhering silicon oxide coating (5 – 100 nm). Due to the short flame-substrate interaction the material's surface temperature remains moderate.
In Laymen's Terms:
Pyrosil is transferred to a substrate via flame. This attaches microscopic particles of Pyrosil (a silicate compound) to the substrate, creating a nanoscale roughness that makes the surface high energy and allowing the ink to adhere more strongly. Because the substrate does not need to be exposed to the flame for an extended period of time, Pyrosil can be used on less temperature-resistant materials, such as plastic.
Applications
Pyrosil applications and applicators range from small, manually handled products to large-scale, automated production. It can be applied to a variety of products, from glass and plastic bottles to aluminum bodied automobiles.
