What Are Commercial Coatings & Adhesives?
Commercial coatings & adhesives are used to bond with different types of surfaces to deliver a desired quality for enhancing safety, visual appeal, or functionality. Some commercial coatings & adhesives such as paints not only offer decorative qualities, but also protect the substrate from harm. Functional coverings are an option for changing surface characteristics to provide a unique quality like adhesion or wear resistance. Paints, for example, are used on industrial pipes to prevent corrosion and some coatings provide additional traction for safety purposes. They may be used to cover the entire substrate or only a portion and come in a variety of forms including:
- Slip Resistant
- Photoluminescent
- Pressure Sensitive
- Tapes
- Non-Stick
- Reflective
- Anti-Scratch
- Anti-Corrosion
- Conversion Coating – Designed for metal substrates where an electro-chemical or chemical procedure is used to make the part surface into a coating. This process is often chosen for adding properties such as corrosion protection or greater surface hardness.
- Knife Over Roll – Coating is passed into a gap between a knife and support roller to ensure that both the covering material and substrate pass through as excess materials are scraped off. It is a good choice for high viscosity coats or high coat weights.
- Meyer Rod – The coat is deposited on the substrate as it runs through a bath roller. The Meyer Rod ensures the right quantity remains on the substrate, which is determined from the diameter of the used wire.
- Saturation Coating – The substrate is dipped into a bath at a low viscosity thus allowing the excess to run back into the bath when pulled. It is a method that is often used for porous substrates.
