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
- Pressure Sensitive
Commercial coatings & adhesives may be used to provide one or more of these qualities to enhance a product or improve safety. For example, adding a slip resistance adhesive to the rails of a vehicle enhances the guard rail and offers a safety feature. The most important consideration when evaluating commercial coatings & adhesives is the application process that will be used. This is because it determines the ability to control thickness and in some cases a process will not be feasible for meeting certain needs.
The Different Types of Coating Processes
Various commercial coating & adhesive processes can be used to add the desired qualities. Among these are vapor deposition, chemical techniques, spraying, and roll-to-roll procedures. Certain application methods are better suited for a substrate and coating; however, the following are common in numerous commercial applications:
- 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.
The chosen application method varies depending on many factors including the substrate, desired end results, and the type of covering. Common commercial coatings & adhesives for the above application methods include: acrylic pressure sensitive, rubber pressure sensitive, low or high temperature heat solvent, primers, polyurethane, latex, and custom saturation coats.
