What is an aqueous coating?
What is Aqueous Coating? Aqueous coating is a water-based, environmentally friendly coating that dries quickly when applied to printed materials. This coating is clear, but also has the capability to create a satin, soft-touch or glossy finish.
What is the difference between varnish and aqueous coating?
Aqueous coatings provide more substantial scuff-resistance than varnishes. Aqueous is typically applied to the entire printed piece, usually by the last unit on a printing press. Due to its water base, aqueous coating is more environmentally friendly than varnish or UV coatings.
What is aqueous coating on business cards?
What is an Aqueous Coating? It’s also referred to as AQ coating. It’s a clear coating that’s a fast-drying coating used to help prevent the cards from getting damaged while protecting from fingerprints, smudges, dirt, and scratches.
How is aqueous coating applied?
The Aqueous Coating Process Machines apply aqueous coating immediately before printing ink on sheets. After the application, the sheet passes through a heated air system for quick-drying, and then makes its way to the finishing section of the facility.
What does aqueous coating look like?
Aqueous coating is a clear, fast-drying water-based coating that is used to protect printed pieces. It provides a high-gloss, satin, or soft touch finish. Because it is water-based, aqueous coating is more environmentally friendly than varnish or UV coatings.
What is non aqueous coating?
AF-COAT (Non Aqueous) are a unique concept of film coating material of a solvent base ( organic solvent) and it is a dry dispersion of white and also available in all colors and shade or customaries colors or as per customers requirement. It is used for coating of tablets, pills , pallets, and also granules .
What is the difference between varnish and coating?
What’s the difference between coating and varnish? Aqueous coatings are among the most commonly used coatings. They provide better rub protection than varnish and increase durability of the printed piece. These low-cost, clear, water-based vegetable cellulose coatings are applied to the sheet after the ink.
What is the difference between coating and varnish?
What is the function of coating?
Traditionally, the primary functions of coatings are to protect and decorate substrates. More recently, growth has occurred in the research and development, as well as commercialisation, of coatings which have novel functions in addition to having traditional protection and decoration properties.
Why film coating is done?
Film coating is a common step in tablet manufacture that can be used to improve product appearance, organoleptic properties, or to facilitate swallowing. Functional film coats can also be used as a part of the product’s stabilisation strategy and to modify or delay drug release.
What is the difference between UV and varnish?
UV gives more protection and sheen than either varnish or aqueous and, since it is cured with light and not heat, no solvents are emitted. You can coat 80-pound text and heavier, although cover weights are preferred. UV can be used on smooth papers only.
What is the principle of coating process?
Coating process: – The basic principle of tablet coating is simple. Tablet coating is an application of coating composition to a moving bed of tablets with the concurrent use of heated air to facilitate evaporation of the solvent.
Is UV coating water-based?
Water-based UV coatings are an industry breakthrough. This technology allows us to match or create any custom color, without limitations to shade. This allows for more color and coating options for our clients. Water-based UV coatings are also excellent when it comes to coverage and light stability.
Why coating is required?
They prevent corrosion. Rust or other corrosive debris is another issue that often pops up in industrial applications. Often the materials that are hard enough to actually build machinery from are also very likely to corrode over time.
What is coating machine used for?
Tablet coating machines are used to coat the surface of tablets with a thin coating of film. The film is employed mostly to: mask the colour, taste and smell of the drug. protect the drug from physical or chemical harm.
How is UV coating applied?
UV Coating is applied in liquid form, then exposed to Ultra-Violet light which bonds and dries it instantly… hence its name “UV Coating.” It can be applied over the entire printed piece (called Flooding) or it can be used as a Spot coating to just highlight particular areas.
