Water-Based Coatings

The first water-based coating contained styrene or styrene butadiene and was known as latex paint. These paints were for interior use only, but over the years, acrylic or acrylic ester resins were developed for exterior use. Other water-based paints are alkyds, vinyl or polyvinyl acetates and cement-based coatings.

Acrylic coatings are available as either opaque (colored) or clear. Methyl methacrylate is often used as a clear coating for concrete to provide weathering protection.

Water-based coatings have higher permeability to water vapor, making them suitable for application over moist, porous surfaces, such as wood, concrete, and masonry.

Solvent-Based Coatings

These coatings can be purchased as either clear or opaque materials. Clear solvent-based coatings use drying oils mixed with a resin and are generally referred to as varnishes. Various clear coatings will contain either:

  • Phenolics Present good water and weathering characteristics. When mixed with tung oil, these varnishes are most durable for marine use. However, the relative dark color tends to darken with age and might preclude its use in some areas.

  • Shellacs Shellac is a resin dissolved in spirit varnish, a volatile solvent. This coating is more often used as a sealer under a more-durable top coat.

  • Lacquers Cellulose derivations in volatile spirits. They have some application in interior use, particularly for aesthetic...

Products & Services
Architectural Coatings
Architectural coatings include paints, sealers, and specialty coatings for floors, roofs, walls, ceilings, decks, pavement, walkways, concrete surfaces, and other building and construction applications.
Industrial Coatings
Industrial coatings are thin films deposited upon materials to add or enhance desired properties, such as color, conductivity, corrosion resistance, etc.
Industrial Paints
Industrial paints are pigmented liquids or powders that are used to protect and/or beautify substrates.
Wall Coatings
Wall coatings are decorative or protective layers that are applied to a building’s interior or exterior walls. They are viscous enough to avoid running and provide abrasion and environmental resistance.
Radiation Curable Coatings
Radiation curable coatings are cured through exposure to ultraviolet (UV) light or electron beam (EB) irradiation. They provide rapid processing compared to film drying and thermosetting coatings.
