Water-based lacquers are used extensively in wood furniture finishing as well. One drawback of water-based lacquer is that it has a tendency to be highly reactive to other fresh finishes such as quick-dry primer (excluding waterborne lacquer primers), caulking and even some paints that have a paint/primer aspect.
Most coatings have four basic components. These are the resin, solvent, pigment and additive systems [5] but the resin or binder is the key ingredient. Continuing environmental legislation in many countries along with geopolitics such as oil production are ensuring that chemists are increasingly turning to waterborne technology for paint/coatings and since resins or binders are the most ...
Water-based paints tend to be the easiest to clean up after use; the brushes and rollers can be cleaned with soap and water. Proper disposal of left over paint is a challenge. Sometimes it can be recycled: Old paint may be usable for a primer coat or an intermediate coat, and paints of similar chemistry can be mixed to make a larger amount of a ...
Chalk paint is a water-based, decorative paint invented by Annie Sloan which may be applied over almost any surface. It requires very little preparation and needs a topcoat to avoid flaking. Chalk paints are also used by utility companies to mark road surfaces.
The word lacquer refers to quick-drying, solvent-based varnishes or paints. Although their names may be similarly derived, lacquer is not the same as shellac and is not dissolved in alcohol. Lacquer is dissolved in lacquer thinner, which is a highly flammable solvent typically containing butyl acetate and xylene or toluene.
Shellac is an odour and stain blocker and so is often used as the base of "all-purpose" primers. Although its durability against abrasives and many common solvents is not very good, shellac provides an excellent barrier against water vapour penetration. Shellac-based primers are an effective sealant to control odours associated with fire damage ...
The best known lacquer, an urushiol-based lacquer common in East Asia, is obtained from the dried sap of Toxicodendron vernicifluum. Other types of lacquers are processed from a variety of plants and insects. The traditions of lacquer work in Southeast Asia, South Asia and the Americas are also ancient and
At midrange (between short paste and long paste) water miscible oil paint is gouache-like, sharing the properties of both transparent watercolor and opaque oil (in the manner of watercolor, for example, some colors will darken upon drying, the more so as more water is mixed into the paint, and in the manner of oil, the paint film will have some ...
