2/10/2024 0 Comments White wood stainWhile dyes are molecules that dissolve into the vehicle, pigments are larger than molecules and are temporarily suspended in the vehicle, usually settling out over time. The difference between the two is in the solubility and in the size of the particles. Pigments and/or dyes are largely used as colourants in most stains. However, because the binders are from the same class of film-forming binders that are used in paints and varnishes, some build-up of film occurs. In principle, stains do not provide a durable surface coating or film. Transparent varnishes or surface films are applied afterwards. Much like the dyeing or staining of fabric, wood stain is designed to add colour to the substrate (wood and other materials) while leaving some of the substrate still visible. Stain is composed of the same three primary ingredients as paint (pigment, solvent (or vehicle), and binder) but is predominantly vehicle, then pigment and/or dye, and lastly a small amount of binder. Coloured or stained finishes do not typically deeply penetrate the pores of the wood and may largely disappear when the finish deteriorates or is removed. The vehicle often may be water, alcohol, a petroleum distillate, or a finishing agent such as shellac, lacquer, varnish and polyurethane. Vehicle is the preferred term, as the contents of a stain may not be truly dissolved in the vehicle, but rather suspended, and thus the vehicle may not be a true solvent. It consists of colourants dissolved and/or suspended in a vehicle or solvent. Wood stain is a type of paint used to colour wood. The initial application of any paint or varnish is absorbed into the substrate similarly to stains, but the binder from a stain resides mainly below the surface while the pigment remains near the top or at the surface. Wood stain is a type of paint used to colour wood comprising colourants dissolved and/or suspended in a vehicle or solvent.
