A paint thinner is a solvent used to dilute oil-based paints [1] [2] or varnish. In this context, to dilute is also known as to 'thin'. Paint thinners are diluents. Solvents labeled "paint thinner" are usually white or mineral spirits.
The solvent also modifies the curing rate and viscosity of the paint in its liquid state. There are two types of paint: solvent-borne and water-borne paints. Solvent-borne paints use organic solvents as the primary vehicle carrying the solid components in a paint formulation, whereas water-borne paints use water as the continuous medium.
Wood is very porous and will absorb the solvent in paint and cause it to dry more quickly. This is undesirable because most paints undergo chemical reactions during the process of curing (for example, latex- and alkyd-based paints polymerise when curing) which is dependent on the water or solvent evaporating slowly. A layer of primer will ...
White spirit is the most widely used solvent in the paint industry. In households, white spirit is commonly used to clean paint brushes after use, to clean auto parts and tools, as a starting fluid for charcoal grills, to remove adhesive residue from non-porous surfaces, and many other common tasks.
Lacquer thinner, also known as cellulose thinner, is usually a mixture of solvents able to dissolve a number of different resins or plastics used in modern lacquer. [ 1 ] Previously, lacquer thinners frequently contained alkyl esters like butyl or amyl acetate , ketones like acetone or methyl ethyl ketone , aromatic hydrocarbons like toluene ...
The solvent condenses on the more frigid workpiece and the now liquid solvent dissolves the greases on the part. With the impurities contained in the liquid beads, the solvent runs off the part. Some systems are designed to capture and reclaim this solvent, making the process much more economical. Other adaptations to the simple system include:
