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 ...
Release agents may be water or solvent-based and use of either will depend on the personal preference of the molder, plant safety regulations, hazardous materials shipping costs, state, local, or federal regulations, and/or desired drying times of the release coating. Water-based die lubricant (WBD) has been used for about 40 years. All die ...
Polyurethane dispersion, or PUD, is understood to be a polyurethane polymer resin dispersed in water, rather than a solvent, although some cosolvent may be used.Its manufacture involves the synthesis of polyurethanes having carboxylic acid functionality or nonionic hydrophiles like PEG (polyethylene glycol) incorporated into, or pendant from, the polymer backbone.

Commercial rust converters are water-based and contain two primary active ingredients: tannic acid [1] and an organic polymer.Tannic acid chemically converts the reddish iron oxides into bluish-black ferric tannate, a more stable material. [2]
A paint thinner is a diluent solvent used to dilute oil-based paints or varnish. [1] [2] In this context, to dilute is also known as to 'thin'. 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.
Polyacrylate emulsion, water-borne coating, are used as binder for outdoor and indoor "latex" house paints.; Acrylic paints as artist paints.; Acrylic fibre.; Sodium polyacrylate water-soluble thickeners, a polymer for the production of the Superabsorbent polymer (SAP) used in disposable diapers due to its high absorbency per unit mass.
Solvent degreasing is a process used to prepare a part for further operations such as electroplating or painting. Typically it uses petroleum , chlorine , dry ice or alcohol based solvents to dissolve the machining fluids and other contaminants that might be on the part.
