a resin polymerized from one of several sources: acrylonitrile, acrylic acid, methacrylic acid, etc.

a resin formed by reaction of polyhydric alcohols and polybasic salts. Saturated or unsaturated oils or fats are involved.

process where a special resin exchanges chloride or hydroxide for contaminant anions such as fluoride, nitrate, sulfate and bicarbonate. Water purification is the primary use.

ring compound materials in the oil composed of carbon, hydrogen, sulfur, nickel and other trace materials. Asphaltenes are mostly very small platelets (35 A) suspended by micelles of maltenes and resins and carried through the oil. They precipitate by agg

n: the procedure by which a quantity of resinous material is squeezed into a sandy formation to consolidate the sand and to prevent its flowing into the well. The resinous material hardens and creates a porous mass that permits oil to flow into the well but holds back the sand at the same time. See sand consolidation.

n: a thermosetting resin made from the by-product of the carbonisation of bituminous coal. It is used as a coating because of its adhesiveness, flexibility, and resistance to chemicals.

a chemical substance used to initiate the hardening reaction of a resin.

n: 1. any compound characterized by the presence of a reactive chemical structure that has an oxygen atom joined to each of two carbon atoms that are already bonded.2. any of various resins capable of forming tight cross-linked polymer structures characterized by toughness, strong adhesion, and high corrosion and chemical resistance. Epoxys are used extensively as coatings and adhesives.

a resin formed by reaction of polyols with epichlorohydrin.

an organic resin, formed by polymerization reaction of furfuryl, used in consolidation, zone shut-off and water control.

n: a powdered resin coating that forms a skin over pipe when applied to its heated steel surface. Usually applied at the mill.
