What is ion exchange resin used for?
Ion exchange resin has been an effective water treatment tool for many years. The most common use by a long way is for water softening. Ion exchange resins, however, have many other less frequently used applications. Resins are used to reduce arsenic, nitrates, uranium, perchlorate, and more.
What is a composite resin tooth treatment?
The treatment involves removing some of the surface enamel to make the composite resin bond better with your tooth or teeth. It’s also for this reason that it’s discouraged for you to put in fillings repeatedly on the same tooth because it gets drilled over and over until the cavity widens too big for the filling to stick.
Can resin treatments improve well completion?
In addition to resin treatments applied during a well’s production phase, resin treatments have been successfully used as part of well completion strategies to improve conformance during the subsequent oil recovery production phase of the well’s later life. The use of resins for water control dates back at least to 1922.
What does resin do in water treatment?
The treatment of water using resins changes the physical chemistry of water and is able to remove dissolved solids, salts and ions. There are two general types of ion exchange resins: those that exchange positive ions, called cation resins, and those that exchange negative ions, called anion resins.

Does resin on teeth stain?
Composite resin is especially prone to developing stains from highly pigmented beverages like coffee or red wine. Over time, this may give the restoration a brown or red tint. However, the pigments found in these beverages can also stain your tooth enamel, so you may not be able to notice the stain on the restoration.
How strong is dental resin?
The strength of dental bonding Dental bonding is not as strong as tooth enamel. However, it is still strong enough to withstand daily pressure without breaking down. In fact, dental bonding can last for as many as 10 years with proper care. As mentioned, dental bonding is comprised of composite resin.
Polyester
Specific treatment of polyester varies depending on how the polyester is synthesized.
Resin Treated Polyester
While polyester dries quicker than many natural fabrics, applying a resin finish to polyester fabric makes the resin-treated areas water repellent. Resin also gives polyester a smooth, shiny appearance. Examples of polyester fabrics often treated with resin include swimwear, fiber batting, pillow cases and seat cushions.
Use of Resin for Water Treatment

Thermoplastic Resins
Thermoplastics account for a smaller part of the resins industry. They are sold as non-reactive solids, so no chemical reaction occurs during processing. Unlike thermosets, they require heat and pressure to create a finished material. Reheating and reforming is also possible.
Thermoset Resins
Thermosetting resins are designed to react chemically after deposition to form a three-dimensional network. Thermoset resins need a curing agent to be added prior to the impregnations onto a reinforcement. Curing of this material results in a solidified structure that cannot be remelted or reformed.
Polyesters
There are two classes of polyester resin: saturated and unsaturated polyester resin.
Epoxy
Epoxy resins contribute to the strength, durability and chemical resistance of a composite. They offer high performance at elevated temperatures, with hot/wet service temperatures up to 121°C.
Resin Curing
Resin curing is necessary to realise the benefits of its hardened state via the cross-linking of polymer chains. This process, in short, sees the transition of the resin from a liquid to a solid state. It is a primary feature of thermoset polymer production.

Not a chemical reactant in and of itself, IX resin is instead a physical medium that facilitates ion exchange reactions.
What happens to resin after it is exhausted?
Once the resin is exhausted, it must be restored for further use through what is known as a regeneration cycle. During a regeneration cycle, the IX reaction is essentially reversed through the application of a concentrated regenerant solution.
How does the IX resin work?
The IX resin functions this way because of its functional groups, which are essentially fixed ions that are permanently bound within the polymer matrix of the resin. These charged ions will readily bond with ions of an opposing charge, which are delivered through the application of a counterion solution.
What happens to the functional groups of the IX resin?
As the solution moves through the IX resin, the functional groups of the resin attract any counterions present in the solution.
What is a chelating resin?
Chelating resins are the most common type of specialty resin, and are used for selective removal of certain metals and other substances. In most cases the resin matrix is composed of polystyrene, though a variety of substances are used for functional groups, including thiol, triethylammonium, and aminophosphonic, among many others.
What is WAC resin?
WAC resins are composed of an acrylic polymer that has been hydrolyzed with either sulphuric acid or caustic soda to produce carboxylic acid functional groups.
