Resin is a plant secretion or synthetic material used in everyday objects such as paints, varnishes, plastics, furniture, and medicines. Resin products offer longer life, better adhesion, and greater chemical and corrosion resistance. They are also used in DIY projects, furniture, and medical fields. Resin can be recycled and is used in cholesterol-lowering drugs and art/crafts.
Natural resin is a solid or semi-solid material that occurs as a plant secretion, such as pine sap. Synthetic resins, which can be produced chemically, are generally more stable than natural sources. Resin products are used in a multitude of everyday objects ranging from paints, varnishes and building materials to plastics, jewellery, art, furniture and medicines.
Synthetic liquid resin is found in specialty coatings, inks, varnishes, and sealants. Coating products containing resin offer longer life, better adhesion, and greater chemical and corrosion resistance than non-resin products. Most paints adhere to wood, but resin-based paints also adhere well to more difficult surfaces such as metal, plastic film, and glass. Liquid resin products are also used for windshield repairs.
Homeowners who are into DIY projects invariably use resin products. It can be found in the paint they choose for their exterior, the finish for their new hardwood floor, or the building materials for a new fence or deck. Resin decks and fences are more expensive than wood, but require virtually no maintenance. Unlike wood, the color baked into resin will not fade, chip or chip when exposed to sun, rain and snow.
Once home improvement projects are completed, a person can relax on a variety of resin products, such as chairs, picnic tables, and playground equipment. Bar stools, benches, wicker rockers, coffee tables, and storage units are other examples of the furniture made from this versatile substance. Another benefit of plastic resin products is that they can be recycled, reducing the amount of waste going to landfills.
The resin has even entered the medical field. In the past, most dental fillings and crowns were made from silver or gold. Composite resin fillings that are colored to match surrounding teeth have been created as an attractive alternative to metal. They are strong and durable, and some insurance companies will pay the extra cost if the tooth being treated is near the front of the mouth where the filling or crown will be visible. The resin is also used in dental cement and bridges.
Some cholesterol-lowering drugs contain bile-binding resins. These drugs bind to the bile released by the liver, preventing it from being absorbed through the intestines and into the body. Since bile is mainly composed of cholesterol, resin products essentially reduce the supply of cholesterol to the body. Other resin-containing medications help relieve symptoms of irritable bowel syndrome or provide topical treatment for genital warts.
Artists and craftsmen also use a variety of resin products. Acrylic resins can be mixed with water and poured into silicone rubber molds to make models, statues, vases and other items. When dry, they have a ceramic-like sound, but do not require the firing and curing time of ceramics. Casting resins are available in both urethane and polyurethane.
