Self-repairing car paint 'makes scrapes vanish'

Editors note: Most may know this, but we own Tamco Paint, an auto, OEM and coatings manufacturer located in Virginia that specializes in extra durable paints and coatings, as well as environmentally friendly ones. We have samples now of an additive that we can put into our clear coats that will self-repair scrapes made by BYK Inc. The additive can be added to most acrylic polyol resins and uses nano-technology that actually "heals" scratches that may occur in clear coats. We have them in the testing phase now. and will update this story as our evaluations are finalized. Tamco Paint is our family business that helps pay for The Plain Truth.

Scratches in car paintwork could become a thing of the past thanks to research that has made self-repairing paint a realistic possibility.

Scientists in the United States have developed a type of polyurethane coating that mends itself in less than an hour when exposed to sunlight. They plan to develop it as a paint for cars and other surfaces that are subjected to heavy wear and tear, as well as in new forms of packaging, clothing and biomedical products such as bandages.

Marek Urban and Biswajit Ghosh, of the University of Southern Mississippi in Hattiesburg, created the material using a natural substance found in the shells of crabs and shrimps.

Tamco.110 The coating consists of a network of ring-shaped molecules known as oxetanes, which split open when damaged, exposing two reactive ends. When this is exposed to ultraviolet light from the Sun, a chemical reaction allows a material called chitosan, which is found in crab shells, to repair the broken rings.
