Acrylic resins are synthetic resins and are considered particularly durable. Acrylic resins are based on Polimerisaten or copolymers of acrylic acid, methacrylic acid and their esters. They will often copolymerized with other unsaturated monomers, such as styrene or acrylonitrile. The resins may be thermally self-curing, if functional groups such as Wear hydroxymethyl groups or they are crosslinked to cure with other resins such as epoxy resins or amino resins.
Acrylic resins are used in many adhesives and coatings. A purpose is the building waterproofing. Generally, acrylic resins possess a very wide range of applications in the coatings industry. Acrylic resins, once cured, permanently durable and resistant, they have a good appearance, good gloss and high resistance to weathering. Acrylic resin sealants is also paintable, which is why preferred for sealing cracks in the wall acrylic to silicone - like substances. The exclusive use of pure acrylic resins on metal offers only moderate protection against corrosion. A satisfactory result is achieved by an appropriate primer. Also for acrylic resins are used, but they are with appropriate additives ( coupling agents ) and pigments provided. Then is covered with acrylic resin, here again the use of appropriate fillers, is necessary. This system is widely used, for example in steel bridges. When processing the safety precautions are observed. Escaping monomers can cause headaches.
Photo-initiated curing acrylates
Photoinitiated curing acrylates were made one-component, room temperature curing reactive resins, the free-radical polymerization by UV or visible light. Photo-curing acrylates is used for the bonding in which at least a joining portion of a light transparent material. These adhesives are used in communication electronics, consumer electronics, glass and plastics industry and in medical technology. The product properties range from an ultra-fast curing for short cycle times in production, have high ionic purity and wide range of elasticity to the ability to combine different materials such as glass, ceramics, metal, plastic or wood together.
