Coatings & gel coats
In a variety of applications, such as yachts, pipes, or rotor blades for wind turbines, the composite has to be protected against, for example, sunlight, humidity, and abrasion. In such cases, or for surface refinement, coatings or gel coats are used.
Composite materials exhibit a limited weathering durability, which is attributable to the inherent properties of matrix
systems used nowadays, such as epoxy or unsaturated polyesters.
For applications where light stability is not required, epoxy resin systems are often used as gel coats.more
