Radiation Resistant Coating
Definition - What does Radiation Resistant Coating mean?
Radiation resistant coatings are formulated materials that are cross-linked or cured using high-intensity radiation energy from electron beams or ultraviolet light radiation. The radiation resistant formulation contains a reactive liquid vehicle, pigments and conventional additives. These formulations are specifically designed for radiation curing.
Radiation resistant coatings have several advantages, including fast curing, low energy costs and improved surface properties that include improved corrosion protection for metals.
Radiation resistance coatings are also known as radiation cured coatings.
Corrosionpedia explains Radiation Resistant Coating
The radiation resistant coating process involves applying a low-viscosity mixture of reactive materials and additives onto a substrate. This is then exposed to an electron beam or ultraviolet radiation for a short period of time. Once exposed to the radiation, the mixture converts instantaneously into a cross-linked high-quality coating.
A typical mixture contains:
- Low-weight reactive materials such as oligomers and monomers
- A photoinitiator
- Surfactants, colorants, fillers, wetting agents, defoamers and other conventional paint coating additives
Advantages of radiation resistant coatings include:
- High production rate
- Low levels of volatile organic compounds (VOCs)
- Low energy consumption
- Durable, high-quality and consistent coating
- Enhanced scratch, impact, abrasion, chemical and mechanical resistance
- Expensive raw materials
- Adhesion problems caused by coating shrinkage
- Difficulty curing 3-D objects
Typical applications of these coatings include:
- Nuclear industry applications
- Automotive refinish applications
- Cold-rolled steel, aluminum, nickel, magnesium and brass
- Aerospace and defense
- Pipe and tubing steel pipes for oil drilling
