Acrylic resin (AR) conformal coatings are one of the most common conformal coatings used today. The coatings are single-component materials; more specifically, they are pre-formed acrylic polymers that are dissolved in a solvent to be applied to surfaces.
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. The IUPAC name for an epoxide group is an oxirane.
