What Does
Oleoresinous Phenolic Coating Mean?
Oleoresinous phenolic coating is a type of coating that contains a resin known as oleoresin. This resin is a naturally occurring resin and oil mixture obtained from a variety of plants, such as balsam fir and pine. This type of resin is referred to as balsams and is considered to be a soft variety that may contain cinnamic acid and benzoic acid.
Corrosionpedia Explains Oleoresinous Phenolic Coating
This phenolic coating contains the resin oleoresin, which is prepared by cooking phenolic resin with drying oil. They are similar to epoxy-based phenolic coatings, however, they are a cost effective substitute for epoxy phenolic coatings.
Oleoresinous phenolic coatings are primarily used to manufacture food containers because these ploymers have proven corrosion and chemical resistant properties when used at higher temperatures. Unfortunately, phenolic coatings sometimes alter the food's flavor.
