Epoxy phenolic coating is epoxy and phenolic resin as the main resin formulated by a certain percentage of the coating system, widely hand canned metal packaging sector, particularly in the beverage, food cans inside wall coatings based.
Epoxy refers generally refers to polymers containing two or more epoxy groups, an aliphatic, alicyclic or aromatic segment as a main chain. Therefore, paint and epoxy phenolic resin has two distinct advantages: with good adhesion to the metal substrate, excellent workability, excellent chemical resistance (resistance to sulfur in food packaging, acid resistance), good heat resistance and abrasion resistance, low shrinkage, low porosity.
Because epoxy phenolic coating has excellent corrosion resistance, and therefore, in the three-piece beverage, food cans and occupies a very important position in the two deep-drawing food cans, for example, in a variety of fruit juices, herbal teas and high acidity, high content sulfur coated food cans, etc. for use within. Typically, epoxy phenolic coatings show golden yellow, bright and full, but also has excellent physical properties (abrasion resistance and flexibility) and retort resistance, therefore, epoxy phenolic coatings are often used for miscellaneous tank coating and beverages, food cans top, bottom coated.
In the epoxy phenolic coatings often added aluminum paste or some zinc oxide used in the packaging of high sulfur-containing foods, such as meat, seafood, asparagus, mold release wax was added in the above system made of release coatings, can also be used canned luncheon meat packaging. The main role of aluminum paste is produced when hydrogen sulfide barrier coating and curing food sterilization through cover spots that may arise, the primary role of zinc oxide is produced when hydrogen sulfide absorption of food sterilization to prevent sulfide corrosion. But adding aluminum or zinc oxide paste epoxy phenolic coatings will result in a softer film, workability decreases.
