Nychem® 552

Nychem® 552 is one of our Specialty Emulsion offerings. It is a high solids blend of a noncarboxylated acrylonitrile butadiene copolymer latex with a polyvinyl chloride dispersion. It contains no plasticizer. It features a combination of good oil, grease and hydrocarbon resistance, toughness/resilience, and tear and abrasion resistance. Nychem® 552  also possesses good toughness/resilience, and tear and abrasion resistance. It is also nonblocking. Toughness, abrasion resistance and chemical resistance can be further enhanced though either vulcanization or by adding external crosslinking agents such as melamines, epoxies, phenolics or metal complexes. Nychem™ 552 is stabilized with natural surfactants so it exhibits excellent water and alkali resistance. Common applications include release coatings and textile coatings.
