Epoxy resins have been mainly used for interior coatings of food and beverage cans traditionally. Since this epoxy resin is composed by bisphenol A (BPA), a potentially endocrine disrupting substance, as a starting material, the coating contains a small amount of BPA. For this reason, TOYOCHEM, a subsidiary company of artience, has developed a new BPA-NI (Not Intent) coating that does not intentionally contain bisphenol A to alleviate people’s health and safety concerns, even at trace amounts. We named these specialized BPA-NI coating products as LIONOVA™ and are ready to provide them globally.

Acrylic emulsion type

Overview/Features

This acrylic emulsion is soap (emulsifier)-free. It is designed for hygiene and high temperature sterilization.
The core/shell structure is a key technology in this emulsion. Each core/shell has an important role to play in ensuring good quality.

Excellent feathering ability of LIONOVA™-500

Polyester type

Overview/Features

High performance polyester, which is the main resin, is composed by optimal functional groups in consideration of ideal cross-linking structure. We have achieved formability and barrier properties based on molecular weight and glass transition point (Tg).
