Foconsci’s 2-Octyl-2H-Isothiazol-3-One (OIT) is an isothiazolinone fungicide mainly used to protect dried coatings and other finished materials from mold and fungal growth.

Compared with preservatives mainly used to protect the product inside the container, OIT is especially suited to dry-film protection. It stays in the finished coating, sealant, plastic, leather or wood treatment and helps prevent mold growth during use.

Plastics and Building Materials: OIT can be added to polymer and construction-material systems that need long-term surface protection against fungal growth.

Leather and Textiles: OIT helps protect leather, coated fabrics and textile materials from mildew during storage and use.

Wood Protection: OIT is used in wood-preservative systems to control fungi and mold on treated wood and wood products.
