Industrial Applications

Coatings & Paints

Slow-evaporating diluent for alkyd, epoxy, and polyurethane coatings. Low aromatic content meets VOC and odor requirements for interior applications.

Adhesives & Sealants

Carrier solvent in contact adhesives and construction sealants where low odor and controlled evaporation are required.

Cleaning & Degreasing

Effective degreaser for metal parts, molds, and industrial equipment. Low toxicity profile versus aromatic alternatives.

Printing Inks

Diluent in gravure and flexographic inks. Slow evaporation supports open time and print quality.

Aerosol Formulations

Carrier in aerosol lubricants, mold releases, and maintenance sprays where low odor is critical.

Textile & Leather

Solvent in leather finishing and textile processing where dearomatized solvents are specified.
