Applications

1. Printing Inks & Coatings A fast-drying film-forming resin for gravure and flexographic inks, varnishes and coatings. Excellent adhesion, gloss and abrasion resistance deliver high-quality printing on metal, plastic and paper substrates.

2. Microencapsulation & Taste Masking An ideal wall material for microencapsulation of flavors and active ingredients. Provides moisture protection and controlled release while masking unpleasant tastes in oral formulations.

3. Adhesives & Specialty Applications A thermoplastic binder for hot melt adhesives and specialty formulations. Improves cohesion, flexibility and processing stability in demanding applications.

4. Food & Nutraceutical Applications A food-grade stabilizer and film-forming agent for food and nutraceutical products. Low use levels deliver effective performance with safe, compliant quality.

5. Ceramic & Electronic Applications Used as a binder in ceramic and electronic pastes and specialty coatings. Consistent viscosity and thermal behavior support reliable processing performance.
