KETJENFLEX® 8

KETJENFLEX 8 is a highly polar sulfonamide-based plasticizer designed to improve performance in packaging inks. It provides exceptional adhesion to challenging substrates like PET, BOPP, and foil, ensuring strong lamination bonds in multiwall systems. The additive enhances flexibility and film integrity while delivering high gloss and aesthetic appeal in nitrocellulose and polyurethane ink systems. Its thermal and chemical stability supports demanding processes such as high-speed lamination without risk of delamination. These properties make KETJENFLEX 8 a trusted solution for durable, high-quality packaging inks in food and consumer applications.

KETJENFLEX 8 acts as a high-performance plasticizer and flexibilizer across soluble matrix, insoluble matrix, and self-polishing antifouling systems. It promotes smooth film formation and strong adhesion to primer layers, ensuring uniform ablation without cracking or delamination. The additive enhances resistance to oil, solvents, and water while providing UV and thermal stability for long-term durability. Its lubricating effect supports controlled erosion in ablative coatings, improving foul-release efficiency and maintaining hull smoothness. These combined properties make KETJENFLEX 8 essential for marine coatings that demand flexibility, stability, and reliable antifouling performance.

KETJENFLEX 8 acts as a premium plasticizer for nitrocellulose wood coatings, delivering excellent compatibility with NC resins and ensuring smooth film formation. It enhances gloss and aesthetic appeal while improving flexibility and adhesion, reducing brittleness in one-component lacquer systems. The product also provides resistance to solvents and moisture, contributing to better durability and reduced bleeding. Its performance surpasses conventional phthalates, offering superior stain resistance and mechanical properties such as scratch resistance and elasticity. These attributes make KETJENFLEX 8 ideal for high-quality wood sealers and topcoats where clarity, quick drying, and easy repair are essential.

KETJENFLEX 8 serves as an adhesion promoter and plasticizer in vinyl resin-based heatseal lacquers, ensuring strong and reliable sealing performance for packaging applications. Its high polarity improves bonding to challenging substrates like aluminum foil and PET, critical for yogurt cups, cheese wraps, and pharmaceutical blister packs. The additive enhances flexibility and film integrity while maintaining clarity and gloss under demanding lamination conditions. It provides excellent resistance to oils, solvents, and moisture, supporting durability and compliance with food-contact regulations. These properties make KETJENFLEX 8 a trusted solution for high-performance heatseal adhesives in the packaging industry.
