Odor defines the first impression of coatings. For interior walls, low-odor formulations are essential. Achieving this requires raw materials with minimal odor and stable hydrolysis properties.
The LOCA® series offers odorless, non-VOC film-forming additives that reduce odor and ensure excellent stability, all while saving 20–30% in dosage.
For low-emission coatings, LOCA® A+ is the perfect choice. With a boiling point of 299°C and no TVOC contribution, it ensures superior film formation and reduces additive use by 30%, offering an efficient, eco-friendly solution.
Art coating brings beauty and versatility to interior walls—but their unique application demands ultra-low odor and emissions.LOCA® and LOCA® A+ low-odor film-forming additives meet these needs, ensuring clean, high-performance formulations.
For thick, textured coatings, LOCA® offers a three-component blend with gradient volatilization for superior film formation. For emission-certified coatings like France A+, LOCA A+ is the ideal choice—reducing additive usage by 30% while delivering a cost-effective, eco-friendly solution.



Acrylic paint for children demand more than low odor—they require safer, healthier raw materials. Traditional dodecyl additives have strong odors, while hexadecyl options carry reproductive toxicity risks.
LOCA® odorless film-forming additives are the safer choice. With ultra-low odor, fast evaporation, and high efficiency, they reduce additive usage by 30%—delivering a healthier, environmentally friendly solution for acrylic paints.


High-performance exterior coatings demand more from film-forming additives. LOCA® outperforms traditional dodecyl additives with superior emulsion compatibility, tighter film formation, and enhanced weather, water, and low-temperature resistance—all while reducing dosage by 20–30%.
Field tests confirm: LOCA® cuts additive use by 20% and delivers outstanding early water-whitening resistance, even at 5°C in high humidity.
