Key advantages
Alcosperse® OTA‑100 is designed for broad use in water‑based paints and fits easily into existing manufacturing processes. Key advantages include:
- Longer open time, which helps paint stay workable and improves ease of application
- Low odor, which supports growing consumer expectations for more pleasant indoor painting experiences
- Ability to reduce or replace glycol, an ingredient many producers want to minimize because it contributes to odor and higher levels of VOC
- Compatibility across a wide range of formulations
"Alcosperse® OTA‑100 helps formulators meet the demand for easier to use architectural paints while reducing reliance on glycol. It is a practical way for producers to advance their low- and zero-VOC product lines without sacrificing quality," said Joe Ferrara, vice president of Paints & Coatings at Nouryon.
