Global specialty chemicals company Nouryon has introduced Alcosperse OTA‑100, a new polymer additive that helps paint manufacturers create water‑based architectural paints that are easier to apply and aligned with growing demand for low‑odor products with reduced levels of volatile organic compounds (VOC). The technology supports producers seeking paint options that deliver a smooth, consistent finish.

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.

In customer trials, Alcosperse OTA‑100 has been shown to work across a wide range of water‑based paints and has minimal impact on durability, and scrub, stain and water resistance. It is available in the Americas and Europe and can be incorporated into many current formulations with minimal changes. Technical support is available through Nouryon’s global Paints & Coatings application centers.

Within Nouryon’s Performance Materials segment, this new product is part of the company’s Paints & Coatings portfolio, which offers a range of solutions that deliver tailored performance benefits. For more information about Nouryon’s additives, visit or contact your local sales representative.
