Polyalcohols

Polyalcohols are the cornerstone of many resin systems, from durable polyesters to high-solids alkyds. Perstorp’s key polyalcohols, Trimethylolpropane (TMP) , Pentaerythritol (Penta), and Neopentyl Glycol (Neo), provide structure, hardness, and long-term stability in coatings that need to perform under tough conditions. Each of these products is also available as a Pro-Environment version, produced from renewable raw materials with identical quality and performance.

Our broader portfolio also includes products such as Di-Penta, Di-TMP, and CTF, giving formulators additional tools to fine-tune performance in demanding resin and coating systems.

Alkoxylated Polyalcohols

Alkoxylated polyalcohols are tailored solutions that give formulators extra control over reactivity, solubility, and processing. Alkoxylates are fine-tuned to the specific needs of resin systems.

These versatile products are used across polyurethane, polyester, and radiation-curable, coatings where balanced flow, flexibility, and consistency matter. They help achieve the right balance between formulation freedom and dependable results, even in demanding or moisture-sensitive applications.
