An introduction to isocyanates in coatings, covering types, properties, reactivity and key formulation considerations for self-leveling urethane systems.
Polyols made with captured CO₂ offer coatings manufacturers a sustainable option that maintains durability and performance, supporting both quality and environmental goals.
The company received the certification at its PO/PG and polyols manufacturing site in Freeport, Texas, recognizing the implementation of decoupling fossil feedstocks by using waste-sourced feedstock.
Polycaprolactone (PCL) polyols can be used to enhance coatings that feature other polymer chemistries in both 1K and 2K coatings. This article explores the performance benefits achieved when low-molecular-weight PCL tri- and tetra-functional polyols are blended with other hydroxyl-functional polymers in 2K coatings.
Two of the more common 2K coatings systems are polyurethane and epoxy. This and next month’s Formulating with Mike column will concentrate on urethanes, with this issue focusing on polyurethane polymers.
Cast elastomers based on PDO-sebacate polyol exhibit an excellent combination of tensile properties, abrasion resistance, thermal, hydrolytic, and solvent resistance, as well as adhesion to metal substrates. These are desirable properties for cast elastomers intended for applications as protective coatings for pipes, and coatings for sieves typically used in drilling and mining applications.
A more sustainable industry requires the discovery and utilization of new raw materials and technologies, presenting an opportunity to develop products with unique properties not previously explored in the additives sector.
