Perfectly safe and produced from an annually renewable feedstock, isosorbide has a unique combination of properties that offers excellent potential for a range of CASE applications.
A multi-step continuous process has been developed to convert renewably sourced furfural to 1,5-Pentanediol (1,5-PDO), which is a low-cost renewable replacement for 1,6-HDO, a diol intermediate currently used to produce coatings, adhesives and plastics.
Development of eco-friendly, sustainable and high-solid (low-VOC) coatings have received a lot of attention due to environmental concerns and legislative issues.
Although often not appreciated, it is important to recognize is that how you conduct your process has a profound impact on where the acid groups reside and therefore on your final product properties.
Whatever your reasons for varying the monomer feed rates, be aware that there may be unintended effects; in addition to the desired outcome, some product properties may also change.
Ymer N90, with a longer EO chain, and N180, with a shorter EO chain, allow customers to formulate solvent-free PUDs and minimize the level of harmful amines in production and during application.
This article presents a new family of polymers, which combine vinyl (neo)ester and vinyl alkoxysilane monomers. Variation of process parameters, monomer composition and alkoxysilane levels yielded a series of polymers with solids content between 70 and 100%, and exhibiting a wide range of attractive properties.
Despite the challenges of reformulating a coating from solvent‐based to waterborne and curing a low-molecularweight EPDM at ambient temperature, formulations have been successfully developed utilizing peroxide, oxidative and UV-curing systems.
