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.
In this experiment, NaSS showed the best performance in terms of mechanical stability, foaming and water absorption. This was attributed to the good polymerizability and surface activity of NaSS. But there is still room for improvement, especially water resistance.
Because of their versatility, methylene malonate monomers have shown potential in a wide variety of applications, such as one- and two-component clear coatings for automotive and industrial use, adhesives for packaging and industrial use, waterborne coatings and adhesives, pressure-sensitive adhesives, encapsulated pigments, and composite binders.
Gelest Inc., a materials science innovator and New Mountain Capital portfolio company, announced the acquisition of Bimax, a manufacturer and marketer of specialty monomers and polymers.
Suitable as a reactive diluent in UV-curing inks and coatings, vinyl methyl oxazolidinone (VMOX) is liquid at room temperature and has a very low viscosity of ca. 4 mPa.s.
Sirrus Inc., a developer of electron-deficient monomers and oligomers, has completed construction of a $2 million bench plant expansion to increase production of methylene malonate monomers and oligomers.
LM (low-migration) acrylate monomers and oligomers are designed for the formulation of UV-curable inks and coatings dedicated to indirect food contact applications.
