What caused the hexagonal pattern to form on the surface of a modified formulation with more solvent? Read Moody’s Coatings Conundrums to learn more about this formulating challenge.
Easy to process, highly transparent and extremely color pure, SynAdd serves to improve technical properties such as weather and moisture resistance as well as scratch resistance.
To obtain continual improvements in scratch- and abrasion-resistant coatings, a variety of additive technologies have been developed to address this issue. In this study, the article examines additive technologies ranging from surface-active siloxanes and nanocomposite technology to synthetic amorphous silica and co-binders.
Easily dispersible in water, the polycarbonate diol Duranol W8011 improves the chemical and scratch resistance, adhesion, softness and self healing of coatings.
Aliphatic urethanes with high acrylate functionality result in cured films having excellent abrasion resistant properties. The family of UV-PUD materials examined offers a higher reactive solid content at a lower viscosity when compared to typical UV-PUDs on the market.
This paper will review the current use of silica nanoparticles in UV-curable coatings and introduce effective approaches for delivering silica nanoparticles to UV-curable resin formulations without the drawbacks of current solvent- or monomer-based silica nanoparticle dispersions.
