PALS free volume study of dry and water saturated epoxies. (positron annihilation lifetime spectroscopy)
September 1, 1997... INTRODUCTION Crosslinked epoxy resins are used as protective coatings. A protective coating forms a barrier to prevent corrosion due to transport of the reactants or corrosives (such as water, oxygen, and ions) through the coating to the...

Quantitative and structural aspects of crosslinking near film-air and film-substrate interfaces in solvent-borne polyurethanes.(Interfacial Studies of Crosslinked Polyurethanes, part 1)
September 1, 1997... INTRODUCTION Although urethane-based polymers have been extensively studied,[1,4] there are various aspects of the urethane chemistry that are not fully understood. For example, kinetics and thermodynamics of the crosslinking reactions near...

Study of anionic polyurethane ionomer dispersant.
September 1, 1997... INTRODUCTION The compatibility of powders[1,2] dispersed in water is highly dependent on how close they are in polarity. Addition of a surfactant may enable the powder to be successfully dispersed as a result of changing the powder's polarity....

Influence of crosslink density, glass transition temperature and addition of pigment and wax on the scratch resistance of an epoxy coating.
September 1, 1997... INTRODUCTION Scratch resistance is a highly desired but little understood property of coatings. It depends on the intrinsic properties of the coating material in a way that still is largely unknown. Many workers have tried to relate mechanical...
