Productivity is an important factor in production, and fast-curing sealants, adhesives, and coatings are cost savers. Typically, reactivity comes at the cost of flexibility in cured epoxy products, as high flexibility can generally only be obtained by using high-molecular-weight amine-based polymers. The new polythioether … See more Epoxy systems are well-known for their high tensile strength. However, when conventional curatives are involved, this comes at a lack of flexibility and impact strength. Used as the … See more Most polymeric materials suffer from insufficient stability against UV exposure and will undergo photo-initiated degradation. One example is epoxy-based systems. UV light can … See more In many cases, epoxy resins are the first choice whenever an adhesive or coating must withstand harsh chemical conditions. One reason that epoxy resins resist chemical … See more Used in its pure form or as an additive with other curatives, the polythioether cures epoxies, isocyanates, or unsaturated systems such as … See more WebA series of cobaltocenium-containing polythioether type metallo-polyelectrolytes with different linkages and substituents were synthesized by photo-induced thiol–ene …
