Abstract: A redox curable composition, methods for manufacturing same and uses thereof are disclosed. The redox curable composition is useful as a pre-applied adhesive. The redox curable composition is solid at room temperature, may be heated for application to a substrate, and cools to form a dry-to-touch adhesive layer on said substrate, which may be activated when required by mating with another substrate and exposure to an anaerobic environment. The composition is particularly suited to manufacturing complex products, such as mobile phones, computers and circuits.

Abstract: Methods and compositions for forming a coating layer on a substrate that include a) applying an aqueous coating composition to at least a portion of the substrate using a high transfer efficiency applicator that expels the coating composition; and b) curing the coating composition to form a cured coating layer. The aqueous coating composition includes an aqueous carrier, a film-forming resin having at least one crosslinking-functional group, and a co-reactive material having at least one functional group reactive with the crosslinking-functional group. The cured coating layer of the aqueous coating composition achieves 100 MEK double rubs as measured in accordance with ASTM D5402-19 (2019) after baking at 80°C for 30 minutes at coating thickness of 35 µm.

Abstract: Disclosed herein are methods for synthesizing oligomer mixtures with one or more moieties capable of forming a multi-hydrogen bonding dimer. The method comprises the steps of providing certain intermediate reaction products; adding a polyol component to the intermediate reaction product to yield an oligomer mixture comprising one or more multi-hydrogen bonding groups; and further reacting the mixture with certain isocyanate-reactive compounds to yield a multi-hydrogen bonding oligomer, wherein solvents comprise less than 50% of the total by weight of all reagents used in the synthesis of the multi-hydrogen bonding oligomer. Preferably, such methods involve no separation, distillation, or isolation of any intermediate product, and as such, they are particularly useful for a continuous or one-pot synthesis.
