A composition capable of radiation activated catalysis is provided. The composition comprises a metal compound, a mercapto compound and an olefinic compound. Radiation curable urethane compositions comprising the disclosed composition are also provided. The radiation curable urethane compositions comprise the disclosed composition, a hydroxyl compound and an isocyanate compound. Activation of the composition by radiation in a urethane formulation provides for an efficient method of curing the urethane composition. Coating and adhesive compositions comprising the radiation curable urethane compositions are also provided. In addition, methods for coating and bonding substrates are disclosed.
A method of coating an article comprising applying a coating composition to the surface of the article then irradiating the coated article with radiation to cure the coating composition wherein the coating composition comprises a radiation curable urethane composition comprising a) a composition capable of radiation activated catalysis comprising a metal compound having catalytic activity, a mercapto compound which passivates the metal compound by inhibiting the catalytic activity of the metal compound, and an olefinic compound which reacts with the mercapto compound wherein the reaction between the mercapto compound and the olefinic compound is caused by the radiation;
An adhesive composition comprising a radiation curable urethane composition which comprises a) a composition capable of radiation activated catalysis comprising a metal compound having catalytic activity, a mercapto compound which passivates the metal compound by inhibiting the catalytic activity of the metal compound, and an olefinic compound which reacts with the mercapto compound wherein the reaction between the mercapto compound and the olefinic compound is caused by the radiation;
