ABSTRACT:
Disclosed is a composition containing a novel ungelled resin in combination with an effective amount of a cure-promoting catalyst selected from the group consisting of triflic acid (i.e., trifluoromethane sulfonic acid), a neutralization product of triflic acid with ammonia, a neutralization product of triflic acid with an amine, a tetraalkyl ammonium salt of triflic acid, and mixtures of one or more of the aforesaid catalysts. The composition can be cured with moisture and/or with polyols and can be used to provide protective and/or decorative films on a variety of substrates.
The novel ungelled resin comprises a compound corresponding to a specified formula (I) which compound typically is prepared by reaction of an aminoalkyloxy silane with an organic isocyanate. The ungelled resin contains a hydrolyzable group that is attached directly to silicon.
