SILYLAMINE COMPOUND AND LATENT CURING AGENT COMPRISING SAID SILYLAMINE COMPOUND
An object of the present invention is to provide a compound suitable for use as a latent curing agent, which does not produce an aldehyde compound when caused to react with an isocyanate compound. The present invention provides, as the compound, a silylamine compound represented by the following formula (1):
##STR00001##
in the formula (1), R.sup.1 to R.sup.12 each independently represent an alkyl group having 1 to 6 carbon atoms, R.sup.13 represents an alkylene group having 2 to 12 carbon atoms or an arylene group having 6 to 12 carbon atoms, R.sup.14 to R.sup.21 each independently represent a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, “y” and “z” each independently represent an integer of from 1 to 11, and “n” represents an integer of from 1 to 43.
TIRE WITH REDUCED CAVITY NOISE
Disclosed is a tire with reduced cavity noise including an adhesive agent layer applied to an inside an inner liner, and a sound absorber layer attached to the adhesive agent layer, wherein the adhesive agent layer includes polyether containing an alkoxysilane substituent group in a main chain, rather than, at an end. The tire with reduced cavity noise is stable without causing separation of a sound absorber even heating and deformation during driving.
High-durability antifogging coating film and coating composition
The problem addressed by the present invention is to provide an antifogging coating film having excellent antifogging property, antifogging persistence, persistence of appearance, and elution resistance. The coating film according to the present invention contains a metal oxide (A) and a hydrophilic compound (B); the height of the eluate by a coating film surface elution test is 1.0 μm or less; this test is carried out by placing 10 μL of deionized water on the coating film, allowing the film to stand for 24 hours in a 23° C., 50% RH environment, measuring the eluate height of 20 locations selected randomly within a 10 cm.sup.2 range on the coating film surface, and determining the maximum height; and the water contact angle measured after subjecting the coating film to a moisture resistance test by exposure for 24 hours in an 85° C., 85% RH environment followed by standing for one hour in a 23° C., 50% RH environment, is less than 40°. Preferably, the elution level per coating film unit volume by a coating film total elution test is 40 mg/cm.sup.3 or less, and this test is carried out by immersing the coating film in 23° C. deionized water for 24 hours, then measuring the weight of the coating film eluate recovered from the deionized water.
