Abstract: A two component polyurethane adhesive composition having one or more polyols as a first component and one or more isocyanates as a second component. The composition also comprises one or more catalysts and one or more blocking agents to delay the curing reaction. The composition provides long open time, improved wet out of the substrates to be bonded, a rapid cure rate and excellent final bond performance at room and elevated temperatures. Optional ingredients, such as fillers, chain extenders and plasticizers may be added as desired. In one embodiment, the catalyst is a tin catalyst such as dibutyl tin dilaurate which may optionally be combined with other catalysts such as tertiary amines. The blocking agent in one embodiment is 8-hydroxyquinoline.
Abstract: A filler-containing an organic polymer dispersion is provided. The organic polymer of the dispersion is polymerized in the presence of particles of at least one filler. The ratio of the particle size of the filler particles to the particle size of the polymer particles is in the range of from 1.1:1 to 20:1.
Abstract: A curable composition for forming anisotropically conductive bonds comprising: (i) an amount of first substantially uncured curable component; (ii) conductive particles coated with a substantially uniformly thick coating of the cure product of a second curable component dispersed within the first curable cyanoacrylate component. The composition is suitable for use as an adhesive composition for bonding chips to electronic circuits. Desirably the first component and the second component are both cyanoacrylates.
Abstract: The objective of the present invention is to provides a cationically curable epoxy resin composition excellent in sealing and adhesive property specifically to glass, excellent reflow resistance property, moisture resistance and water resistance while keeping a good workability intrinsic to a light curable resins.
