Title:
RUBBER-TYPE CURABLE HOTMELT ADHESIVE
Document Type and Number:
WIPO Patent Application WO/2008/004376
Kind Code:
A1
Abstract:
The object is to provide an one-part curable hotmelt adhesive which is free from a concern about ecological problems which are inevitable to a solvent-type curable adhesive, inconvenience in handling which is inevitable to a moisture-curable polyurethane-type hotmelt adhesion or a conventional two-part curable hotmelt adhesive, and such an economical absurdity that an adhesive agent should be discarded before and after the processing. Disclosed is a rubber-type curable hotmelt adhesive. In the adhesive, a reactive composition composed mainly of (A) an acid anhydride-modified copolymer, (B) an epoxy resin, (C) a non-reactive block copolymer, (D) an adhesiveness-imparting agent and (E) a plasticizer is reacted with (F) a cure-promoting agent on the surface of the composition, thereby creating a curing reaction gradient from the surface of the composition toward its inside.
