Title:
RELEASE AGENT FOR REACTIVE HOT MELT RESIN
Document Type and Number:
WIPO Patent Application WO/2019/017133
Kind Code:
A1
Abstract:
The present invention provides a release agent for a reactive hot melt resin, the release agent being characterized in that in the Hansen solubility parameter, the dispersion component (δD) falls within the range 14.0-21.0 MPa0.5, the dipole-dipole force component (δP) falls within the range 0-10.5 MPa0.5, and the hydrogen bonding component (δH) falls within the range 0-13.5 MPa0.5. This adhesive for a reactive hot melt resin is preferably one or more solvents selected from the group consisting of benzoic acid esters, tetrahydrofurfuryl alcohol and tetrahydrofurfuryl (meth)acrylate. This reactive hot melt resin preferably contains an isocyanate group-containing urethane prepolymer, and the content of urethane bonds in the urethane prepolymer preferably falls within the range 0.1-3 mol/kg.
