Abstract: Applying heat activatable adhesive to a substrate, the adhesive is solid at ambient temperature and can be melted at a temperature below its heat activation temperature wherein the adhesive formulation is supplied to a hot melt applicator where it is heated to above its melting point and below its activation temperature and the melt viscosity of the molten adhesive is controlled so that it can be ejected from the hot melt applicator onto a substrate to provide a coherent bead that adheres to the substrate and is dry to the touch on cooling and upon activation the adhesive is capable of expanding with a volume expansion greater than about 250%.

Abstract: The invention relates to a potting paste composition for honeycomb reinforcement having improved fire retardancy characteristics. The potting paste composition comprises (a) a curable polymer; (b) a curing agent for the curable polymer; (c) a fire retardant comprising an ammonium polyphosphate in combination with an ingredient selected from the group consisting of metal hydroxides, expandable graphites, liquid phosphate esters, phosphorous organic compounds or salts thereof, and zeolites; and(d) a filler selected from the group consisting of polymeric microspheres, hollow glass microspheres, and thixotropic fillers; wherein the potting paste has an uncured density determined by the method according to EN ISO 1183 of not more than 0.7100 g/cm3, preferably of at most 0.680 g/cm3, more preferably of at most 0.673 g/cm3, still more preferably of at most 0.660 g/cm3, even more preferably of at most 0.658 g/cm3, yet more preferably of at most 0.653 g/cm3 and in particular of at most 0.

Abstract: The invention relates to a two-component structural adhesive, i.e. to a two-component system of a first component and a second component spatially separated from one another, wherein the reaction of the first component and the second component after mixing results in a structural adhesive. The first component comprises at least four of a (meth)acrylic acid, a C1-6-alkyl (meth)acrylate, a cycloalkyl (meth)acrylate, a hydroxy-C1-6-alkyl (meth)acrylate, and/or a glycolether (meth)acrylate. The second component comprises a peroxide polymerization initiator. Additionally, the first component and/or the second component comprises at least two toughening agents (a first toughening agent and a second toughening agent); the second toughening agent differing from the first toughening agent; a first impact modifier; and optionally a second impact modifier differing from the first impact modifier.

Abstract: The invention relates to a structural adhesive formulation, which is heat activatable at a heat activation temperature; meltable without heat activation at an application temperature above its melting point and below the heat activation temperature; and solid at ambient temperature; wherein upon heat activation the structural adhesive formulation is capable of expansion with a volumetric expansion of up to about 250 vol.-%; wherein the heat activatable structural adhesive formulation comprises (a) an epoxy resin component; (b) an adhesion promoter component; (c) a cross-linking component; (d) a blowing component; (e) optionally, an impact modifier component; (f) optionally, a thixotropic filler component; and (g) optionally, a non-thixotropic filler component. The structural adhesive formulation is particularly useful for application by means of a hot melt applicator, preferably a hand held hot melt gun.
