The present invention relates to a thermally expandable composition comprising at least one peroxidically crosslinking polymer which does not contain glycidyl (meth) acrylate as a monomer in copolymerized form; at least one polymer, which is polymerized with glycidyl (meth) acrylate as a monomer present in a proportion of from 2 to 20% by weight, based on the respective polymer; at least one peroxide; and at least one endothermic chemical propellant, moldings containing this composition, and a method for sealing and filling cavities in components, for reinforcing or stiffening components, in particular hollow components, and for bonding movable components using such molded bodies.

The present disclosure relates to adhesives useful in preventing drifting during lamination of light redirecting films applied to photovoltaic cells. The adhesives of the present disclosure have other useful applications in bonding and/or affixing other solar energy components.

A method of making an adhesive for an ice protection assembly includes mixing ferrous nanoparticles into the adhesive. Removal of the adhesive for ice protection assembly inspection or repair includes heating the ferrous nanoparticles in the adhesive to soften the adhesive and allow for easy removal or repositioning of the ice protection assembly.

The present disclosure provides an article. The article includes a crosslinked foam composition, an adhesive layer, and a substrate composed of an olefin-based polymer. The crosslinked foam composition includes an ethylene/a-olefin multi-block copolymer, an ethylene/propylene/diene terpolymer (EPDM), optional silicone rubber, optional blend component selected from ethylene/aolefin random copolymer, ethylene-vinyl acetate copolymer (EVA), styrene-butadiene block copolymer, hydrogenated styrene-butadiene block copolymer, and combinations thereof, optional plasticizer, optional filler, and optional additive.

The present invention provides a UV curable composition, a UV curable adhesive film and a UV curable adhesive tape. The UV curable composition comprises, based on the total weight thereof as 100 wt %: 25 to 60 wt % of an ethylene-vinyl acetate copolymer; 20 to 60 wt % of an epoxy resin; 5 to 20 wt % of glass bubbles; 0.3 to 8 wt % of a hydroxy-containing compound; and 0.5 to 5 wt % of a photoinitiator. According to the technical solution of the present invention, cohesive failure can be achieved in the cured adhesive film by the addition of glass bubbles into the UV curable system. The UV curable product provided in the present invention can achieve a good balance among the initial adhesivity, structural strength after curing, odorlessness or low odor, and other performance.
