Abstract: The present invention provides a UV curable adhesive, wherein based on a total weight of the UV curable adhesive, the UV curable adhesive comprises: from 30 to 70 wt % of an acrylate oligomer; from 20 to 65 wt % of an acrylate monomer; from 1 to 10 wt % of acryloyl morpholine; from 1 to 15 wt % of a photo initiator; and from 0 to 10 wt % of a thickening agent, wherein the acrylate oligomer has a weight average molecular weight in a range of from 10,000 to 100,000 grams/mole and a glass transition temperature in a range of from −50 to 0° C. According to the technical solution of the present invention, the adhesive layer obtained from curing the UV curable adhesive is relatively thick (for example, 0.8 mm), and the adhesive layer has good adhesion property, cohesive force, and tackiness.

Abstract: Disclosed is a curable composition and cured products thereof. The curable composition includes a vinyl polysiloxane component, a hydrogen polysiloxane component, a polymerization catalyst, and an expandable graphite component comprising moisture. Cured products of the curable composition include foamed cells having a uniform size and distribution in the cured product. This can help to increase the water proofing and flame retardant properties of the cured product.

Abstract: The two-part composition includes a first part and a second part. The first part includes a vinyl-substituted polysiloxane, a hydrosilylation catalyst, expandable graphite comprising moisture, and first polymeric microspheres having been at least partially coated with inorganic filler. The second part includes a second vinyl-substituted polysiloxane, a hydrosilyl-substituted polysiloxane, and second polymeric microspheres having been at least partially coated with flame-retardant inorganic filler. The two-part composition is useful, for example, for curing into a sealant and making an assembly. The assembly has a first substrate and a second substrate with a cured product of the two-part composition in contact with the first substrate and the second substrate. Methods of making a sealant and an assembly are also described.

Abstract: 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.
