Disclosed are polyurea compositions and methods for using such composition as sealants, such as construction sealants.

Disclosed are polyurea compositions and methods for using such composition as sealants, such as construction sealants.

The present disclosure provides compositions, films and articles containing a random propylene/ethylene copolymer and a substituted phenylene aromatic diester. Polymerization with an improved catalyst system increases the amount of ethylene incorporated into the random propylene/ethylene copolymer backbone which results in improved thermal properties, improved optical properties, and improved heat seal properties.

The invention relates to a two-component composition, including a component A, which includes at least one silane-functional polymer and at least one hardener or accelerator for epoxy resins, and a component B, which includes at least one aqueous emulsion of at least one epoxy resin. Two-component compositions according to the invention are suitable as adhesives, sealants or coatings.

A curing agent mixture is for coatings that cure at room temperature. The curing agent mixture can include (A) 10-60% by weight, preferably 20-60% by weight, more preferably 30-50% by weight, of a polysiloxane, (B) 40-90% by weight, preferably 40-80% by weight, more preferably 40-70% by weight, of an amino-functional alkoxysilane and (C) 1-10% by weight, preferably 2-7% by weight, more preferably 3-5% by weight, of a guanidine compound. The stated amounts of components (A), (B), and (C) add up to 100% by weight and are based on the curing agent mixture.

A sealing body for dynamic applications has a Shore A hardness of between 60-100, comprising an elastomer material and carbon nanotubes distributed in the elastomer material in an amount of between 0.1-20 phr, with respect to the total amount of elastomer material.

The present invention provides a seal element made in an elastomeric composite, said material comprising an elastomeric polymer and a phase change material (PCM), wherein the PCM is able to provide thermal energy to the elastomeric polymer upon cooling to the phase transition point of the PCM.

The invention aims to provide an addition curable silicone resin composition with excellent interfacial adhesion properties, storage stability and transparency. The addition curable silicone resin mixtures has a refractive index of 1.35 to 1.45 and includes a silicone compound having at least one group of the following formula: ##STR00001##

An object of the present invention is to provide a photocurable resin composition having excellent thick-film curability and further excellent storage stability, and a cured product of the photocurable resin composition has a high concealing effect.

The present invention is a photocurable resin composition containing components (A) to (E): a component (A): a leuco dye; a component (B): a photoacid generator; a component (C): a radical polymerizable compound (except for a (meth)acrylate having a tertiary amine skeleton); a component (D): a photoradical polymerization initiator; and a component (E): a tertiary amine compound.

The invention relates to a one-part, foamable hot melt gasket sealant. The foamable hot melt adhesive comprises greater than about 35 wt % of a rubber block copolymer, a tackifier and less than about 5 wt % of a wax. The foamable hot melt adhesive can be applied onto a space in between two mating surfaces without expensive foam-in-place equipment. The foamable hot melt gasket sealant is particularly suitable in automotive applications, electrical component and technical lighting sectors.
