An adhesive composition for use in flooring applications that includes a moisture curable polymer system; a calcium carbonate filler system having a first spheroidal particle of calcium carbonate having an equivalent spherical mean diameter of 70 nanometer (nm) to 15 micrometer (μm) and a second spheroidal particle of calcium carbonate having an equivalent spherical mean diameter of greater than 15 μm to 200 μm; a seed oil based fatty acid ester; and a silane based adhesion promoter. The adhesive composition provides low viscosity along with high shear resistance, which helps to retain the troweled ridges to enable maximum coverage.

Moisture curable adhesive compositions

A curable resin composition comprising: (1) a urethane (meth)acrylate; (2) a reactive diluent selected from the group consisting of i) a hydroxyl alkyl (meth)acrylate monomer where the acrylate group, which is attached to the carbonyl group, is attached to a hydrogen or a methyl group and the carbonyl group is attached to the hydroxyl group thru an R2 alkylene group containing 2 to 18 carbon atoms per molecule.

Styrene-free reactive diluents for urethane acrylate resin compositions

A process for making a curable resin composition comprising the steps of: (1) reacting a) an isocyanate; and b) a polyol mixture with a bimodal distribution of i) a first polyol mixture comprising polyols having an average equivalent weight of from 50 to 400; and ii) a second polyol mixture comprising polyols having an average equivalent weight of from 1000 to 5000 to form a urethane prepolymer; and (2) adding a capping agent to the urethane prepolymer to form the curable resin composition.

Process for making urethane acrylates

Moisture-curable resin compositions include a mixture of one or more polysilylated of ethers and one or more polyether monosilanes. The polyether monosilanes have one hydrolysable silane group per molecule, and the hydrolysable silane group has at least two hydrolysable substituents. The polyether monosilane is an effective plasticizer and viscosity reducer. Despite the presence of the polyether monosilane, the resins compositions cure to form cured sealants having useful tensile and elongation properties.

An isocyanate-functional silicone-polyether copolymer having a particular structure is disclosed. A method of preparing the isocyanate-functional silicone-polyether copolymer is also disclosed, the method comprising reacting a polyether compound and an organosilicon compound to give the isocyanate-functional silicone-polyether copolymer. A silicone-polyether-urethane copolymer formed therewith, as well as a method of preparing the silicone-polyether-urethane copolymer, are also disclosed. Sealants comprising the isocyanate-functional silicone-polyether copolymer and/or the silicone-polyether-urethane copolymer are further disclosed.

A silicone-polyether copolymer has the formula X&#x2014;Y, where X is a silicone moiety having a particular structure and Y is a polyether moiety. An isocyanate-functional silicone-polyether copolymer formed therewith is also disclosed. Further, a silicone-polyether-urethane copolymer formed with the isocyanate-functional silicone-polyether copolymer is disclosed. Related methods of preparation as well as sealants and cured products thereof are further disclosed.

The instant invention provides a curable formulation suitable for laminating adhesive applications, and laminating adhesives made therefrom.

Laminating adhesive&#x2014;polyester-polycarbonate-polyol systems

Polyester-co-carbonate polyols and methods for producing the same are provided. The method comprises reacting one or more alcohols having an OH functionality of two or more with one or more organic diacids to form a reaction mixture, adding a first amount of dialkyl carbonate to the reaction mixture to remove water remaining from the reaction mixture by azeotropic drying, adding a transesterification catalyst to the dialkyl carbonate containing reaction mixture and adding a second amount of dialkyl carbonate to the catalyst containing reaction mixture.

Single-pot process for the production of polyester-co-carbonate polyols

Embodiments of the invention provide for methods of producing a polycarbonate polyol. The method includes charging a vessel with butanediol, charging the vessel with a polymerization catalyst, and adding to the vessel dimethyl carbonate at a rate of at least 2.0 g of DMC per minute per kg of BDO to produce polycarbonate polyol at a polycarbonate polyol yield of at least 80% of a theoretical yield.
