摘要:
A packaging unit for holding an adhesive or a component of an adhesive includes an outer container and an inner member placed in the outer container. The outer container has a generally box shape and further has a perforation around the perimeter of the container. The inner member has a spout through which the adhesive or component of the adhesive is received and dispensed. Tearing the perforation separates the outer container into a top portion and a bottom portion so that the inner member is removable from the outer container.

An adhesive composition for use in adhering insulation panels to roofing substrates and roofing membranes to the insulation panels include two components that are mixed prior to application on the roofing substrate. The first component may include a renewable polyol and catalyst. The renewable polyol is selected from any non-petroleum based polyol that is derived from a renewable source. The second component includes isocyanate, and may also include a polyol and a catalyst. The isocyanate and the polyol may each be any non-petroleum based isocyanate or polyol that is derived from a renewable source.

A two-part adhesive includes an A side, a B side, at least one of a polyurethane prepolymer and a diisocyanate, a polyol, a catalyst, and an adhesion promoter. The polyurethane prepolymer or diisocyanate is present in the A side from about 50% to 100% by weight of the A side composition. The polyol is present in the B side from about 52% to about 98% by weight of the B side composition. The catalyst is present in the B side from about 0.5% to about 5% by weight of the B side composition. The adhesion promoter is present in at least one of the A side composition and the B side composition from about 10% to about 50% by weight of the two-part adhesive. A ratio of isocyanate groups in the A side to hydroxyl groups in the B side is greater than 1.5:1.
摘要:
A spacer used to secure a solar module to a substrate having surface irregularities or unevenness includes a spacer layer located between two adhesive layers. The spacer has a thickness greater than any anticipated irregularities or unevenness on the surface of the substrate. The spacer is comprised of materials that provide sufficient strength and weatherability.
摘要:
A foamed composition adapted to seal to a substrate is provided. The foamed composition includes a radiation curable rubber, a photoinitiator, a blowing agent, a styrene-ethylene/butylene block copolymer, a light mineral oil, rheology modifier, a tackifier, and one of a radiation curable monomer and radiation curable oligomer, and wherein the composition is foamed upon application to the substrate.
摘要:
A system for applying a two-part adhesive to a substrate includes a prime mover for providing an output torque, a first pump connected to the prime mover for receiving the output torque, the first pump having an inlet and an outlet, a second pump connected to the prime mover for receiving the output torque, the second pump having an inlet and an outlet, a first compound in communication with the inlet of the first pump, a second compound in communication with the inlet of the second pump, a first accumulator in communication with the outlet of the first pump, a second accumulator in communication with the outlet of the second pump, a first manifold in communication with the outlet of the first pump, and a second manifold in communication with the outlet of the second pump. A plurality of applicators is included.
摘要:
A primer for promoting adhesion between an elastomeric adhesive and a nonporous substrate containing a silane-modified saturated polyester polymer and an adhesion promoter in an anhydrous solvent. The invention is also directed to a silane-modified saturated polyester polymer, and an adhesion promoter made by the reaction of a multifunctional isocyanate and an organosilane.
摘要:
There is provided an adhesive system comprised of a pressure-sensitive adhesive matrix having dispersed therein organic particulate solids having a particle size no greater than 300 microns, and generally no greater than 225 microns, which matrix may have at least one, and generally two, sides coated with an unfilled pressure-sensitive adhesive material, which adhesive materials generally may be acrylic materials. Such adhesive system is one generally provided as a sheet, including elongated tapes, having a thickness of from about 25 to 60 mils.
摘要:
An attachment device is adapted to permit a camera to be positively supported in various positions on a hand-held camera support. The attachment device includes a positioning structure which is slidably engaged by an adapter member secured to a camera. The positioning structure is mounted on a mounting structure which is secured to a hand-held camera support. The positioning structure is adjustable relative to the mounting structure between a horizontal position and a plurality of angular positions. Cooperating locking means on the mounting and positioning structures positively lock the latter in one of the horizontal or angular positions.
摘要:
An adhesive composition for use on a fleece-backed roofing substrate includes two components that are mixed prior to application on the fleece backed roofing substrate. The first component includes renewable polyol, catalyst, fumed silica, and surfactant. The renewable polyols are selected from any non-petroleum based polyol that is derived from a renewable source. The second component includes isocyanates, including renewable and non-renewable isocyanates.
