摘要： A composite panel comprises first and second metallic sheets each having an inner and outer surface, a silicone-based primer coating on the inner surface of the first and second metallic sheets and an organosilicon adhesive contacting the primer coating on both the first and second metallic sheets, wherein the adhesive has a gross heat of combustion (Q-PCS) of no greater than 1.4 MJ/m2. The panel is compliant with specification EN 13501-6:2018, classification A1.

摘要： A one-component toughened epoxy-modified polyurethane and/or urea adhesive includes a mixture of dicyandiamide and a dihdyrazide as curing agents. The mixture of curing agents permits the adhesive to be cured at lower temperatures while developing good adhesive and mechanical properties in the cured adhesive.

摘要： Moisture-curable, one component adhesives contain an isocyanate-terminated prepolymer, a low molecular weight polyisocyanate compound, a hydrolysable mercaptosilane, a urethane catalyst and a carbon black filler. The adhesives exhibit an excellent combination of high modulus, excellent hydrolytic and heat stability, and high sag resistance.

摘要： A method for visualizing biofilm on a solid surface. The method comprises steps of:
(a) providing a solid surface which has been in contact with an aqueous medium and at least a portion of the solid surface potentially is covered with biofilm, (b) maintaining the solid surface in a horizontal position and covering the solid surface with an aqueous dispersion of carbon particles, (c) tilting the solid surface at an angle of at least 5° from horizontal to allow excess aqueous dispersion of carbon particles to flow from the surface, (d) detecting any biofilm present on the solid surface by determining whether there are areas not covered by aqueous dispersion of carbon particles.-

摘要： Adhesive bonds are applied by mixing two adhesives with different properties and dispensing them to form bondlines between substrate pairs. The adhesives are then thermally cured and cooled. Varying the mix ratio permits one to vary the properties of the adhesive mixture so formed for use in bonding many different substrate pairs. The process allows potentially infinite variations of adhesive properties between those of the respective starting adhesives, simply by varying the mix ratio. The invention is especially adapted for use in manufacturing settings in which adhesives are to be applied in multiple places, but differing adhesive properties are needed among the various bonding areas.

摘要： An article has a can with a valve stem and a dispensing device, the dispensing device includes a cap over the valve stem, a hollow tube extending through a slot in the cap and attached to the valve stem, a sleeve slidably extending over the hollow tube, a lever hingedly attached to the cap and operatively engaging the sleeve, an elastic feature that provides a force or causes a force to be applied to the sleeve in a direction that tries to move the sleeve to a closed position, and a sealing gasket between the sleeve and hollow tube proximate to the exit end of the hollow tube; where the sleeve seals the hollow tube when in the closed position and displacing the lever towards the can simultaneously unseals the hollow tube and tilts the valve stem, and when released allows the sleeve to restore to a closed position.

摘要： An article comprises a tube having peripheral areas, including an upper section, a lower section, an inner section, and an outer section, the tube further comprising a tube wall having an inner layer and an outer layer, the inner layer being a semipermeable membrane that is permeable to vapors but impermeable to liquids and the outer layer being a nonwoven fabric, and the tube further comprising at least one inlet port integrated into the tube wall to permit the flow of an activated or activatable foamable composition into the tube interior, wherein the tube further has a plurality of holes that penetrate through the inner and outer layers of the tube to allow expanding foam to both fill the interior of the tube and exit the tube and fill a space exterior to the tube.
