Abstract: An improved handheld applicator is provided, fitted into an assembly onto a pressure container which is equipped with a gun valve and containing a viscous compound suitable for forming a silicone paste, a polyurethane (PU) foam, or a glue, the applicator being producible in one single injection molding step and providing in handheld use the ergonomics, the aiming and the dosing accuracy comparable to the use of the pressure container with a dispensing gun. Further provided is a process for the production of the applicator and of the assembly, as well as the use of the assembly for applying a compound from the pressure container with a handheld method.

Abstract: Disclosed is a polyurethane foam composition based on polyisocyanates comprising initially at least 20 wt % mMDI and at most 24.5 wt % mTDI, a towards isocyanate polyfunctional and a towards isocyanate monofunctional compound, which composition contains a) less than 1.00 wt % residual free mMDI, b) at least 0.4 wt % total of mMDI of which at least one isocyanate group has been reacted with a monofunctional compound, c) wherein the polyurethane prepolymer composition is having an isocyanate index of at least 105 and at most 350, d) wherein the equivalents ratio of functional groups of the monofunctional compounds relative to the amount of the isocyanate functional groups initially present is at least 6.5%, and e) wherein the equivalents ratio of towards isocyanate tri- and higher functional reactive compounds relative to the isocyanate functional groups initially present is at most 6.50%. Further disclosed is a suitable prepolymer, production methods and uses.

Abstract: An improved coupling piece for the Click-and-Fix coupling of a disposable pressure container with a dispensing gun is provided, including an integrated cap and internal support legs for securing the position of the stem of the valve of the container when pressure increases inside the container, and which coupling piece may be produced as one single product using injection moulding. Further provided is an assembly of a container with the coupling piece, and a process for producing the coupling piece and the assembly. The coupling piece and/or the assembly may be further adapted for handheld use with a suitable handheld applicator.

Abstract: A dual purpose coupling piece is provided for on the one hand the screw coupling of a disposable pressure container with a dispensing gun, and which further includes means for on the other hand also cooperating in a bayonet-type coupling with a suitable handheld applicator for application of the compound as in the handheld use. A suitable handheld applicator is also provided. The coupling piece and/or the handheld applicator may be designed for the production as one single product using injection moulding. Further provided is an assembly of a container with the coupling piece, and a process for producing the coupling piece and the assembly, as well as the handheld applicator.
