A method is disclosed for preventing hardener compounds to be formed from hardener precursors in a sealed and pressurized aerosol can. This includes a paint forming dispersion containing after sealing the can a liquefied propellant, epoxy or/and polyurethane resins amount W1, hardener precursor of the epoxy or/and polyurethane resins amount W3, where the epoxy or urethane hardener precursors are selected from a group including an imine, an enamine, a Mannich base, a Schiff's base, an oxazolidine, an aldimine and mixtures thereof, free water of amount W1 in a range of 1-10000 ppm, and brought into the can alongside with the other paint dispersion forming chemicals before sealing the can. A catalytic compound prevents formation of the epoxy or/and polyurethane hardener amines from the epoxy or/and polyurethane hardener precursors:

A pressurized spray system is disclosed which includes a sealed container and an aqueous composition disposed inside the sealed container. The aqueous composition includes an amine solubilizer, and solubilized and gaseous carbon dioxide. Aerosol paint products and methods of making such systems and products are also disclosed.

A fire protection composition contains a binder on the basis of an alkoxysilane-functionalized polymer and a liquid carbon supplier. The fire protection composition allows application in a simple and rapid manner of coatings having the layer thickness required for the particular fire resistance time, the layer thickness being reduced to a minimum while achieving a good fireproofing effect. The fire-protection composition is formulated as a multi-component system. The fire-protection composition is particularly suitable for fire protection, especially as a coating of construction elements such as steel carriers.

Building materials that include a structure such as a structural support are described, wherein the structure defines a plurality of cavities at least partially filled with a polymeric foam. The polymeric foam may include a hydrophobic polyurethane foam having a density less than 5 pcf and/or the structure may include a hydrophobic polymer.
