摘要:
A method for producing a floor by casting a concrete slab with a concrete composition having a water/cement ratio of 0.4-0.7 and a minimum compressive strength no lower than 10 MPa, and depositing a first covering layer on the freshly cast concrete slab as soon as the slab is capable of bearing the weight of a man walking thereon without being damaged, or once the compressive strength of the slab concrete has reached a value of 0.15-0.4 kg/cm2. Said covering layer is based on a self-levelling composition. The method is useful for producing all kinds of floors for indoor, outdoor, industrial or commercial use.
摘要:
A process of bonding different constituent materials of different tensile strengths in a single step in an isostatic high pressure reactor in order to produce a composite material.
摘要:
Copolymer dispersions containing polyamide segments in aqueous media form binders for coatings for various industrial and construction materials. The copolymers have a high percentage of amide linkages. The copolymers are linked into higher molecular weight species by reactions with polyisocyanates (which forms urea linkages if the other reactant is an amine or a urethane linkage if the other reactant is a hydroxyl group).
摘要:
A product that includes a cement-based substrate, a first coating, and a topcoat powder coating layer is described. Also described is a method of making a product that includes providing a cement-based substrate, applying a first coating, and applying a topcot powder coating layer. Also described is a method of making a product by providing a pre-primed or pre-sealed cement-based substrate and applying a topcoat layer including a powder coating.

摘要:
Radiation-curable coating compositions for a surface such as a concrete floor, which include at least one multi-functional monomer or oligomer, at least one photoinitiator, at least one glossy band matting agent, and at least one matte band matting agent are described and claimed. These low gloss coating compositions allow for application of the coating composition over an area larger than a UV radiation source, while minimizing the formation of gloss bands or gloss lines that exhibit a different level of gloss in the areas where light leakage from a side light shielding of the UV radiation source results in a very weak radiation intensity, as compared to the areas subjected to high radiation intensity. These low gloss coating compositions are optionally clear topcoat compositions. In addition, a method for coating a surface with a radiation-curable coating composition that results in a cured surface with minimal differences in gloss exhibited following curing by a UV radiation source, and a surface coated with the radiation curable coating compositions of the instant claimed invention are described and claimed.
摘要:
L'invention se rapporte à un procédé pour recouvrir de manière uniforme, par au moins une couche d'un matériau plastique, la surface interne et/ou externe d'un corps creux ou bien la surface externe d'un corps plat en verre ou en matière poreuse telle que la céramique, consistant à chauffer ledit corps creux ou ledit corps plat à la température de ramollissement du matériau plastique, puis à appliquer le matériau plastique sur ledit corps chauffé, à l'aide d'un lit fluidisé. Ce procédé se caractérise en ce qu'il consiste à effectuer un nettoyage thermomécanique préliminaire de ladite surface lors du chauffage de ladite surface. L'invention se rapporte aussi aux corps creux ou plats susceptibles d'être obtenus selon le procédé.
