Abstract: A room temperature or low temperature curable epoxy formulation including a) an epoxy component including at least one epoxy resin and b) a hardener component including at least one compound of formula (I) wherein X is a divalent hydrocarbon group, which optionally contains one or more heteroatoms, and n is 0, 1, 2 or 3, preferably 0 or 1, and/or at least one epoxy-amine adduct, which is a reaction product of the compound of formula (I) and an epoxy compound selected from at least one of a monoepoxide and a polyepoxide, as a curing agent. The compounds of formula (I) and the epoxy-amine adduct are suitable as curing agents for epoxy formulations which provide good surface properties and good cure speed, even at low temperature curing. In particular, amine blushing can be avoided or reduced to a large extent, when these curing agents are used.

Abstract: A method for manufacturing a flooring or a coating with an inlay pattern on a substrate is disclosed which includes: a) preparing one or more inlays with an inlay material by an additive manufacturing process using a digital fabricator on the substrate at a predetermined position or predetermined positions, or on a second substrate different from the substrate to be provided with the flooring or coating; and b1) applying a curable flooring composition on the portions of the substrate not covered by the one or more inlays prepared, and curing the flooring composition, or b2) preparing a flooring by an additive manufacturing process, or b3) applying a curable coating composition on the substrate and the one or more inlays, and curing the coating composition.

Abstract: A reactive resin compositions include at least one polymerizable system, at least one volatile organic compound, cyclodextrin, and optionally at least one curing agent, which are obtainable by mixing the polymerizable system with the volatile organic compound and the cyclodextrin and storing the mixture for a period of time until an equilibrium is established between the volatile organic compound and the cyclodextrin. By adding cyclodextrin it is possible to reduce the VOC emissions of corresponding reactive resin compositions significantly, the observed effect being greater than would be expected on the basis of the molar ratio of the volatile organic compound to the cyclodextrin. The reactive resin composition can thus be used advantageously in applications such as coatings and/or sealants, in which the evaporation of organic compounds should be avoided.

Abstract: An apparatus for the contact-less, interferometric investigation of a sample object (2), particularly for the determination of sample surface profiles and depth profiles of light scattering properties of the sample (2), comprises a light source (1), able to provide broadband, low-coherence light; a beam splitter (4), arranged to split up a source light beam (11) produced by the light source (1) into a reference light beam (31) and an object light beam (21), and arranged to recombine a reflected reference light beam (31?) and a reflected object light beam (21?) to a detection light beam (51); a reference mirror element (3), arranged to reflect said reference light beam (31) back to the beam splitter (4); and a one- or two-dimensional photo sensor (5), able to convert incident light of said detection light beam (51) to an electric current signal.
