Abstract: The present disclosure relates to a novel cross-linking compound and a polymer using the same. More particularly, the present disclosure relates to a novel cross-linking compound that does not cause thermal decomposition at one end and thus prevents in advance the generation of volatile substances and decomposition products, and a polymer prepared using the same.

Abstract: The present invention relates to a 3D printing resin comprising a monomer or oligomer having at least one acrylate or methacrylate subunit and an initiator. The 3D printing resin is characterized in that it comprises a saturated fatty acid or a carboxylic acid ester, whereby a separation effect is achieved with respect to other plastics. The invention further relates to a polymer comprising the monomers and oligomers described above in polymerized form and a saturated fatty acid or carboxylic acid ester. If only 60-80% of the double bonds of the monomer or oligomer are reacted, a green compact can be obtained. The invention also provides a kit-of-parts system comprising the above-described 3D printing resin for producing a polymer with a separation effect and a powder component and a liquid component for producing a plastic. Finally, the invention also relates to methods for producing a molded part with a separation effect and to a method for producing a molded part, wherein the molded part is complementary to another molded part. In the latter method, one molded part is made from the 3D printing resin described above and the other molded part is made from a plastic.

Abstract: Benzyl ether-type phenolic resins are useful in either a phenolic resin polyurethane cold-box (PUCB) process or a phenolic resin polyurethane no-bake (PUNB) process. The benzyl ether-type phenolic resins contain at least one formaldehyde scavenger in the form of a beta-dicarbonyl compound, and an alpha-carbonyl-carboxyl compound, particularly glyoxylic acid, binders based on these phenolic resins, and isocyanate compounds having at least two isocyanate groups. The resins having the inventive concept exhibit low free formaldehyde content. The inventive concept extends to molding material blends containing the binder, and a method for producing cores, molds or risers.

Abstract: Described herein is a manual process for injection molding of coated components, more particularly coated soles of plastic, where first of all the molding tool is lined with a release agent composition and, after flashing of this release agent composition, a composition for forming the component is injected. After crosslinking of these two compositions, the produced coated component is removed from the molding tool and subjected optionally to an aftertreatment.
