  • Patent number: 10899080
    Abstract: A generative process for the manufacture of three-dimensional mouldings is characterized by constructing the moulding stepwise by site-specific delivery of a structure-forming material in liquid form, where a second material is additionally delivered as a supportive material into regions which are intended to remain free from the structure-forming material, and is removed once the structure-forming material has been solidified. The supportive material exhibits low shrinkage upon cooling and is particularly stable in the cooled state and further exhibits low surface roughness.

  • Publication number: 20200317923
    Abstract: An additive method of production of three-dimensional shaped bodies constructs the shaped body step by step by deploying a structure-forming material in liquid form in a location-specific manner, and additionally deploying a second material composed of wax as support material in regions that are to remain free of the structure-forming material and removing the support material after consolidation of the structure-forming material. The support material shows good dimensional stability and can be processed within a broad temperature window.

  • Patent number: 10618815
    Abstract: It is an object of the invention to provide an economically viable process for the production of hydrophobized aerogels which works both inexpensively and in a resource-conserving manner. 2.2. This object is achieved by the provision of a process for producing organically modified aerogels by producing a sol containing [SiO4/2] units and [RxSiO(4?X)/2] a units, where x may be the same or different and is 1, 2 or 3, and R may be the same or different and is hydrogen or an organic substituted or unsubstituted radical, using the sol to form a gel, surface-modifying the gel obtained in the presence of more than 0.1% by weight of a phase modifier in a mixture comprising organosiloxane and initiator, wherein the mixture contains at least 20% by weight of organosiloxane and wherein the initiator consists of acid or organosiloxane or mixtures thereof and the gels obtained are dried. 2.3. The aerogels provided can be used as insulating materials, especially in thermal insulation.

  • Patent number: 9617428
    Abstract: Metal oxides surface modified with M and D groups where the D groups are in excess relative to the M groups exhibit high rheology properties in liquid compositions and provide products with elevated mechanical properties. The modified metal oxides contain a significant quantity of unreacted silanol groups, and can be more easily incorporated into polar organic substances, and also increase physical properties of cured polymers containing the modified metal oxides.
