Joint filler based on alpha hemihydrate, ready to use, two-parts (2001)(German) A two part joint compound which sets by hydration of calcium sulfate hemihydrate to gypsum. One part includes a thickener, the calcium sulfate hemihydrate, along with a non-calcium bearing phosphate set preventer. It contains water, but remains unset for at least 18 month. The second part is the set initiator. Hrsg.: Andrea Glatthor
Joint Filler with cellulose fibers and a lot of redispersion powder (1989)(German) For a joint filler consisting of gypsum, an elastic vinyl acetate/ethylene copolymer, pressure-resistant hollow microbeads of silicate glass, cellulose fibres, fillers and auxiliaries such as adhesion promoters, water-retention agents, consistency regulators and setting-time regulators for filling joints in gypsum board panels without reinforcing strips, the point of the invention is a tailor-made combination of plastic, CaSO4 hemihydrate and fibres. As a result, the strength and elasticity of the filled, hardened joints without reinforcing strips change only insignificantly as compared to the jointing with reinforcing strips according to the prior art.

Joint Filler based on alpha-hemihydrate (1987)(German) Joint filler formulation based on alpha hemihydrate, fine grain calcium carbonate, 0.1 to 0.4% by weight of an alkaline salt of carbonic acid, 1.5 to 2.0% by weight of a thickener in the form of starch ether, 0.3 to 0.6% by weight of a water-retention agent in the form of methylcellulose, 2.5 to 5.0% by weight of a mixture of a vinyl polymer and polyvinyl alcohol in the form of a dispersion powder, 0.5 to 2.5% by weight of fibres and an accelerator/retarder combination as well as small quantities of gelifying agent and a polyelectrolyte.

Joint Filler based on alpha-hemihydrate (1995)(German) The joint filler comprises alpha hemihydrate, methylcellulose, starch ethers, polyvinyl alcohol, cellulose fibres, ground limestone and mica, and also a vinyl acetate-ethylene copolymer and/or a vinyl acetate-vinyl versatate copolymer and also flocculants, accelerators and retarders. The mineral mixture of alpha hemihydrate, ground limestone and mica is milled to a particular particle size distribution. Together with the synthetic polymer component this gives a joint filler which, as a result of its behaviour, has very good processability, non-sag properties and excellent joint strength.
