摘要:
Suggested is a novel coated particleof active ingredients with controlledrelease properties at pH-valuesfrom 10 to 14, wherein the active ingredient is selected from one or more construction chemical additives for the control of inorganic binders, characterized in that the coating comprises shellac, a process for its manufacture and the use thereof as an additive for mortars, dry mortars, cement slurries and/or concretes.
摘要:
A proposal is made for a cementitious system which comprises accelerator particles coated with crosslinked shellac, for the use as an additive component which comprises the accelerator particles coated with crosslinked shellac, and for a cement slurry which comprises the cementitious system and water.
摘要:
The invention relates to a powdery building material composition, preferably a factory-made dry mortar, and in particular tile adhesives, joint fillers, knifing fillers, sealing slurries, repair mortars, leveling mortars, reinforcing adhesives, adhesives for thermal insulation composite systems (TICSs) mineral plaster or render, fine knifing composition, and screed systems, containing an ester of A) 2-ethylhexanoic acid and B) an alcohol having a boiling point of at least 160°C. The invention further relates to the production of said products and to the use of the esters according to the invention in powdery building material compositions to reduce dusting.
