Abstract
A composition useful as a parting agent for concrete formwork is provided. The composition comprises water; a completely or predominantly unsaturated fatty alcohol containing 6 to 22 carbon atoms and with an iodine value of 40 to 200; and an alkyl or alkenyl oligoglycoside having an alkyl or alkenyl group containing 4 to 22 carbon atoms, a sugar unit containing 5 or 6 carbon atoms and a degree of oligomerization of 1 to 10. The parting agent is particularly storage-stable at low temperatures.
Claims17
A water-based concrete parting agent, comprising:
- (a) a fatty alcohol corresponding to the formula
- R1OH (I)
- wherein R1 is a completely or predominantly unsaturated hydrogen radical containing from 6 to 22 carbon atoms and having an iodine value of from 40 to 200, said fatty alcohols present at from 10 to 50% by weight based on the parting agent;
- and
- (b) an alkyl or alkenyl oligoglycoside corresponding to the formula
- R2O-[G]p (II)
- wherein R2 is an alkyl or alkenyl group containing 4 to 22 carbon atoms, G is a sugar unit containing 5 or 6 carbon atoms and p is a number of from 1 to 10, said alkyl or alkenyl oligoglycosides present at from 0.2 to 5% by weight based on the parting agent.
