摘要:
The instant invention is concerned with the post-treatment of ²-hemihydrate plasters for the purpose of stabilization. The invention relies in the addition of a retardant to the calcined ²-hemihydrate. It is also the purpose of the invention to provide stabilized ²-hemihydrate plasters which exhibit advantageous properties.
摘要:
A compound according to the present invention is obtainable by reacting a polyisocyanate with a monoalkylether of a polyoxyalkylenemonoamine, in such an amount that substantially no free isocyanate groups are present in the component. The polyisocyanate itself is an adduct of two polyisocyanate molecules with one isocyanate reactive molecule chosen from the group consisting of a polyoxyalkylene diamine, a polyoxyalkylene diol, a polyoxyalkylenealkanolamine, a polyester diamine, a polyester diol and a polyesteralkanolamine, the average molecular weight of the isocyanate reactive molecule being more than 1000.
