Abstract
A two-component composition including a first component A including an aqueous dispersion of at least one polymer P, at least one metal salt M, and at least one liquid organic freeze point depressant D, and a second component B having a mineral binder composition C having at least one hydraulic binder H. The two-component composition is used as an adhesive, sealant or coating and to a method for bonding a first substrate to a second substrate.

A two-component composition comprising:
- a first component A comprising:
- a1) an aqueous dispersion of at least one polymer P,
- a2) at least one metal salt M, and
- a3) at least one liquid organic freeze point depressant D, wherein the liquid organic freeze point depressant D is a polyhydric alcohol selected from the group consisting of erythritol and pentaerythritol, and
- a second component B comprising:
- b1) a mineral binder composition C comprising at least one hydraulic binder H and
- b2) optionally at least one cement hydration retarder R,
- wherein the at least one liquid organic freeze point depressant D comprises 0.5-4.5 wt. % of the total weight of the first component A.
