BLJ-643 is a kind of epoxy anti-alkali acrylic emulsion designed for solving the problem of salt-petering about concrete and cement mortar. It is copolymerized by high quality emulsifier and special functional monomer with synthesis technology. It has small particle size, suitable viscosity, good calcium ion stability, dilution stability, freeze-thaw stability, mechanical stability.

Features:
1.Alkali resistance, salt petering resistance, frosting resistance.
2.Introduced epoxy group, good adhesion to substrate and finishing.
3.Water resistance, impervious, water seepage steam which make wall breath and prevent surface paint bubbling and drumming because of the water vapor pressure.
4.Small particle size, strong base material permeability, good sealing ability. Widely used in interior and exterior wall alkali resistance primer paint, also used in sealing transparent primer.
