aqueous coating agent composition for radon reduction method for manufacturing thereof and method of reduction of the concentration of radon

摘要

(A) 1 to 30% by weight of an adsorption-functional oligomer comprising cyclodextrin as a main component; (b) 1 to 10% by weight of propylene glycol; (c) 1 to 10% by weight of ethanol; (d) 1 to 3% by weight of an additive comprising a thickener, defoamer, and dispersant; And (e) a residual amount of water. The present invention also relates to a radon reducing method.Also, since the water-based coating agent according to the present invention is transparent, it can be easily applied in a spray coating method without affecting the appearance of building materials, and can be widely used for substrates requiring radon reduction.
