Elakor-PU Matte Varnish
one-component PU Matte one-component, moisture-curing varnish.
Purpose.
One-component Matte varnish Elakor-PU is used to change the gloss (mattification) of polyurethane and epoxy paint coatings, polymer self-leveling floors, protective polymer impregnations.
Advantages.
To obtain a matte shine, it is enough to apply one layer of varnish with a consumption of 80-100 g/ m2 .
Application of a second layer is allowed.
