- data
- NR POLY.pdf
NR POLY 73 is a non-yellowing polyaspartic flooring paint that has high impact resistance, resistant to fading and less discoloration thanks to UV resistance. NR POLY 73 can be manually painted using brush and roller without corresponding spray equipment. It is resistant to scratching, abrasion, water, fast drying, long lasting and glossy, so it is suitable for floor coating topcoat.

how to use
- Surface treatment
- 1. Completely remove oil, moisture, sand, dust, and other foreign matter from the surface to be coated.
2. Cure concrete for at least 28 days at a temperature of 21℃ and a relative humidity of 60%.
3. Remove the protruded parts using a grinder. Cracks on the surface should be repaired before coating. - Coating method
- ▷Primer : Epoxy(It may vary depending on the substrate)
▷Intermediate coating: Epoxy
▷Top coat : Polyaspartic - Coating conditions
- 1. Atmosphere Temperature: 5~35℃, Surface Temperature: 40℃ or below, Relative Humidity: 80% or less.
