ALFAPOL PU-3T — gloss polyurethane sealer for concrete and polymer floors
Clear gloss polyurethane sealer, resistant to ultraviolet and fading, for concrete and polymer floors.

The radon-proof KR magnesia compound is self-levelling and forms a wear-resistant, corrosion-resistant thin-layer industrial floor coating. Compressive strength is at least 50 MPa, flexural strength 8 MPa, bond strength to concrete 2 MPa, abrasion up to 0.7 g/cm², with resistance to petroleum products. The coating is non-shrink and non-combustible (NG), serviceable from −30 to +40 °C; foot traffic after 8–10 hours.
