TEKNOPUR 300-800 is a two-pack, solvent-free elastomeric coating. Coating is applied by spraying. TEKNOPUR 300-800 is based on pure polyurea.
Intended for use as waterproofing for bitumen roofs and concrete structures and as a coating for surfaces which require abrasion resistance e.g. transport wagons.
TEKNOPUR 300-800 withstands impacts, hard abrasion, chemicals and constant immersion in water. It will cure also in -20°C temperature. Coating yellows due to the impact of UV-light. When a surface with good colour retention is desired, the surface needs to be overcoated with e.g. TEKNODUR polyurethane top coat. The coating is usually applied to 500 - 3000 µm thickness. Fire resistance class Efl for floorings. Available also a fire-retardant version TEKNOPUR 340FR. For objects subjected to chemical immersion using colour Light grey is recommended.
