Solid-color rubber emulsion · elongation ≥500%
Rubber Waterproof Coating
YR-9(8)804-04
1 / 4
YRong solid-color waterproof coating based on synthetic rubber emulsion with elastomers, impermeability aids, and UV absorbers. High elastic crack resistance (elongation ≥500%), strong weather and water resistance, and low VOC—for roofs, basements, bridges, and tunnels.
Uses SBS / APP / neoprene-type rubber emulsions with polymer elastomers to form a highly elastic, weatherable waterproof membrane through physical cross-linking and chemical curing—built to absorb substrate movement and keep water out.
