HS800D has high reactivity,could spray forming on curved,slope and vertical surface without sagging.Resistant to acid,alkali,salt mist,oil,moisture,weather changes and other chemicals,no creaking,peeling,powering when long term use in damp place,no harm to environment during application.
Product Introduction
HS800D is a 100% solids, two-component spray polyurea coating specially developed for waterproof and protective applications in landfill facilities.
Based on fast-reacting polyurea technology, HS800D forms a seamless and flexible protective membrane after spraying. The coating provides excellent waterproofing, chemical resistance, impact resistance and aging resistance, helping protect concrete structures from moisture penetration and environmental exposure.
With high flexibility and strong adhesion, HS800D can adapt to minor substrate movement and deformation while maintaining long-term protection performance.
Core Functions of HS800D
Reliable Waterproof Barrier Protection
HS800D creates a continuous, joint-free coating layer that effectively prevents water penetration and reduces leakage risks in landfill structures.
The seamless membrane design provides improved protection compared with traditional coating systems that may have weak points at joints or connections.
Chemical Resistant Protection
Landfill environments may contain various corrosive substances generated during waste treatment. HS800D provides resistance against:
- Acid exposure
- Alkali environments
- Salt solutions
- Oil contamination
helping maintain structural protection under demanding conditions.
Flexible Protection Against Cracks and Deformation
With excellent elongation performance, HS800D maintains coating integrity when substrates experience minor cracks, movement or deformation. This flexibility helps improve the durability of waterproof protection systems.
Impact and Abrasion Resistance
The tough elastomeric coating structure provides excellent resistance to mechanical impact and surface wear, ensuring reliable performance during long-term operation.
