PS700G Polyurea Waterproofing Material for Anti-Corrosion Protection

Product Overview

PS700G is a spray-applied polyurea waterproofing material and protective coating designed for anti-corrosion applications in industrial and infrastructure projects.

It forms a seamless, highly elastic membrane with strong adhesion to concrete and steel, providing long-term protection against water ingress, chemical attack, and mechanical wear. With 100% solid content and ultra-fast curing, PS700G allows continuous spraying and rapid return to service, making it especially suitable for projects where downtime must be minimized.

Why Choose PS700G Polyurea Coating

In many real-world environments, traditional coatings fail due to cracking, slow curing, or weak bonding. PS700G is engineered to overcome these limitations.

• Seamless spray application – eliminates joints and leakage risks
• Rapid gel time (8–10 seconds) – significantly reduces project downtime
• High elasticity (elongation up to 470%) – adapts to structural movement
• Strong adhesion to concrete and steel substrates
• Excellent resistance to abrasion, impact, and chemicals
• Stable performance under temperature variations

This makes PS700G a reliable solution for long-term protection in demanding environments.

Applications of Spray Polyurea Waterproofing Material

PS700G is widely used in projects requiring both waterproofing and corrosion resistance:

• Infrastructure: bridges, tunnels, sewage systems
• Industrial flooring and secondary containment areas
• Steel structure and storage tank protection
• Marine and offshore environments
• Roof waterproofing systems
• Power plants and chemical facilities

It is particularly suitable for large-scale or fast-track construction projects.

Technical Data of PS700G Polyurea Coating

Physical & Mechanical Properties
