Aliphatic Spray Polyurea Waterproofing Coating PS700F

Product Overview

PS700F is a high-performance aliphatic spray polyurea waterproofing and protective coating developed for demanding industrial and infrastructure applications.

Unlike conventional waterproof coatings, PS700F combines excellent UV resistance, long-term weatherability, and strong waterproofing performance with high mechanical strength. Its seamless membrane forms a continuous barrier that prevents water penetration, corrosion, and substrate degradation.

With its high elasticity and fast curing properties, PS700F is suitable for complex surfaces, vertical structures, and large-scale industrial projects requiring durable waterproof protection.

Key Features

• Excellent waterproofing and moisture barrier performance
• Outstanding UV resistance and long-term weather stability
• Superior chemical resistance (acid, alkali, salt, oil)
• High elasticity with crack-bridging capability
• Seamless, joint-free protective membrane
• Strong adhesion to concrete and steel substrates
• High abrasion and impact resistance
• Fast curing for efficient application
• Suitable for harsh industrial and marine environments

Typical Applications

• Concrete roofs and waterproofing systems
• Industrial flooring and protection layers
• Bridges and infrastructure projects
• Water tanks and containment structures
• Marine and coastal facilities
• Underground structures and tunnels
• Steel structures exposed to moisture and corrosion

What Is Aliphatic Spray Polyurea Waterproofing Coating Used For?

Aliphatic spray polyurea waterproofing coatings are used to protect structures from water penetration, UV degradation, and environmental corrosion.

PS700F is designed to provide long-lasting waterproof protection for both concrete and steel surfaces, especially in environments exposed to moisture, chemicals, and outdoor weathering.

Why Choose PS700F Over Conventional Waterproof Coatings?

Compared with traditional waterproof materials such as acrylics, bituminous coatings, or polyurethane systems, PS700F offers:

• Seamless membrane without joints or weak points
• Much faster curing and installation efficiency
• Higher durability under mechanical stress
• Superior UV resistance and color stability
• Longer service life in harsh environments
