Drinking Water Grade Pure Polyurea Coating PS500C

Product Overview

PS500C is a high-performance pure Polyurea Coating specifically engineered for drinking water and sanitary environments. Formed by the rapid reaction of isocyanate and amine compounds, it creates a seamless, dense, and impermeable protective layer.

Unlike conventional coatings, PS500C is fully compliant with potable water safety requirements and meets FDA 21 CFR 175.300 standards (verified by SGS), making it suitable for direct contact with drinking water systems.

With fast curing, excellent adhesion, and superior resistance to corrosion, chemicals, and water penetration, it provides long-lasting protection for critical infrastructure.

Key Features

• Certified for food-contact and drinking water safety
• 100% solids, solvent-free, odorless, environmentally friendly
• Ultra-fast curing (gel time 4–6 seconds)
• Seamless coating with no joints or weak points
• Excellent adhesion to concrete, steel, and composite substrates
• Outstanding resistance to: corrosion, chemicals (acid, alkali, salt), abrasion and impact
• Superior waterproofing performance
• Adjustable flexibility or hardness depending on application

Typical Applications

• Drinking water pipelines
• Water storage tanks
• Water treatment facilities
• Potable water reservoirs
• Swimming pools and water containment systems
• Municipal and industrial water infrastructure

What Is PS500C Polyurea Coating Used For?

PS500C is used for protecting surfaces that come into direct contact with drinking water. It provides a hygienic, non-toxic, and corrosion-resistant barrier, ensuring water quality safety while extending the service life of infrastructure.

Is PS500C Safe for Drinking Water Systems?

Yes. PS500C complies with strict potable water regulations and is certified under FDA 21 CFR 175.300 for food-contact coatings. It has also passed sanitary performance evaluations for drinking water systems, making it safe for use in water tanks, pipelines, and treatment facilities.

How Is PS500C Different from Standard Polyurea Coatings?

Unlike standard polyurea coatings that focus mainly on waterproofing or corrosion protection, PS500C is specifically formulated for hygienic and potable water environments.

Key differences include:

1. 1: Certified for food-contact safety
2. 2: Non-toxic and odor-free formulation
3. 3: Suitable for long-term immersion in drinking water
4. 4: Enhanced chemical stability without contaminating water

How Durable Is PS500C in Harsh Environments?

PS500C demonstrates excellent long-term durability:

• No corrosion or peeling after: 30 days acid, alkali, and salt exposure; 1000 hours salt spray testing
• High tensile strength (17.8 MPa) and elongation (472%)
• Strong adhesion: Concrete: 3.2 MPa; Steel: 11.5 MPa

These properties ensure reliable performance in demanding industrial and municipal conditions.
