HZ06 Polyaspartic Waterproof Topcoat

PRODUCT OVERVIEW

HZ06 is a colored, two-component solvent-free polyaspartic polyurea elastomer topcoat formulated with high-performance polyaspartic ester resin, nano-functional materials, ultra-fine pigments and fillers, and performance additives. The cured coating provides long-lasting waterproofing, corrosion resistance, high strength, strong adhesion, flexibility, weather resistance, anti-yellowing performance, and long service life.

KEY FEATURES

• Long-term waterproof and weather-resistant protection
• High strength with strong substrate adhesion
• Good flexibility and impact resistance
• Excellent anti-corrosion and anti-rust performance
• Good resistance to yellowing for indoor and outdoor use
• Solvent-free, two-component system
• Suitable for roller or trowel application

APPLICATION SCOPE

• Roofs, balconies, and exposed building surfaces
• Swimming pools, bathrooms, and shower areas
• Indoor and outdoor cement and concrete substrates
• Waterproof renovation over tiles, marble, and paving slabs
• Protective and anti-corrosion coating for metal substrates

TECHNICAL SPECIFICATIONS

INDEPENDENT TEST HIGHLIGHTS

Independent testing to GB/T 22374-2018 confirmed compliance with the Type W requirements for container condition, coating-film appearance, drying time, and initial flowability. Test results included a surface-dry time of 3 hours, full-dry time of 24 hours, and initial flowability of 188 mm at an A:B mass ratio of 2:1.

PACKAGING AND MIXING

• Packaging: 8 + 4 kg/set (Component A + Component B)
• Mixing ratio: A:B = 2:1 by weight
• Working time after mixing: within 20 minutes
• Application: roller coating or trowel application

APPLICATION GUIDELINES

1. Surface preparation: Grind, repair, and level the substrate as required. The surface must be flat, dry, clean, and free from dust, chalking, oil, and standing water.
2. Primer application: Apply one uniform coat of the recommended HD400 or HD300 primer at approximately 0.1 kg/m². Allow 2-4 hours, or until dry and non-tacky.
3. Topcoat mixing: Add Component B to Component A and mix thoroughly with an electric mixer for 10-30 seconds. Use the mixed material within 20 minutes.
4. Trowel application: Apply one uniform coat at approximately 0.35 kg/m².
5. Roller application: Apply two coats at a total consumption of approximately 0.5 kg/m². Allow at least 2-4 hours between coats and confirm the first coat is non-tacky.
6. Curing: Protect the finished surface from traffic, heavy objects, rain, and standing water. Maintain good ventilation and cure for at least 24 hours before opening to traffic.

PRECAUTIONS

• Both primer and topcoat are two-component materials and must be mixed thoroughly before use.
• The substrate must not be damp and must not contain standing water, otherwise blistering may occur.
• Avoid application during rain, snow, or high-humidity conditions.
• Keep the coating away from water until it has developed sufficient strength.
• For indoor work, maintain good ventilation. Normal application odor typically dissipates within 3-5 days.
• At low temperatures, extend the curing period to 1-2 days according to site conditions.

STORAGE AND TRANSPORTATION

• Store sealed in a dry, well-ventilated warehouse at 5-35 °C.
• Protect from water, direct sunlight, fire, heat, and freezing.
• Shelf life: 6 months from the production date under recommended storage conditions.
• Transport in accordance with applicable regulations and protect from severe cold, rain, and sunlight.
