1. Product Overview

This aliphatic high-strength one-component solvent-based polyurea waterproof coating is formulated with modified resin, special latent curing agent, and ester solvents. Triggered by ambient temperature and humidity, the product undergoes polymerization to form an elastic waterproof membrane, exhibiting excellent adhesion to substrates such as concrete, natural stone, ceramic, mortar, masonry structures, steel structures, and epoxy coatings. It offers superior waterproofing and impact-abrasion resistance. With easy application, it is widely suitable for spillways, overflow channels, dam surfaces, expansion joints, construction joints, and other scenarios.

2. Performance Features

High thixotropy and low viscosity for excellent constructability
High-strength mechanical properties and impact resistance for demanding load environments
Excellent impact-abrasion and chemical corrosion resistance for strong water flow and chemical erosion scenarios
Long gel time and short surface-dry time for multi-coat application

3. Application Fields

One-component design for ready-to-use application. Mainly used in hydraulic engineering, industrial workshops, factory buildings, civil residences, etc., especially suitable for waterproofing, seepage control, and corrosion protection in hydraulic environments such as dam projects.

5. Substrate Preparation Requirements

5.1 General Preparation

All substrates shall be surface-treated by grinding, sandblasting, or shot blasting to ensure cleanliness, soundness, and freedom from oil and loose layers.

5.2 Concrete Substrate

Remove loose surface layers to expose a sound base, requiring dryness (moisture content <6%), no dampness, and free from standing water. Plug holes with special repair putty and apply compatible primer before coating.

5.3 Steel Substrate

Sandblast or shot blast to Sa2.5 standard, thoroughly remove dust, and apply compatible primer.

5.4 Other Substrates

For special substrates, please consult Wanhua Energy Saving Technology Department in advance.

6. Construction Environment Conditions

Temperature Range: 5-35°C, substrate temperature shall be at least 3°C above the air dew point temperature
Humidity Control: Ambient humidity ≤80%RH, concrete substrate moisture content <6%
Ventilation Requirement: Ensure good ventilation at the construction site, avoid strong wind to prevent dust contamination and affect coating compactness

7. Application Methods

Support multiple application methods including brush coating, roller coating, and spray coating, flexible to project requirements.
