Application Areas
BH-PU-2025 is primarily used as an exterior waterproof transparent polyurea main agent, suitable for waterproofing and decorative coatings of various building facades, ensuring both aesthetic appeal and long-term structural protection. Specific applications include:

· Transparent Waterproof Coating for Facades: Suitable for the exterior wall coatings of various buildings, providing a transparent effect that maintains the original appearance while offering strong waterproof and anti-aging properties.

· Decorative Waterproof Coating: Ensures long-lasting stability of waterproof performance while maintaining the building's aesthetic, applicable to the exterior walls and decorative surfaces of commercial and residential buildings.

· Other Transparent Polyurea Waterproof Systems: Can be used in any scenario requiring transparent, flexible waterproof coatings, such as sunrooms and glass curtain walls.

Product Advantages

· Durable Waterproof Protection: BH-PU-2025 offers strong waterproof performance, effectively preventing moisture from entering the building structure, extending the lifespan of exterior walls, and avoiding water penetration and structural damage.

· High Transparency, Preserving Original Aesthetics: Due to its transparent liquid characteristics, the waterproof layer formed after curing is nearly invisible and does not affect the building's appearance, making it ideal for decorative exterior waterproofing needs.

· Superior Flexibility and Strong Adhesion: The cured polyurea coating not only has excellent flexibility to withstand thermal expansion and contraction but also possesses strong adhesion, ensuring the coating does not peel off over time.

· Environmentally Friendly Materials, Safe and Reliable: With over 96% active content, it reduces the release of volatile organic compounds (VOCs), meeting environmental standards, and is suitable for projects and buildings with strong environmental awareness.

Usage Recommendations

· Construction Environment Requirements: It is recommended to carry out construction in environments above 5°C, avoiding extreme weather conditions that could affect the results. In high-temperature or humid environments, appropriate measures should be taken to ensure stability in gel time and curing effects.

· Construction Steps: Mix thoroughly before application to ensure uniformity, and apply immediately after mixing. Complete the coating within the 60-minute gel time to ensure consistency and waterproof effects.

· Storage Conditions: Store in a dry, cool place, avoiding direct sunlight and high-temperature environments. It is advisable to keep the product sealed before use to maintain optimal performance.
