UV-Resistant Aliphatic Spray Polyurea Coating

Product Overview / WUVS-2 Two-Component Spray-Applied Waterproofing Aliphatic Polyurea · UV-Resistant · Spray-Applied YURU two-component aliphatic spray polyurea coating (WUVS-2) for waterproofing and protecting surfaces exposed to sunlight. Applications include roofs, exterior concrete, steel structures, and other projects where the coating remains weather-exposed. The material is applied using professional heated spray equipment. Upon spraying, it reacts within seconds to form a continuous, flexible coating. Its aliphatic formulation renders it particularly suitable for outdoor applications where UV resistance constitutes an important project requirement. Key Product Features Built for Exposed Waterproofing Work 01 UV Resistance for Exposed Surfaces On exposed roofs and exterior structures, the waterproofing layer has to withstand regular sunlight and changing weather. WUVS-2 uses an aliphatic polyurea formulation developed for these conditions. 02 Seamless Waterproofing Spraying allows the material to cover large areas without the overlaps found in sheet membranes. It also works on vertical and curved surfaces, although joints, edges, and penetrations still need proper waterproofing details. 03 Fast Reaction During Spraying Yuru spray-applied polyurea waterproof coating has a gel time of ≤ 20 seconds, helping the coating build thickness without sagging on vertical surfaces. The quick reaction makes it practical for projects where coating application needs to move efficiently. 04 Strength and Flexibility The coating has a tensile strength of 16.2 MPa, an elongation at break of 460%, and an adhesion strength of 3.0 MPa.

Wastewater & Drainage Treatment tanks, drainage ditches and waste-management structures, subject to chemical compatibility. Sports Stands & Outdoor Areas Stadium seating tiers, outdoor stands and recreation facilities needing waterproof surface protection. Pools & Water Facilities Water parks, swimming pools and aquaculture ponds where immersion and water-contact requirements are verified. Application Suitability Exposed roofs, exterior concrete and outdoor structures where UV-resistant waterproofing and professional spray application are required. Additional Evaluation Required Permanent immersion, chemical exposure, unusual substrates and projects with specific water-contact or color-retention requirements. Installation Data Application Requirements Substrate conditions and spray settings for professional application. Substrate & Site Conditions Concrete Strength C25 or higher Concrete Moisture Below 8% Ambient Temperature 5–35°C Relative Humidity 30–80% Substrate Temperature At least 5°C above dew point Surface preparation: Concrete must be fully cured. Clean and repair the surface, level uneven areas, and prepare the required surface profile before spraying. Mixing & Spray Settings 1:1 A:B Volume Ratio 50–80°C Material Temperature Equipment Professional two-component spray equipment Before Spraying Stir Component A and B until uniform Ventilation Maintain ventilation; avoid strong winds Recoat & Curing Guidance 12 h Subsequent Work Further work can generally proceed after about 12 hours under suitable conditions. >24 h Extended Application Interval Apply the specified primer before continuing if the interval exceeds 24 hours or rain interrupts the coating work. ≥1 day Curing Period Allow at least one day of curing under normal conditions for optimum coating performance. Site Safety Professional spray application requires suitable respiratory, eye and skin protection. Follow the product safety documentation and applicable site safety procedures.

Product Support Frequently Asked Questions Answers to common questions about application, outdoor exposure and custom product development. Can YURU Spray Polyurea be applied by brush or roller? No. This formulation is made for professional, heated two-component spray equipment. It is not intended for brush or roller application. We also offer a specialized UV-resistant polyurea waterproof coating designed for application by brush or roller. Does UV resistance mean the coating will never yellow? The aliphatic formulation is developed for outdoor UV exposure. This type of waterproof coating offers good durability, resistance to aging, and resistance to yellowing. Can it be used in pools or wastewater treatment tanks? Yes. Before specifying the coating, the project team should confirm immersion conditions, water chemistry, substrate preparation and any required water-contact approvals. Can YURU develop a formulation from our reference sample? Yes. Our technical team can evaluate a customer-provided coating sample and work toward agreed performance targets. Share the reference sample, intended application, required properties and expected order quantity. The development scope and final specifications are confirmed after technical review and testing.
