Soudal Soudaflex PU35 Black

Description

Soudal Soudaflex PU35 The Soudal Soudaflex PU35 is an elite architectural-grade polyurethane sealant and adhesive engineered to deliver superior mechanical reliability and permanent structural seals. This one-component, moisture-curing product is a foundational solution for modern construction, addressing the critical need for flexible joints in high-traffic and structurally active environments. Constructed for maximum longevity, Soudaflex PU35 utilizes advanced polyurethane technology to create an integrated bond that resists environmental degradation. Its medium-low modulus formulation is a critical design feature, allowing the sealant to absorb significant joint movement without losing adhesion or suffering cohesive failure. Certified to ASTM C920 class 35, it provides the professional-tier quality required for the most demanding commercial and residential installations. Key Benefits: Exceptional Durability: Specifically formulated to withstand the mechanical stress of structural movement and weather exposure. Advanced Movement Capability: Class 35 rating ensures the sealant can handle expansion and contraction in critical joints. Multi-Substrate Versatility: A single, reliable solution for bonding and sealing disparate materials like masonry, metal, and wood. Durable Fitment: Provides a solid, watertight connection that remains permanently elastic after curing. Technical Specifications: Brand: Soudal Product: Soudaflex PU35 Base: Polyurethane Color: White Modulus: Medium-Low Modulus Standard: ASTM C920 class 35 Perfect For: Concrete & Masonry: Sealing expansion and contraction joints in vertical and horizontal surfaces. Roofing Systems: Providing watertight seals around penetrations and flashing. Window & Door Installation: Perimeter sealing to prevent air and water infiltration. Application Instructions: Ensure all surfaces are clean, dry, and free from dust, grease, or old sealant residues. Prepare the joint by using a suitable backer rod to control the sealant depth. Cut the nozzle at a 45-degree angle to the desired bead size. Apply the sealant steadily using a professional caulking gun, ensuring full contact with the joint sides. Tool the sealant within the open time to ensure a smooth finish and optimal adhesion. Pro Tips: Backer Rod Usage: Always use a backer rod for deep joints to prevent three-point adhesion, which can cause sealant failure. Surface Preparation: For optimal results on highly porous surfaces, consider using a primer to enhance bond strength. Curing Environment: Polyurethane sealants cure via moisture in the air; avoid application in completely dry or extremely cold conditions where curing may be significantly delayed.
