If that product fails, the entire envelope is compromised. A leading Building Envelope Systems Supplier faced this challenge when they sought to expand their product line with a high-performance liquid flashing solution.  **Their goal was clear**: deliver a product equal to or superior to competitors, while significantly improving installer safety, environmental impact, and overall system performance. They turned to Seal Bond for a collaborative, chemistry-first partnership that could help them develop, validate, and commercialize a solution that met demanding performance and industry standards   ### The Challenge The customer identified an opportunity to better support contractors working with their non-woven residential house wrap system.  **The problem?** Their existing lineup lacked a liquid flashing sealant that met modern expectations for health, safety, environmental responsibility, and substrate compatibility. While their competitors already offered liquid flashing products, the customer wanted something better. They wanted a product that was:  - Safer for installers and the environment - Strong with flexible adhesion to multiple building substrates and various house wrap materials - Chemically-aligned with hybrid technology trends (SMP: STPE/STPU) - An [AAMA-approved product](https://fgiaonline.org/product-certification/), ensuring credibility and market acceptance - Packaged to be suitable for field and factory application (20 oz. sausages and 1–2 gallon pails) After an initial discussion at a trade show, the supplier approached Seal Bond, seeking not just a product, but a partner who could help them develop and support a comprehensive system solution.   ### Our Solution Seal Bond already had an AAMA-approved [liquid-applied flashing sealant](https://seal-bond.com/_hcms/analytics/search/conversion?redirect=aHR0cHM6Ly9zZWFsLWJvbmQuY29tL3Byb2R1Y3Qvc2VhbGJvbmQ0OTA%3D&ct=SEARCH&pid=45569419&cid=167020157821&t=Zmxhc2hpbmc%3D&d=seal-bond.com&c=2&c=3&c=6&rp=1&ab=false&opcid=&rs=UNKNOWN&hs-expires=1796840544&hs-version=1&hs-signature=APUk-v4-WuWy0JD0A2vcMxYoi9D5aT7BIg). However, to ensure it met the customer’s exact requirements, extensive testing and validation were necessary. Over several months, Seal Bond worked closely with the customer through a structured development and approval process: - **Parallel testing across two separate **[**R&D labs**](https://seal-bond.com/industrial-adhesive-capabilities) to confirm adhesion, compatibility, and performance on a wide range of substrates and wraps - **Regular project update meetings** to maintain alignment and transparency - **Product integration support**, including packaging considerations and application best practices - **Development of marketing materials, installation instructions, and documentation** to support customer training and market launch Once validated, the liquid flashing product was approved and integrated into the customer’s building envelope system offering, meeting all performance, HSE, and packaging expectations.   ### Featured Product AAMA-Approved Liquid Applied Flashing Sealant: This [hybrid polymer](https://seal-bond.com/news/hybrid-polymer-adhesive-terminology) liquid flashing is engineered for air and water sealing in residential construction. It provides a durable, flexible, weather-resistant barrier around window and door openings and is compatible with a wide range of building materials. **Key Features:** - SMP hybrid chemistry (STPE/STPU) - Excellent adhesion to common construction substrates - AAMA-approved formulation - Low-odor, solvent-free, installer-friendly profile - Available in 20 oz. sausages and 1–2 gallon pails ### The Results By partnering with Seal Bond, the Building Envelope Systems Supplier successfully launched a liquid flashing sealant that enhanced both its product portfolio and its value to end-users. Key outcomes included: - **A fully approved, system-compatible liquid flashing product** that supports current and future customer needs - **Improved building performance** for homeowners by helping ensure an airtight, watertight envelope protection - **A safer, more environmentally responsible solution** that installers can trust - **Increased accessory and house wrap sales**, thanks to a more complete system offering - **A strong, ongoing partnership**, with discussions already underway for additional Seal Bond products that may support future program expansion The customer expressed satisfaction with both the process and the final product, noting Seal Bond’s responsiveness, cross-team collaboration, and commitment to meeting the project’s technical requirements and timeline.    Ready to strengthen your building envelope system lineup?
