Explore our advanced range of polyurethane and neutral silicone formulations designed for critical structural and perimeter sealing.
As architectural designs in the United States push the boundaries of structural dynamics, the need for high-movement joint sealants has reached an all-time high. Low modulus silicone sealants have emerged as the industry standard for sealing expansion joints in commercial high-rises, highway bridges, and residential envelopes. By providing exceptional movement capability (typically +100%/-50%) with minimal stress on the bonding substrates, these sealants ensure long-term weatherproofing and structural integrity across diverse American climates.
The United States commercial construction sector is undergoing a significant transformation, driven by modernization, energy efficiency codes, and resilient infrastructure initiatives. From the dense metropolitan landscapes of New York and Chicago to the rapid urban expansions in Texas and Florida, building envelopes are being subjected to extreme thermal cycles, heavy wind loads, and seismic activities. This has created a robust demand for high-performance low modulus silicone sealants.
Unlike high modulus sealants, which are rigid and best suited for structural glazing where high tensile strength is required, low modulus formulations are designed to stretch and compress with minimal effort. This property is crucial for joint sealing in materials with high thermal expansion coefficients, such as aluminum curtain walls, concrete panels, EIFS (External Insulation and Finish Systems), and natural stone claddings. As US architectural trends favor large-format glazing and mixed-material facades, local contractors and engineering firms heavily prioritize sealants that prevent adhesive or cohesive failures under continuous dynamic stress.
Several key trends are defining the manufacturing and distribution of silicone sealants in the United States today:
The geographical diversity of the United States demands customized applications of low modulus silicone sealants:
In earthquake-prone regions along the West Coast, structural joints must accommodate sudden, violent movements. Low modulus sealants with ASTM C920 Class 100/50 ratings allow joints to expand and contract dramatically without tearing, maintaining the building's weather barrier during minor seismic events.
Metropolitan skyscrapers in the Northeast face intense wind loads and thermal expansion. Low modulus neutral silicone sealants are applied to perimeter joints of glass and aluminum facade panels, absorbing the structural sway and temperature-induced movements of the building frame.
Coastal structures in the Southeast require sealants that resist continuous salt spray, high humidity, and intense solar radiation. Low modulus silicones provide an airtight, waterproof seal that does not degrade, crack, or chalk under severe subtropical UV exposure.
To be specified in US architectural blueprints, silicone sealants must meet rigorous performance standards. The primary benchmark is ASTM C920 (Standard Specification for Elastomeric Joint Sealants). This standard classifies sealants by type, grade, class, and use:
Low modulus sealants typically fall under Class 50 or Class 100/50, meaning they can handle joint movement of 50% to 100% expansion and 50% contraction. Additionally, they must comply with federal specifications such as TT-S-001543A and TT-S-00230C. Manufacturers supplying the US market must ensure their testing is verified by accredited third-party laboratories to guarantee that the physical properties—such as shore A hardness, tensile strength, and adhesion-in-peel—align with project specifications.
