New Silicone Sealants SV860 and SV861: Revolutionizing Joint Sealing for Infrastructure Projects
In response to the growing demands of modern infrastructure, two cutting-edge silicone sealants—SV860 and SV861—have been introduced, offering superior, long-lasting solutions for joint sealing in critical applications. Specifically designed for use in high-traffic environments like airport runways, highways, tunnels, bridges, and other concrete and asphalt pavements, these products promise unmatched weather resistance, flexibility, and durability, ensuring optimal performance under extreme conditions.
SV860: Self-Leveling Silicone Sealant for Harsh Environments
SV860 is a single-component, self-leveling silicone sealant that provides long-term weather-resistant sealing for expansion joints, contraction joints, and longitudinal joints. It is specifically engineered to meet the challenges of sealing joints in environments exposed to extreme temperatures, UV radiation, and other harsh climatic conditions typical of airport runways, highways, tunnels, and bridges.
Key highlights of SV860 include:
Low Modulus & High Displacement: Its formulation ensures excellent flexibility and the ability to accommodate joint movements, allowing it to maintain a strong bond even with significant concrete displacement.
Exceptional Weather Resistance: Accelerated aging tests confirm its resistance to high and low temperatures, UV exposure, moisture, and other environmental stresses. SV860 is built to endure the challenges of critical infrastructure with minimal maintenance.
Self-Leveling Formula: The sealant naturally flows into gaps and joints, ensuring a seamless, uniform finish that is easy to apply and guarantees reliable, durable protection.
SV860 is ideal for use in the most demanding infrastructure projects, providing a reliable seal that helps extend the lifespan of high-traffic concrete pavements exposed to severe environmental conditions.
SV861: Non-Sagging Silicone Sealant for Precision Sealing
SV861 is a one-component, non-sagging silicone sealant, specially designed for the same types of high-performance sealing applications but with a focus on vertical and horizontal joints where precise application is required. This sealant also excels in weather-resistant sealing for expansion joints, contraction joints, and longitudinal joints in airport runways, highways, tunnels, bridges, and other concrete pavements.
Key features of SV861 include:
Non-Sagging Formula: SV861 provides a high degree of stability, ensuring it stays in place during application without sagging, making it particularly suitable for vertical and inclined joints in infrastructure projects.
Low Modulus & Stretch Recovery: Like SV860, SV861 offers a low modulus to accommodate concrete movement. Its good stretch recovery properties ensure that it returns to its original form after joint displacement, providing long-term protection against cracks or leaks.
Proven Weather Resistance: Artificial accelerated weather aging tests confirm that SV861 offers excellent resistance to both high and low temperatures and prolonged exposure to UV rays. This makes it the perfect choice for sealing joints in concrete pavements exposed to extreme conditions.
SV861’s superior stretch recovery and non-sagging properties make it an ideal choice for more challenging sealing applications where precise control over material placement is crucial.
Meeting the Challenges of Modern Infrastructure
Both SV860 and SV861 are engineered to address the specific challenges faced in sealing joints in high-traffic infrastructure such as airport runways, bridges, highways, and tunnels. The self-leveling and non-sagging properties of the two products ensure seamless and precise installation in both horizontal and vertical joints, providing long-lasting protection against the stresses of joint displacement and environmental exposure.
Whether it’s sealing expansion joints in an airport runway or protecting concrete pavements from the harsh effects of extreme weather, these silicone sealants deliver superior durability, long-term performance, and cost-efficiency.
Future-Proofing Critical Infrastructure
As infrastructure projects become more complex and require more advanced materials, SV860 and SV861 provide an essential tool for construction professionals aiming to ensure that their projects stand up to the test of time. With unmatched flexibility, weather resistance, and ease of application, these innovative sealants offer an ideal solution for keeping joints in key infrastructure sealed and protected against environmental damage for years to come.
