ASMACO 2890 SL utilizes a neutral-cure formulation that is non-corrosive and highly resistant to ozone, UV radiation, and extreme temperatures, ranging from -30°C to 185°C. Upon exposure to atmospheric moisture, it cures into an ultra-low modulus, flexible silicone rubber that accommodates substantial joint movement. This ultra-low modulus is particularly crucial for asphaltic substrates, which typically have low tensile strength, helping to minimize strain and enhance durability. The sealant’s self-levelling nature allows for easy and efficient application, making it an ideal choice for horizontal joint sealing in roads, runways, and industrial pavements.
