Application


SiSiB® STP94000 is a high-modulus base resin engineered for high-performance moisture-curing sealants and adhesives. It is compatible with both hot and cold processes. It offers extensive formulation flexibility, broad bonding capabilities, high hardness and strength, extended shelf life, and a short tack-free time. It also exhibits a balanced combination of durability, reactivity, and storage stability, resulting from its unique chemical structure combining a polyether backbone with methyldimethoxysilyl functional groups.


SiSiB® STP94000 is suitable for a wide range of applications, including industrial and transportation adhesives and sealants, construction and product assembly adhesives, as well as general-purpose (DIY) and specialty uses.


  • Construction: Facade joints, window and door sealing, curtain wall panels, roof expansion joints


  • Automotive: Body seams, glass installation, interior trim bonding


  • Electronics: Joint sealing, moisture protection, thermal adhesive bonding


  • DIY & Consumer: Kitchen & bathroom sealing, flooring joints, tile grouting


  • Marine: Long-lasting, weather-resistant sealing for marine structures, boats, and ships

Packing and Storage


SiSiB® STP94000 is available in 200Kg steel drum and 1000Kg IBC tote.


SiSiB® STP94000 has a shelf life of 12 months from the date of manufacture when stored in its original, unopened containers below 30°C. After opening, containers should be tightly sealed to prevent contamination and moisture from entering the product.
