Sikaflex®-112 Crystal Clear | NASIR & SONS SIKA PAKISTAN

This crystal-clear adhesive and sealant is a one-component, moisture-curing solution developed for professional bonding and sealing applications in construction and finishing works. Formulated with silane-terminated polymer technology, it combines the properties of an adhesive and a sealant in a single product, providing strong adhesion, elasticity, and a clean transparent finish. The product delivers excellent initial grab, allowing fast and reliable fixing of components, while curing to a flexible, durable seal capable of accommodating movement. Its transparent appearance makes it ideal for applications where aesthetics are important, such as visible joints, decorative installations, and glass-adjacent bonding. It bonds effectively to a wide range of substrates including concrete, masonry, stone, ceramic, wood, metals, glass, and PVC, without the need for additional mixing. Suitable for both internal and external use, it performs reliably even in hot and tropical climatic conditions. The formulation is low-emission, environmentally compliant, and suitable for modern green-building requirements. Once cured, it provides long-term resistance to weathering, aging, and temperature variations, making it an ideal choice for general construction bonding, sealing around fixed components, and finishing works where clarity, flexibility, and durability are required.
