BoPin 850 is a single-component, moisture-curing MS polymer adhesive engineered for high-strength panel bonding and heavy construction assembly applications. Available in two performance variants to suit different installation requirements: the standard grade delivers exceptional tensile strength of 3.3 MPa with good elongation for applications where flexibility is needed alongside strength; the instant-grab grade provides immediate anti-slip resistance on vertical surfaces with fast skin formation of 5 minutes — critical for large-format stone and sintered panel installations where temporary mechanical support would otherwise be required. Both variants cure at room temperature to form a strong, flexible rubber with good ageing resistance and long-term durability.
