Description
Bostik OB1 Diamond Crystal Clear Universal Sealant and Adhesive is the clear-finish version of the proven OB1 formula designed for applications where appearance matters and a visible bead or joint needs to disappear into the finished surface. Solvent-free, odorless, and crystal clear from application through full cure, it bonds and seals a wide range of common building materials indoors and outdoors, even when the surface is wet. The high UV resistance formula holds its clarity over time without yellowing, and the flexible cured bond accommodates joint movement without cracking or pulling away. Paintable with water-based paints for complete finish integration. Shelf life of 18 months when stored in the original sealed packaging between 41°F and 86°F in shaded conditions.
Features
Crystal clear formula maintains transparency from application through full cure and over the long term, making it ideal for glazing, glass, clear plastics, and any application where a visible bead is undesirable.
High UV resistance prevents yellowing and maintains clarity in applications with indirect sun exposure recommended for use away from prolonged direct UV exposure outdoors.
Solvent-free and odorless formula is safe for use in occupied indoor spaces without ventilation concerns during application.
Bonds and seals a wide range of common building materials for non-structural sealing applications where a minimum of joint movement is expected.
Works in wet or dry conditions can be applied to damp surfaces without loss of adhesion or seal performance.
Paintable with water-based paints once cured, allowing complete concealment of the bead in finished paint applications.
Suitable for indoor and outdoor use high UV resistance makes it appropriate for exterior applications away from direct, prolonged sunlight exposure.
Two-in-one sealant and adhesive function reduces the number of products needed for mixed bonding and sealing applications.
18-month shelf life when stored between 41°F and 86°F in shaded conditions in original sealed packaging.
