silicon elastomer mastic, black, MS 107, BOSTIK

MS Polymer based bonding compound.
Odourless, solvent and isocyanate free, these sealants crosslink about 1.5 times faster than silicon in contact with atmospheric moisture to form a flexible joint.
Specially intended for bonding or sealing materials between themselves or on other supports such as aluminium, stainless or galvanized steel, zinc, copper, brass, metal, glass, PVC, polyester, and wood, …except for untreated polyethylene, polypropylene and Teflon; does not corrode metals. Excellent adhesion without primer, including on moist supports (non-saturated and non-dripping). Very good resistance to weathering and UV radiation. Compatible with most paints and can be painted after full cure.
The resistance values are provided as a guide. A preliminary test is always recommended.

MS107, regains its original properties after compression or elongation. Superior resistance (about 60 kg/cm²) and medium viscosity are an ideal compromise for groove bonding. Black.
