A one part, high modulus, modified polymer sealant which cures, on exposure to moisture vapour, to form a tough, elastic rubber.

Suitable for internal applications in hospitals, food processing areas, clean rooms, etc. where resistance to MRSA bacteria is necessary.

Can be overpainted with a suitable protective coating if required. Note that, due to the wide variety of paint and coating systems available, a pre-test is required to assess compatibility with the paint system.
