Milliput Standard/Yellow-Grey is an extremely versatile two part epoxy putty. Its uses range from modelling to plumbing, car bodies, caravan and boat repairs to many other applications in home and industry. The two sticks have a long shelf life but once mixed, the resultant putty is at first soft and highly adhesive and then gradually hardens. Speed of hardening is dependent on temperature and at normal temperatures (20-25°C) Milliput becomes rock hard in three to four hours. By the application of heat the setting time can be reduced to a few minutes. After setting hard, Milliput continues to cure and is fully cured after an elapse of time equal to the setting time at.
