The Milliput Super Fine White Epoxy Putty is a very versatile model filler and adhesive. Milliputs drying time depends on the temperate, but at room temp it is hard in 3 to 4 hours. If youe speed the process by applying heat the hardening time can be reduced to just a few minutes. After Milliput is set hard, it will continue to cure and is fully dry in around 8 hours. After this it can be machined, drilled, tapped, turned, filed, sawn, sandpapered and painted. Milliput can be sandpapered and painted immediately after it has set. (it is advisable to wear eye protection during this process). Milliput is an excellent adhesive and will bond any of the following to itself or to any of the others - wood, brick, cement, metals, concrete, plastics, glass etc, but note that Milliput is not intended as a thin layer adhesive and should not be used where a paste, mucilage or thin glue is indicated. Milliput will set under water and is heat resistant up to 130C.
