Duralac is supplied ready for use and must not be thinned. It is best applied by brush. When Duralac is applied to metal or other surfaces the volatile solvent evaporates and the compound sets to the touch, but remains tacky for a considerable period. It is important that the joint should be closed while Duralac is still tacky to ensure that it will flow sufficiently under pressure to close the gaps in the joint. It will harden somewhat if a thin film is left exposed to the atmosphere for a long period and this will prevent the making of a close joint.
- Has low solubility in water and will not erode with time, even when subjected to high pressure from considerable water flow
- Has excellent adhesion properties to most substrates and because of its tough flexible composition, has very low water absorption
- Has a two year shelf life from the date of despatch when stored below 20°C. Once a container is opened, the remaining Duralac will form a skin
