Needed anywhere that silicone is used
Digesil® NC dissolves cured silicone and can be used to remove silicone from components, floors, surfaces, tools, moulds process equipment in engineering, construction, glazing and electronic industries. The areas of potential usefulness are so wide it is impossible to list them all.
NB. Raising the temperature to 50 OC will dramatically speed up the process especially with high cross-linked or other difficult silicones.
Important: As little as 0.3% water stops the catalytic action so all surfaces and areas being treated must be dry. In addition the presence of water can cause Digesil® to become corrosive to metals. Most solvents and detergents and many other chemicals also deactivate the system so make sure everything is free from contamination. Do not store in an open container. Enough water can be absorbed from the atmosphere to stop the product working.
As the number of applications is so numerous it is only possible to give general guidelines as to how to use the product. Please contact us with details of your process if you would like more specific application details.
Best results will be achieved by immersion of the equipment to be cleaned in a tank of Digesil®NC. Slow movement of the liquid with a pump or impeller will increase the speed of action fourfold. It is important that the tank is fitted with a lid to keep out atmospheric moisture. Leave until all silicone is dissolved. The time required will depend on the thickness of the silicone and its degree of cross-linking but Digesil®NC will most likely loosen and debond cured silicone residues in 30 minutes to 1 hour. Repeated brush applications can be used if immersion is not possible. After treatment, rinse well with water or solvent to achieve a silicone-free surface. For best results, brush or swab with iso-propanol and rinse in flowing water otherwise rinse in water with some brushing.
NB Do not replace parts wet with water or iso-propanol into Digesil. Both can stop Digesil® from working and water can make Digesil® corrosive to metals.
