Product Description

Product Description

Compatibility

In some cases, BESIL 8230 may fail to cure to optimum properties when in contact with certain plastics or

rubbers. Cleaning the substrate with solvent or baking slightly above the cure temperature will normally

eliminate the problem. Certain chemicals, curing agents and plasticisers can inhibit cure. These include:

- Organotin compounds - Silicone rubber containing organotin catalysts

- Sulphur, polysulphides, polysulphones and other sulphur containing materials

- Amines, urethanes, amides and azides.
