Solvent-based, electrically conductive, addition curing silicone rubber dispersion for fabric coating (topcoat)
- electrically conductive
ELASTOSIL® RD 6680 F can be used as an electrically conductive textile coating, e.g. in the manufacturing of conveyor belts and compensators or as antistatic topcoat.
ELASTOSIL® RD 6680 F is processed by thorough incorporation of a crosslinker.
Recommended ratio is 100 parts of ELASTOSIL® RD 6680 F plus

Adhesion of ELASTOSIL® RD 6680 F depends on substrate and can be varied by crosslinker type/amount and additives (e.g. CATALYST C05 or adhesion promoters). Preliminary testing should be carried out to determine optimum formulation and cure conditions.
This product is available in 25 kg pails.
Once opened, containers should always be resealed after use to prevent the platinum catalyst from being poisoned by amines, sulphur or phosphorus compounds.
The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
During storage fillers can settle. It is advisable to homogenize the product thoroughly before use.
