ELASTOSIL® RD 6620 F
Solvent-based addition curing silicone rubber dispersion for textile coatings (topcoat)
Properties
- Matt topcoat
- Reduced coefficient of friction
- High abrasion stability
Data sheets
ELASTOSIL® RD 6620 F is a silicone rubber dispersion in xylene. Due to the high Shore hardness after vulcanization, a matt, non-blocking surface is obtained.
ELASTOSIL® RD 6620 F is therefore especially well suited for the application as topcoat on flexible silicone coatings.
ELASTOSIL® RD 6620 F is processed by thorough incorporation of a crosslinker.
Recommended ratio is 100 parts of ELASTOSIL® RD 6620 F plus
- 1 part of CROSSLINKER W
Pot life at 23°C: 3 days
Recommended curing conditions: evaporation of the solvent at 70 - 90°C and curing of the silicone rubber for 3 min at 150°C or 1 min at 180°C.
Adhesion of ELASTOSIL® RD 6620 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.
Packaging
This product is available in 25 kg pails and 180 kg drum kits
Storage
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.
