It may be easily used to manufacture anti-adherent molds intended for molding objects in chocolate, sugar, marzipan and for producing decorative sugar pieces of bakery, biscuits and confectionery products.
Mixing of the two components: SILBIONE RTV 4428 A 100 parts + SILBIONE RTV 4428 B 10 parts
SILBIONE RTV 4428 A (ex 71557) properties:
Apearence: viscous liquid
Hardness: 28 shore A (middle-high)
Elongation to break (%, approx.): 600% (high)
Tear strength (KN/m, approx.): 15 kN/m (high)
Thermal conductivity: W/m.K 0.23
Temperature range in continuous use: 180°C
Minimum peak temperature in use: - 70°C
Linear shrinkage (% after curing at 23°C): 0,05%
Note: hot polymerization doesn't compromise SILBIONE RTV 4428 A+B (ex 71557) properties; anyway we remark that it causes a greater linear retraction.
Pot life (at 23°C, minutes, approx): 90 minuti
Demoulding time (at 23°C, minutes, approx.): 16 h
Viscosity (at 23°C, mPa.s, approx.): 25.000
SILBIONE RTV 4428 B (ex 71557) properties:
Apearence: low viscous liquid
SILBIONE RTV 4428 A+B is a two component silicone elastomer which cures at room temperature by an addition cure reaction, food contact grade, it may be easily used to manufacture anti-adherent molds intended for molding objects in chocolate, sugar, marzipan and for producing decorative sugar pieces of bakery, biscuits and confectionery products.
- non-stick molds for casting in the manufacture of chocolates, candies, pastries, biscuits and sweets
- molds for the pressing of almond paste and pasta for cakes
- vertical molds (a brush or spatula).
- excellent mechanical resistance
