ELASTOSIL® M4503 & T51 (New Catalyst Formula) Wacker RTV-2 Silicone RubberM4503 is the star of our condensation silicone range due to the excellent mechanical properties of the cured rubber, as well as it’s high resistance to casting resin. M4503 is especially suitable for reproducing models with pronounced undercuts in casting resins. Other materials, such as wax and plaster, may be cast without any problems in moulds made from M4503.M4503 is a pourable, condensation-curing, two component silicone rubber that cures at room temperature and features:Good FlowLow Shore A Hardness (approx 25)High Tear StrengthGreat extensibility and elasticityExcellent long term stability of the mechanical properties of the cured rubberHigh resistance to casting resins, particularly polyesterMay be mixed exclusively with Thixotropic C in order to turn the flowable formula into a brushable formulaTechnical Features:Recommended for: General Moulding, Large Parts, Plaster & Resin casts Potlife & Demould: Work time – 30 mins / Demould time – 10-20 hrs Hardness & Type: Shore A25 /-3 Silicone Elastomer, 38,000cps
