M4503/T35 Condensation Silicone Rubber

***UPDATE TO M4503 – AS OF 03/07/2023 THIS FORMULA MAY BE USED WITH THIXOTROPIC C – READ TDS FOR DETAILS***

M4503 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 Flow
• Low Shore A Hardness (approx 25)
• High Tear Strength
• Great extensibility and elasticity
• Excellent long term stability of the mechanical properties of the cured rubber
• High resistance to casting resins, particularly polyester
• May be mixed exclusively with Thixotropic C in order to turn the flowable formula into a brushable formula

Recommended for: General Moulding, Large Parts, Plaster & Resin casts
Potlife & Demould: Work time – 90 mins / Demould time – 24 hrs
Hardness & Type: Shore A25 +/-2 Silicone Elastomer, 40000cps
