• Condensation-curing
• Flowable
• Two-component
• Good flow
• Low Shore A hardness (approx. 25)
• Great extensibility and elasticity
• High resistance to casting resins, particularly polyesters

Pourable, condensation-curing, two-component silicone rubber that vulcanizes at room temperature.

Due to its good mechanical properties of the cured material as well as its high resistance to polyester resins, ELASTOSIL M 4503 is particularly suitable as a mold-making material for reproducing models with very pronounced undercuts in polyester resins.

Other materials, such as plaster or wax, may also be cast without any problems from molds made of ELASTOSIL M 4503.

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.
