FAQs

What is this silicone rubber kit used for?

This two‑component silicone rubber system is engineered for precision mould‑making, tooling and casting. The kit delivers high tear strength, minimal shrinkage and strong dimensional stability, making it suitable for detailed reproduction of surfaces in prototyping, production tooling and clean‑manufacturing environments.

How do I mix and cure the material?

Mix the base and curing agent by weight in a ratio of 100 : 10. The mixed material has a working time of roughly 30–60 minutes at room temperature and reaches full cure in about 4‑7 hours at ~25 °C, depending on section thickness.

What are the mechanical and physical properties after cure?

Once cured, the rubber achieves Shore A hardness around 25‑26, elongation up to ~850‑900 %, tensile strength approximately 7 MPa and tear strength around 23 kN/m. Linear shrinkage is less than 0.1%, ensuring dimensional fidelity.

Is this material suitable for cleanroom or contamination‑sensitive environments?

Yes - the system’s low shrinkage, high dimensional stability and clean‑manufacture orientation make it well‑suited for cleanroom moulding, precision tooling and casting where contamination control and high accuracy are critical.

What are the storage and usage limitations I should be aware of?

Store unopened containers in a cool, dry place, ideally at or below 25 °C. Avoid prolonged use at continuous temperatures above about 200 °C, as long‑term exposure may degrade elasticity. Cure inhibition can occur if the mould contacts substances like amines or sulfur‑containing materials.
