Softer grade of silicone moulding rubber used for creating reusable moulds of original parts requiring deep undercuts

SKU: 370 Category:

Description

370 Silicone Moulding Rubber is a softer grade of moulding rubber used for making highly detailed reusable moulds of original items and parts to be copied via casting.

Due to its softness, flexibility and high tear strength, 370 Rubber is particularly good for taking moulds where there are deep undercuts.

Once the silicone has cured and the mould been formed, resin is poured into the mould to make multiple accurate copies of the master.

Scale model makers use 370 Silicone Moulding Rubber to produce moulds of models they have sculpted from epoxy putty or modified. They can then quickly and easily create numerous reproductions of the original model.

Resin artists used 370 Silicone Moulding Rubber to reproduce original pieces of jewellery, figurines and other artefacts. 370 can also be used by industrial users to copy machine parts, avoiding repetitive tasks when making prototypes or new components.

Moulds taken from Grade 370 have good dimensional stability and excellent tear strength. They are flexible, have high mechanical properties and are chemically resistant. This means they can be used with aggressive chemicals, such as high styrene polyester resins or epoxies

The quality of 370 Silicone means that moulds can be reused over 20 times, depending on the size and complexity of the part being copied.

370 Silicone Moulding Rubber comes with catalyst, a reusable pipette, mixing cup and stirrer. The 45-120 minute pot life means that there is plenty of time to pour the rubber and allow air bubbles to disperse.

We have detailed the whole mould making and casting process on the Showcase Section of our website, including a video showing how to make and use a two-part silicone mould for resin casting. The video is also available under the Videos tab on this product page.

For full technical details of 370 Silicone Rubber, please see the Data Sheets tab. The de-mould time of 370 Silicone is 10 hours.

370 Silicone Moulding Rubber Testimonials

Peter Hallett, resin casting of historical buildings expert:

“I use 370 Moulding Rubber in all my casting and the quality of the resulting mould is always extraordinary. I get around 20 complete buildings before the mould starts to break up which shows just how durable and long-lasting a mould made from 370 can be.”
