R METAL - Liquid silicone rubber resistant to high temperatures, ideal for metal moulds

In stock, ready to ship


R Metal is the high-temperature resistant rubber ideal for making molds for lead soldiers and other metals with a low melting point, and for making coatings suitable for protecting mechanical, electrical or electronic components.

✔️SILICONE RUBBER FOR HIGH TEMPERATURES: This rubber is specific for resisting high temperatures and, for this reason, it is ideal for making molds that require the casting of molten metal with a low melting point (such as molds for lead soldiers or tin) or for protective coatings on mechanical or electronic components.

✔️HARDNESS: Equipped with high hardness with Shore 55 and high viscosity, R Metal high temperature resistant rubber faithfully reproduces even the smallest details and allows you to create molds for toy soldiers, in which tin and molten lead can be poured directly.

✔️HOW TO USE: It is necessary to vigorously mix the white base A and the transparent catalyst B according to the proportion 100 : 5 (for example 100g Base A and 5g Catalyst B).

✔️NOTE: It has a very rapid catalysis compared to other products on the market and can have a linear shrinkage over time of 0.7%

R Metal is odorless bi-component rubber (base + catalyst), which has a high hardness (55 ShoreA) and a high viscosity. 

It allows you to copy faithfully even the smallest details, and to make molds of any type and size.

It is particularly suitable for making metal objects with a low melting point (eg tin, lead etc). 

Given the high viscosity, we recommend using the vacuum machine before pouring the product to eliminate air bubbles.



  • 100g  R Metal rubber
  • 5g (c-metal)catalyst

Perfect for tin, lead and low melting alloy objects

It hardens in 12 hours and is highly resistant to laceration. To be used in the presence of an adult.
