Rubber+ is a liquid silicone rubber for casting, capable of reproducing every single detail of the object on which it is poured. Excellent for reproducing even very small objects, with very small details and hidden corners.

BRAND NEW 100% MADE ITALY FORMULA WITH GREATER SHINE, RESISTANCE AND NON-STICK. SEEING IS BELIEVING!

N.B. All colors of silicone rubber can tend towards pastel shades.

To independently color the silicone rubber you can use our Stilcolor line of concentrated pastes that you can find at this link SILICONE COLORANTS.

Are you new to mold making? It might help you to read our short article on how to make silicone rubber molds.

To add even more fluidity, shine and softness to the silicone rubber for casting, you can add 2-10% (depending on the desired result) of SPECIAL OIL.

METHOD OF USE:

To use silicone rubber, proceed by adding 2% or 5% (by weight) [depending on the type] of catalyst (or part B) to the desired and previously weighed quantity of rubber. The quantity of catalyst must be calculated using a precision balance or alternatively using a graduated syringe considering that 1cc = 1gr (approximately). Then combine the components and mix everything carefully and slowly with the aid of a spatula, taking care to scrape the walls and the bottom well to obtain a homogeneous mixture throughout the mass.

In order not to risk having subsequent problems of bad mixing of the two components, we recommend working manually at most 600/700 grams of rubber.

The potlife (working time) is quite long and allows you to work very calmly before the start of the catalysis reaction. The silicone rubber is poured inside a container and on top of the object or artifact to be replicated, covering it entirely and taking care to let the rubber penetrate all the details (with the help, for example, of the tip of a toothpick) and without creating air bubbles.

Rubber+ silicone rubber generally does not require the use of release agents as it appears to be perfectly non-stick on most surfaces (except on silanised surfaces such as crystals, some glasses, natural stones, metals and on the silicone rubber itself). However, it is always recommended to apply a layer of release agent (you can find a type here) to facilitate the demoulding of the mold during replicas of very complex objects, with pronounced edges and undercuts and for any porous or scratched surfaces.

We remind you that the curing time ranges from 12 to 24 hours (approximately) and that both ambient temperature levels and the mixing method can affect the curing time.

TYPES OF RUBBER+ RUBBER:

RUBBER+ 10 SHORE A

Among those proposed, this type of rubber has the greatest softness and is recommended for the creation of more flexible casts and molds and for the replication of objects with many corners, undercuts and hidden points. The strength of this rubber is the high flexibility and resistance to torsion which favor the demoulding of highly complex objects.

CHARACTERISTICS:

Non-stick and does not require washing of equipment after use. For some particular surfaces, the use of a release agent may be recommended CLICK HERE
High resistance to twisting.
High flexibility.
Perfect reproduction of all details (even very small and hidden ones)
Excellent mechanical characteristics.
Low hardness (10 Shore A)

TECHNICAL SPECIFICATIONS: consult the relative technical data sheet which can be downloaded in pdf format from the download section.

RUBBER+ 20 SHORE A

With medium rubber hardness, it has the right compromise between resistance and flexibility which makes it the most versatile type for the creation of professional molds and casts of objects and manufactured articles of different materials.

CHARACTERISTICS:

Non-stick and does not require washing of equipment after use. For some particular surfaces, the use of a release agent may be recommended CLICK HERE
High resistance to twisting.
Perfect reproduction of all details (even very small and hidden ones)
Excellent mechanical characteristics.
Medium hardness (20 Shore A)

TECHNICAL SPECIFICATIONS: consult the relative technical data sheet which can be downloaded in pdf format from the download section.

RUBBER+ 40 SHORE A

The liquid silicone rubber for casting at 40 Shore A is more rigid and with greater resistance to chemical agents than the softer types of rubber and is recommended for the production of molds for objects or artefacts with fewer hidden details and which mainly have flat surface or for bivalve moulds. This is because, once fully matured, the greater hardness and stiffness of the rubber does not allow for considerable flexibility and torsion of the mould.

CHARACTERISTICS:

Non-stick (on plastic surfaces) and for some surfaces it is necessary to apply release agents (for example particular steels) CLICK HERE
Good resistance to twisting.
Good reproduction of all details
Low flexibility
Excellent mechanical characteristics.
Medium-High hardness (40 Shore A)
