Addition Cured - Silicones
Pinkysil
New RTV silicone that is approved 'Skin safe'.
Fast setting, with 6 min worktime, and 15 minutes for demolding, can be used for body casting, as well as copying any small detailed item. Picks up finest detail from fingerprints to sculpture marks. Soft, 18A hardness, suitable for delicate parts as it is able to flex away from the cast surface.
Size: 500gm, 1kg, 2kg, 10kg

CloneFx
CloneFX is an addition curing RTV-2 silicone rubber primarily developed for life casting applications. This is a firmer silicone than Pinkysil, and when used for bodycasting, users should apply a generous vaseline coating over delicate parts of the body, particularly eyebrows and eyelashes, to aid in demolding the CloneFX when cured.
It is safe to use directly on the skin. CloneFX has an easy to use mix ratio of 1:1 and is coloured to ensure thorough mixing of the components. CloneFX will provide a mold that can reproduce the item many times over, unlike alginates that can only be used once.
TYPICAL PRODUCT USES

Banana-Skin
Banana-Skin is a two-component silicone elastomer that cures at room temperature by a polyaddition reaction that may be accelerated by heating. It is designed as a 13 Shore A high tear strength rubber providing excellent physical properties for glove & skin moulding applications. Banana-Skin is great for moulds with very large undercuts. Banana-Skin has high elongation and a coloured catalyst for easy mixing. Moulded parts can be produced without seams. Banana-Skin offers an extremely low mixed viscosity.
Ideal for -
- Skin Moulds
- Glove Moulding
- Moulds requiring a very soft silicone
- Moulding parts with large undercuts.

Silpression
SILPRESSION is a two-component, addition curing, kneadable impression putty designed for taking dental impressions. It is ideally suited to the manufacture of body moulds for the life casting industry. It is also the product of choice for fast impression moulds where time factors are an issue. 
- Dental Impressions
- Life Casting
- Any Fast Turnover Moulding
- Texture Stamps

Wacker M4642
General purpose grade. Moderately hard, high extensibility & excellent mechanical strength. This is a much more runny silicone in its liquid state compared with other Wacker silicones. Can be mixed and processed much more easily. M4642 has a moderately firm hardness showing good definition particularly with high level of detail in the cast pieces.
Size: 550gm, 1.1kg, 5.5kg
| Consistency | Pourable Dark Red |
| Mix Ratio | 100/10 |
| Viscosity (mPa s) | 15 000 |
| Hardness (Shore A) | 37 |

Wacker M4644
High resistance to polyurethanes & epoxy resin. Moderately hard, high mechanical strength. Preferred prototyping silicone. Once degassed to ensure clarity, items can be embedded and can be seen. Ensures casting material can be visible when pouring, to eliminate entrapped airpockets.

Wacker M4670
High resistance to polyurethanes & epoxy resin. Hard, high mechanical strength. Suitable for Low melt alloys. This is a very firm silicone giving high level of detail, however as it has a low degree of flexibility a matrix or multipart mold may be required to enable demolding safely and effectively.
