Chrome Cobalt Casting

SHERACAST

SHERACAST

This chrome investment is extremely reliable, easy to handle and cost effective. Suitable for gel or silicone duplication. Due to it’s very smooth surfaces no pre-coat is required.

SHERACAST can also be used with the shock heat process (with silicone duplication).

SHERAPOR-L

SHERAPOR-L

Solvent based dipping hardener Solvent free dipping hardener Special dip designed to seal and harden investment models and allows wax patterns to adhere better to the surface. Due to it’s low viscosity SHERAPOR-L easily soaks in to the models surface.

SHERAMUFFELFORMER

SHERAMUFFELFORMER MG

Mould former for the chrome technique. These thick elastic mould formers allow the investment to expand freely. The inside walls are rough in order that moulds may degas easily and hence prevent cracking. Ideally suited when using rapid burn out.

SHERADAN

SHERADAN

Polishing Electrolyte
SHERADAN achieves brilliant shiny surfaces even after a short treatment, ideally used at between 40-60 °C.

The already long life span of this electrolyte can be increased further by the use of DECALON.

5 litres - 709051

 

TITANIUM HOOK

Durable for many years, titanium hooks are not corroded by the electrolytic bath. This means that the bath does not silt up with impurities and can be used for longer. Time consuming cleaning of the electrodes is no longer necessary.

SHERABLOCK

SHERABLOCK

Block-out material.
SHERABLOCK is a reusable putty which can be used to block out undercuts, trays and impressions. It can also be used to fill in approximate spaces and as a spacer itself.

SHERAPOL 704

SHERAPOL 704

Pink, pre’ & high lustre polishing block.
For all metals, however we have found SHERAPOL 704 to be especially suitable for chrome cobalt alloys and non-precious metal alloys. SHERAPOL 704 has a pleasant smell, saves time and is very economical.

SOLDERING MATERIALS

SHERALÖTEINBETTMASSE LM 86

SHERALÖTEINBETTMASSE LM 86

Phosphate bonded soldering investment.
For giving a true fit to jobs cast in high fusing alloys after soldering. Stone free, therefore it causes no damage from sulphur nor the formation of an oxide layer on the alloy. Extremely heat resistant.

1kg tub - 203010
5kg tub - 203011

 

HEAT SHIELDING & INSULATING PASTE

HEAT SHIELDING & INSULATING PASTE

Asbestos free - protects all acrylics, ceramics and metals against damage caused by heat whilst soldering. The material can be easily applied to the areas requiring protection directly from the tube. The paste does not generate any fumes while soldering and is odourless. After soldering the paste can be rinsed off with water without any residue.

CHROME COBALT CASTING WAXES

All the wax patterns have been formulated by Berg Dental, who has many years experience founded in 1924.

These wax patterns are fabricated from high strength, have low memory to ensure they remain stable during application without distortion. The range of waxes formulated for Chrome Cobalt Casting techniques include the following:

Clasp Profiles

Anatomical clasps preshaped which burn without residue. These clasp profiles are manufactured in “lime green” and are available in the following:

Molar clasps
Pre-Molar Clasps
Straight Ring Clasps
Curved Ring Clasps

PLASTIFORM, Preformed Plastic Patterns

PLASTIFORM, Preformed Plastic Patterns

Thanks to the composition, manufacturing process and high quality of the materials used, PLASTIFORM are the ideal plastic patterns for use in the construction of partial denture frameworks. The excellent resistance to deformation and good adherence to the model will be appreciated by all technicians. The PLASTIFORM can stick quickly to the model without the need to use adhesive; just heat the model up to 38-40°C. No residue of plastic will be found inside the ring after complete heating in the burn out furnace.
