Product description

Shore A 2/4 podiatric silicone in polycondensation paste form, specifically designed for the manufacture of very soft and elastic orthoses, with regenerative and antibacterial properties.

It is also ideal for reducing pressure points and calluses, and for making toe-specific items such as toe separators and pads.

Thanks to its innovative formula containing biotechnological components, it prevents maceration and bacterial proliferation, making it suitable for the warm, humid environment inside footwear.

It can be mixed with silicones from the same range of varying hardnesses to achieve specific Shore hardnesses and can be cured with any liquid or gel catalyst.

The working and setting times are very fast, ensuring precise and effective work.

It is easy for professional practitioners to handle and finish using cutting tools (scalpel blades) and rotary tools (drills).

How to use

How to use polycondensation podiatric silicone paste?

Catalyst dosage, mixture preparation and curing times for the manufacture of polycondensation silicone orthoses.

Steps

Measuring out the silicone and catalyst: Weigh the required amount of silicone using precision scales and add the gel catalyst in a ratio of 100:2.5 by weight, i.e. 0.25 g of catalyst for every 10 g of silicone. Do not exceed the specified amount: an excess of catalyst can reduce the orthosis’s lifespan.
Knead until a uniform colour is achieved: Knead the silicone vigorously with the catalyst until a completely uniform colour is obtained. Do not continue kneading once the silicone has started to harden, to avoid lumps that reduce the durability of the orthosis.
Applying and shaping the orthosis: As soon as the mixture begins to set, apply it immediately to the affected area and shape the orthosis, holding it in place for a few minutes. Any excess silicone can be set aside as a sample to monitor the setting process, which takes approximately 5 minutes.
Removal and finishing: Once set, remove the orthosis and trim it if necessary using blades or burs.
Wait for complete curing.: Full curing takes place after 24 hours. Only then can the patient begin to wear the orthosis.

Hints

Proper care: once the orthosis has been made, wait 24 hours before having the patient wear it. The orthosis can be washed with water and mild soap, dried by dabbing with a cloth or left to air dry. Dust generously with talcum powder.

Frequently asked questions

How much gel catalyst is required, based on the quantity of silicone?

The ratio is 100:2.5 by weight, i.e. 0.25 g of gel catalyst for every 10 g of silicone. Some examples: 10 g of silicone with 0.25 g of catalyst, 20 g with 0.5 g, 30 g with 0.75 g, 40 g with 1 g, 50 g with 1.25 g, 60 g with 1.5 g, 80 g with 2 g and 100 g with 2.5 g. We recommend weighing the silicone and catalyst using precision scales and not exceeding the specified amount: an excess of catalyst can reduce the lifespan of the orthosis.

What are the consequences of using an excess catalyst?

Using too much catalyst accelerates the catalytic reaction excessively, may cause clumping and reduces the lifespan of the orthosis. We recommend using only the specified dose.

How long do you have to mould the orthosis?

The working and setting time is approximately 5 minutes. The silicone should be applied and shaped as soon as the mixture begins to harden.

How long after treatment can the patient start wearing the orthosis?

After 24 hours, once the vulcanisation process is complete.

Can Extra Soft silicone be mixed with silicones of different hardnesses?

Yes, it can be mixed with paste silicones from the same range but with different hardness levels to achieve an intermediate Shore hardness.

Can it be mixed with A+B two-component silicones?

No. Catalyst-cured polycondensation silicones cannot be mixed with two-component polyaddition silicones.

For which orthoses is Shore A 2/4 silicone recommended?

For very soft and flexible palliative orthoses, such as toe separators and toe pads, and to reduce pressure points.

How do you clean a silicone orthosis?

Wash it with water and mild soap, pat it dry with a cloth or leave it to air-dry, and then sprinkle it generously with talcum powder.
