The perfect deflocculant* as it's very simple to use. A great alternative to Sodium Silicate/Soda Ash other branded agents.
*Deflocculant: Used mainly in casting slips but they can be used in some glaze and clay slurries. The addition of a deflocculant reduces the viscosity of a liquid.
When mixing your casting slip, take the weight of your dry clay or powder and times it by .0024. For example 5kg of powder will require 12g of the deflocculant.
However, when making larger quantities of slip, we first recommend mixing the clay with water to achieve the right specific gravity before adding the deflocculant. You should aim for a specific gravity of around 1.7 to 1.8, for information on how to measure this, see our product attachments. You may need more deflocculant for your mix but this ratio gives you a good starting point.
If your casting slip is already mixed with water, once again make sure it has the right specific gravity then add a drop of the dispex until it is flowing to your desired consistency. In this instance only add small amounts of deflocculant.
Dispex could be an irritant to some so wear, gloves and glasses at the very least.
Do not use in the domestic environment and eat or drink in your workspace.
In keeping with our overall general advice, we suggest wearing full PPE when handling raw materials. This includes a mask, safety
glasses, and gloves. We also suggest working in a well ventilated area.
It is a sensible precaution for children not to work with raw materials.
