Product Applications
SIHA Bentonite G Fining Agent
SIHA Bentonite G fining agent can be used alone either for stabilizing protein or in combination as a clarification aid prior to gelatin silica sol fining. Due to its high activity, lower quantities are usually required in comparison to conventional bentonites when SIHA Bentonite G fining agent is used.
The high clarification and adsorption effectiveness of bentonite is based on the swelling properties of the individual bentonite particles. This increases the size of the inner surface many times over. In order to achieve this effect, SIHA Bentonite G fining agent should be vigorously stirred into a volume of water 3 to 5 times the quantity of SIHA Bentonite G until the granulate is completely suspended. When stirred occasionally, SIHA Bentonite G fining agent will swell completely within a few hours (it is best to set the batch the day before fining). Supernatant water which may arise can be poured off.
Although it is generally possible to use bentonite without pre-soaking, the quantity required will increase since it has practically no time to swell.
