Working in conjunction with our sister company American Colloid Company (ACC), Volclay International Pty. Ltd. stocks an extensive range of smectite clays which include Magnabrite, Hectabrite & HPM. These selectively mined and processed versatile minerals are commonly used in cosmetics, pharmaceuticals, ceramics, paints, coatings and other industrial specialty applications.
Agricultural: Agro-Lig Granular is a naturally occurring organic substance consisting primarily of humic acids. The humic acids contained in Agro-Lig form a unique complex of nutrients which are readily absorbed by plant roots. The high carbon content stimulates beneficial soil organisms, while continued use improves the structure and organic content of the soil.
Detergent & Fabric Softeners: working in conjunction with AMCOL Minerals Europe and our AMCOL Thailand plant, we stock and distribute a range of agglomerated and granulated bentonites. Customers such as Unilever & Colgate currently utilise the benefits of products such as Green Clay Aloe Vera or QPC 200G.
Paper Manufacturing Technologies: For more than 20 years, AMCOL Paper Technologies has provided bentonite products for papermakers worldwide used in a variety of applications — retention, drainage and formation, pitch control, freshwater conditioning, and wastewater treatment. AMCOL Paper Technologies has dedicated research facilities in the United States and England with additional product and material testing capabilities in Thailand and China. Utilizing product and minerals development groups and industry leading technology, AMCOL Paper Technologies products enhance paper processing, quality and manufacturing.
In the wine processing industry, cloudiness that creates an adverse consumer reaction must be removed. Cloudiness and its removal has been an important issue in this industry for centuries. Wine grade VOLCLAY BENTONITE, a low cost mineral colloid can be effectively used as a solution to this problem.
Although primary filtration takes care of large particles, macromolecular solids, which create colloidal suspension, pass readily through filter cloths and remain in the final product.
In the case of wine clarification, undesirable suspended (positively charged) proteins will cause cloudiness. They are true colloids and obey colloidal laws, therefore one excellent approach is to attack them with equally strong colloids of a different type.
VOLCLAY WG POWDER or GRANULAR bentonite is a true colloid, negatively charged which, when completely dispersed in water is added to the cloudy wine. Dispersed particles of Volclay have a uniform negative surface charge, thus attract and hold the positively charged protein colloids in suspension. The two colloids neutralise each other and form a precipitate, which settles to be filtered without difficulty.
VOLCLAY Wine Grade bentonite is available at low cost through specialist distributors nation wide.
