Model NO.: BK-300A
Trademark: Jingyi
Origin: Huzhou, Zhejiang
BK-300A is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systems of low to medium polarity.

1. Advantages: 
☆ High gelling efficiency over low to medium polarity organic liquids,
      especially in aromatic compounds.
☆ Ideal thixotropy property and anti-sediment property.
☆ High viscosity and excellent thickening property over a wide temperature range.
☆ Imparts particle suspension, preventing hard settling of pigment and fillers.
☆ Exerts strong film reinforce action in organic binder systems.
 
2. Typical Properties:

White Free Flowing Powder 1.7g/cm3 ≤3.5% ≥98% ≤35%
 
3. Typical Applications: 
Acrylic paint Road paint
Alkyd paint Inks(mineral oil)
Anti-corrosion paint  Inks(Nitro)
Baking paint Adhesive
Bituminous paint Putties and sealant
Chlorinated rubber paint Lubricating grease
Polyester paint Cosmetics
Primer paint Waster water treatment
Refractory  
                 
4. Incorportions:
BK-300A belongs to the conventional type of organoclay group, which requires mechanical energy, shear forces applied with a goods dispersion equipment, and a chemical (polar) activator to reach the proper level of delamination of the organoclay platelet stacks.

Polar Activator: Dosage of polar activator (such as 95%ethanol, 95%methanol, 95%acetone or propylene carbonate) is 40%-60% by weight of BK-300A.

It is always recommended to determine the proper level of addition by experiment. Either defect or excess of chemical activator would result in poorer viscosity development.
 
5. Recommended Levels:
The amount of BK-300A rheology modifier required depends upon the type of organic system and the degree of thickening or other properties desired. Addition levels are typically between 0.1%-3.0% based on the total formulation weight.

Sponge Sandpaper

Sunplus Sponge is made with aluminum oxide and latex paper with foam backing. Aluminium Oxide grains provide fast sanding results. The foam backing is suitable for hand sanding of corners, angles of car body parts. The foam allows pressure to be applied evenly and thus reduces the risk of sanding through the surface.

Sunplus Abrasives Co.,Ltd is a leading company in the field of researching and manufacturing premium quality coated abrasives for a wide range of applications.
Founded in 2004, Sunplus has developed into an enterprise with the leading fully - automated Germany system production line and technology to make high and stable quality sandpaper. All our materials are imported from Europe, Japan and Korea, which assures high quality products from the source.
We constantly invest in research and development so as to ensure that our products will always be a step ahead of competition.
