Properties:
The main composition of dispersant KR-904 is anion polymer. It can adsorb on surface of microparticles resulting in static repulsion, resulting in disperse and preventing sedimentation and coarse turn-back. Dispersant KR-904 is little foaming, innocuous, non-corrosiveness and non-hazardous.
KR-904 is used as chelant in papermaking coating, building coating, concrete retarder, water reducer, woven and dyeing. Its performance can reach to that of SN-5040. Adding KR-904 to slurry during grinding process of bolus alba, lime carbonate, pottery clay, titanium pigment, French chalk, barium sulfate, coal-water slurry, etc., the viscosity can be largely reduced and the dispersed slurry is stable.

Protective measures for dispersant KR-904:
When handling KR-904, it is important to follow appropriate protective measures to ensure safety. Here are some general guidelines:
- Personal Protective Equipment (PPE): Wear appropriate PPE, including gloves, safety glasses or goggles, and protective clothing, such as a lab coat or coveralls.
- Ventilation: Ensure good ventilation in the working area to minimize exposure to vapors or dust. If working in an enclosed space, use local exhaust ventilation or wear respiratory protection if necessary.
- Handling: Avoid direct contact with the skin and eyes. In case of accidental contact, immediately flush the affected area with plenty of water for at least 15 minutes and seek medical attention if needed.
- Storage: Store KR-904 in a cool, dry, and well-ventilated area away from incompatible materials. Follow any specific storage requirements mentioned on the product’s safety data sheet (SDS).
- Spill and Leak Response: In case of spills or leaks, contain the material using absorbent materials (such as vermiculite or sand) and prevent it from entering drains or waterways. Clean up the spill following appropriate procedures and dispose of waste according to local regulations.
- Disposal: Dispose of KR-904 and its containers in accordance with local regulations. Do not pour it down the drain or discard it in the environment.
It is important to consult the specific safety data sheet (SDS) and guidance provided by the manufacturer or supplier of KR-904 for detailed and accurate information on handling and protective measures.
