4. Application Instructions:

1. Preparation Method 1:
   Add DXCRSL2 into the specified amount of water and heat to 40-50°C. Then, add hydrochloric acid (HCl) to adjust the pH to 2-3.

2. Preparation Method 2:
   Another method involves adding 90% of the required acid to water at 45°C, followed by the addition of DXCRSL2 to the acid water. Add the remaining acid to achieve the desired pH.

For CRS-2 bitumen emulsion, the typical dosage of DXCRSL2 is 0.2-0.3%.

5. Application Scenarios:

DXCRSL2 is widely used in a variety of applications that require high-quality CRS-2 bitumen emulsion production:

• Slurry Seals: Used in slurry seal applications to create a durable surface on roads, improving their skid resistance and extending their lifespan.
