HSCA-4 Technical Specifications

❄️ Critical Tips for Freezing Weather:

To ensure HSCA-4 reaches peak 120MPa pressure in cold air, follow these rules:

• Use Warm Water: Mix with water between 20°C - 30°C to kickstart the chemical reaction.

• Insulation: Cover filled holes with plastic tarps or mats to retain internal reaction heat.

• Matched Tools: Use Topking Rock Drills and 38mm-40mm bits for standard borehole patterns.

Why Choose Expandag HSCA-4?

• Zero Project Delays: Continue mining and demolition work throughout the winter season.

• Safe & Predictable: Avoids the unpredictability of explosives in extreme cold.

• Global Supply: Trusted by contractors in Moscow, Toronto, and Stockholm.

Winter FAQ

Q: What happens if I use HSCA-4 in summer?

A: DANGER! Never use the winter version in temperatures above 10°C. HSCA-4 is extremely reactive and will cause an immediate, dangerous blowout in warm weather. Always match the version to the ambient temperature.

Q: Does it work on frozen concrete building foundations?

A: Yes. HSCA-4 is highly effective for breaking reinforced concrete even when the structure is at sub-zero temperatures, provided the mixing and insulation guidelines are followed.

Q: How do you ship to cold regions like Canada or Russia?

A: We use heavy-duty moisture-proof packaging to ensure the powder stays dry during long-distance transit to cold regions, ensuring the chemical integrity of the product upon arrival.
