HSCA-1 High-Temperature Stone Cracking Powder (25°C - 50°C)
HSCA-1 is a high-temperature soundless cracking agent specifically engineered for non-explosive rock breaking and concrete demolition in extreme climates. It functions as a cementitious expansive grout that generates controlled internal pressure to fracture hard materials without the need for traditional blasting permits.
In high-heat regions like the Middle East, India, and Sri Lanka, choosing Topking HSCA-1 ensures safety and efficiency where standard mortars might fail.
It is a premium high-temperature expansive mortar solution, comparable to leading international brands in performance and reliability, provided at competitive factory-direct pricing.
