HP-1 low viscosity high strength epoxy injection resin penetrates fine cracks effortlessly while providing robust structural support.
Ultra-low <30 mPa·s viscosity for superior flow into micro-cracks.
High ≥50 MPa compressive strength for long-lasting repairs.
Excellent wet/dry bond (≥2.0 MPa wet) resists water and chemicals.
Over 30 minutes operable time with easy 3:1 mixing ratio.
Product Introduction
HP-1 epoxy injection resin stands out for its low viscosity under 30 mPa·s paired with high compressive strength over 50 MPa, making it a top choice for concrete crack repairs where deep penetration and durability matter.
As a two-component system mixed at 3:1, it flows into narrow voids without effort, curing to a tough bond that enhances structural stability in environments like bridges or basements.
This resin excels in wet conditions, offering impermeability above 300% and resistance to shrinkage, ensuring reliable performance for professionals seeking efficient, high-strength solutions.
