🔍 Product Description

VPE01/02 High Permeability Modified Epoxy Grouting Materials for Waterproof Plugging and Reinforcement Repair of Concrete Leakage.

This material is a type of grouting agent that takes modified epoxy resin as the main component. Formulated with reactive diluents, accelerators, and curing agents, it provides reinforcement, strengthening, water plugging, and anti-corrosion functions. It features low viscosity, excellent permeability, and strong bonding abilities.

⭐ Key Characteristics

Low viscosity and good permeability for fine crack injection.

Solvent-free system, safe and environmentally friendly.

Cures in water with excellent bonding effect, suitable for seepage areas.

High toughness to resist thermal expansion and contraction of concrete.

High mechanical strength for both water blocking and structural reinforcement.

❓ Frequently Asked Questions

Q1: Can this material be used in wet or underwater environments?

A1: Yes, the slurry cures in water with excellent bonding effects and can be directly grouted for construction on slight open water or seepage areas.

Q2: What is the primary advantage of the VPE01/02 modified epoxy?

A2: It offers extremely high permeability (low viscosity < 100 mPa.s) allowing it to penetrate very fine cracks, combined with high mechanical strength for structural reinforcement.

Q3: How should I store the material?

A3: The product should be stored in a ventilated, dry, and cool place, away from any fire or heat sources. The shelf life is 6 months under proper conditions.

Q4: Can I add thinners or diluents to the mixture?

A4: No, it is strictly forbidden to add any diluent. The product is designed as a solvent-free system to maintain its mechanical properties and safety standards.

Q5: What safety precautions should be taken?

A5: Construction should be carried out in well-ventilated conditions. Personnel must use safety protection equipment. Always test the gel time on-site before formal construction to avoid equipment damage from fast reactions.

Q6: What is the typical curing time?

A6: At 20ºC, the initial setting time is over 1 hour, and the final setting time is typically under 5 hours.
