Resin Capsule / Cartridge
What is Resin Capsule / Cartridge?
Resin anchoring agent is a high-performance chemical anchoring material used in geotechnical engineering and structural reinforcement. It is normally used together with anchor bolts or steel bars. Through the rapid reaction and curing of two-component resin, a high-strength bonding mass is formed inside the borehole to achieve a reliable connection between anchor bolts and rock mass or concrete. Featuring fast curing speed, high bonding strength, zero shrinkage and strong corrosion resistance, this product can significantly improve the overall stability of supporting structures. It is widely applied in mine roadways, tunnel projects, slope support, building structure reinforcement and other scenarios, serving as one of the important high-efficiency anchoring solutions in modern engineering.
Product Overview
Resin anchor agent is a high-performance chemical anchoring material based on a polymer resin system. It is typically used together with rock bolts, anchor rods, or reinforcing steel bars. Through chemical bonding and curing reactions, it forms an integrated load-bearing structure with the base material.
During curing, the product exhibits excellent flowability and filling performance, allowing it to fully fill the gaps between the borehole wall and the anchor rod. This results in a high-strength, non-shrink, and fully bonded anchoring effect.
Resin anchor agents are widely used in mining roadway support, tunnel engineering, slope reinforcement, underground construction, and structural strengthening projects. Compared with traditional cement-based anchoring materials, resin systems offer significant advantages in curing speed, bonding strength, and construction efficiency.
Core Advantages
1. High Bonding Strength
After curing, the resin forms a dense polymer structure with extremely strong bonding force between the anchor rod and surrounding rock or concrete, significantly improving load-bearing capacity in high-stress environments.
2. Fast Curing Speed
Depending on formulation, the product can be designed as fast, medium, or slow curing. Initial strength can be achieved within minutes, greatly improving construction efficiency and project progress.
3. Excellent Corrosion Resistance & Durability
The resin system has outstanding water resistance and chemical corrosion resistance, ensuring long-term stable performance in humid, acidic, alkaline, and underground environments.
4. Easy Installation & Strong Adaptability
No complex equipment is required. The anchor capsule can be inserted directly into the drilled hole. It performs well in dry, wet, and partially water-bearing conditions.
5. Non-Shrink Performance
The material shows minimal volumetric shrinkage during curing, ensuring continuous tight contact between the anchor rod and borehole wall for stable structural performance.

Structural Details
The resin anchor agent typically adopts a two-component system consisting of Resin (Component A) and Hardener (Component B). During installation, the two components are mixed through mechanical rotation or drilling action, triggering a chemical reaction.
1. Packaging Structure
High-strength film or capsule packaging ensures stability during transport and prevents premature reaction.
2. Two-Component Ratio Design
The precise ratio between resin and hardener ensures controlled curing time and consistent performance.
3. Curing Reaction Mechanism
Under mixing action, the components undergo a rapid cross-linking reaction, forming a three-dimensional polymer network that transitions from liquid to solid state.
4. Anchoring Interface Structure
After curing, the resin fully fills the gap between the anchor rod and borehole wall, forming a “rock – resin – anchor rod” integrated load-bearing system.
FAQ
Q1: What environments is resin anchor agent suitable for?
It is suitable for dry, humid, and partially water-bearing conditions. For high-water-pressure environments, a waterproof formulation is recommended.
Q2: Can curing time be customized?
Yes. Fast, medium, and slow curing formulations can be customized according to project requirements.
Q3: Does it require special equipment for installation?
No. Standard drilling rigs and anchor installation equipment are sufficient.
Q4: Can it be used in low-temperature environments?
Standard products work above -10°C. Low-temperature resistant formulations are available for colder conditions.
Q5: Is the anchoring strength stable over time?
Yes. Once cured, the structure maintains stable long-term performance with minimal strength degradation.
