Application Scenario：

1.Injection sealing repairs for cracks in concrete bridges, buildings, waterworks, and road surfaces;
2.Reinforcement injection repairs for internal concrete defects like honeycombing and looseness;
3.Fiberglass anti-corrosion and structural surface coating for protection;
4.Suitable for grouting and bonding gaps in concrete and brick structures to achieve crack repair and reinforcement objectives.

—— PRODUCT ADVANTAGES ——

High Strength

Resilient and suitable for seismic strengthening.

Excellent Flowability

Can fill every void adequately.

Strong Bonding Strength

Ensure that bonded areas can endure stress and loads over the long term.

Good Durability

Resistant to chemical corrosion such as acid, alkali, salt, and harsh environments (non-toxic itself).

EXCLUSIVE FORMULA

1.WONSTAR Bonding Adhesives use nanoscale raw materials with extremely fine particles, and we also incorporate anti-flow control agents to give the adhesive excellent thixotropic properties.
2.In the adhesive formulation, we introduce hydrophilic and hydrophobic groups, allowing the adhesive to maintain outstanding bonding capability in both humid and dry environments.
3.The product also include defoaming agents to ensure that no bubbles are generated in the adhesive, preventing any impact on its strength.
4.To compensate for the epoxy resin's lack of toughness, we introduce elastic reactive spheres into the formulation, enhancing the adhesive's impact resistance and long-term performance.
