Application Scenario：

Primarily used for concrete structure crack repairs or grouting operations, it's applied to seal cracks and bond the base; during steel encasement operations, it seals around the steel plates.

—— PRODUCT ADVANTAGES ——

High Strength

Effectively prevents the recurrence of cracks.

Strong Bonding Strength

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

Excellent Thixotropy

Non-flowable during overhead and vertical surface construction.

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.
