Segmental Construction Adhesive - Wonstar Construction

Segmental Construction Adhesive

This product's A and B components are both packaged in plastic drums.

Component A: 10kg/drum Component B: 5kg/drum

It is a dual-component modified epoxy resin adhesive, characterized by high compressive strength, good bonding performance, long working time, thixotropy, and excellent anti-flow properties. It is suitable for the splicing of concrete prefabricated components such as bridges and wind turbine towers.

Application Scenario：

1.Bridge prefabricated segment joints;
2.Assembly of prefabricated building sections.

—— PRODUCT ADVANTAGES ——

High Strength

Possesses excellent impact resistance.

Strong Bonding Strength

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

Extended Workability Period

Rapid curing with a quick increase in strength.

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.
