The role of plasticizers in glue

1. Improve bonding strength

The introduction of plasticizers can enhance the bonding strength of glue. Plasticizers can change the molecular structure of glue. Adding appropriate plasticizers to glue can increase the contact area between glue and the surface of the adherend, increase the contact area, and thus improve the bonding strength. The role of plasticizers can make the glue better penetrate into the tiny concave and convex surfaces of the adherend, so that a stronger bond can be achieved, the adhesion between the glue and the adherend can be improved, and the bonding can be more stable and reliable.

2. Improve fluidity

Plasticizers can improve the fluidity of glue. In some cases, the viscosity of glue may affect the effect of construction. The right amount of plasticizer can reduce the viscosity of glue, making it easier to apply, fill and coat. This helps to improve the construction performance and coating uniformity of glue.

3. Enhance durability

The durability of glue is crucial to the durability of the bonding effect. Plasticizers can improve the durability of glue and keep its stable performance in different environments and conditions. Plasticizers in glue can reduce the risk of glue losing adhesion due to moisture, temperature changes and other factors, and extend the service life of bonding.

4. Adjust hardness

Different glues may have differences in hardness, and the addition of plasticizers can adjust the hardness of glue to a certain extent. By properly selecting the type and amount of plasticizer, the glue can be made more in line with specific application requirements, meeting both the strength requirements of bonding and the characteristics of the bonded objects.

5. Improve ductility

Plasticizers can reduce the viscosity of glue, making it develop from a high viscosity state to a low viscosity state, and improve the fluidity and spreadability of glue. This will make it easier for the glue to form a uniform film on the surface of the material and improve the bonding effect.
