Construction adhesives are essential materials in building projects and have a wide range of applications. During building decoration and renovation, they are primarily used for bonding panels and preparing wall surfaces; they enhance properties such as water resistance, sealing, and elasticity, thereby improving aesthetics and comfort, while also optimizing construction techniques and boosting the efficiency and quality of the work.

Shandong propylene oxide price rebounded sharply from a low level. As the key raw material for sealants, its price surge brings cost pressure to adhesive industry. Manufacturers monitor raw‑material changes and optimize supply chain to ensure stable quality and supply.

When using an adhesive to bond an object, the desired result is sometimes not achieved, and surface preparation is a major factor; indeed, the success or failure of the bond often hinges on how the surface is treated. During use, objects inevitably accumulate contaminants; if these are not thoroughly cleaned off prior to bonding, they interfere with intermolecular forces and result in a weak bond. So, how exactly should surface preparation be carried out before applying the adhesive?

The curing reaction of an adhesive is a process—involving chemical reactions such as polymerization and cross-linking—by which properties like bond strength are developed and enhanced. Curing is a critical step for achieving optimal bonding performance; maximum strength is attained only upon complete curing. The curing process is categorized into initial curing, primary curing, and post-curing.

Common adhesives for renovation include silicone sealant, PU adhesive, nail‑free adhesive, PU foam and marble glue.Each has its own applicable scenarios and limitations. Choosing the right adhesive ensures good construction results.

Construction adhesives are used in every stage of the construction process and with virtually every type of material. They also find application in areas such as road marking, dam waterproofing, emergency repairs for military projects, and leak sealing. Consequently, the scope of their application is extremely broad.

Adhesive consumption in my country is projected to continue growing at a rate of 8%–10%, with development trends falling into six major categories.

Adhesives are generally defined as natural or synthetic, organic or inorganic substances capable of joining two or more components or materials together through mechanisms such as interfacial adhesion and internal cohesion. Variations in the primary constituents of adhesives result in differences in their properties and fields of application.
