Performance Characteristics

Acrylic Resins for Adhesives

High Bonding Strength

Requires strong adhesion between different materials, requiring rapid curing and sufficient cohesive and adhesive strength. For example, α-cyanoacrylate adhesives can cure in seconds for rapid bonding.

Good Flexibility

When the adhered materials are subjected to external forces, the adhesive's flexibility can buffer stress, preventing easy cracking at the bonded area and ensuring the durability of the bond. For example, second-generation acrylic adhesives form a tough cured product through the reaction of monomers and elastomers.

Strong Surface Adaptability

Exhibits good adhesion to various material surfaces, including metals, plastics, glass, and wood. Surface preparation requirements for the bonded materials are relatively low; some adhesives can even bond to oil-coated surfaces.

Acrylic resin for coatings

Good weather resistance

In outdoor environments, it can resist long-term erosion from ultraviolet rays, rain, wind, sand, and temperature changes. It is not prone to fading, chalking, cracking, or peeling, maintaining the integrity and decorative properties of the coating. It is often used for coating outdoor buildings and facilities.

Excellent decorative properties

It can be made into coatings with different gloss levels, such as high gloss and matte. It offers a rich variety of colors with good color retention, providing excellent visual effects. It also has excellent leveling properties, forming a smooth and even coating surface.

Good mechanical properties

It possesses a certain degree of hardness, abrasion resistance, and flexibility to resist mechanical actions such as friction and impact during use, protecting the surface of the coated object. However, different coatings may emphasize different aspects of hardness and flexibility; for example, wood coatings may prioritize flexibility, while metal coatings may focus more on hardness.

Chemical Composition and Formulation

Acrylic Resins for Adhesives

Monomer Selection

Commonly used monomers include acrylates and methacrylates. Special functional monomers are also introduced to improve adhesive properties, such as monomers containing polar groups like hydroxyl and carboxyl groups, which can increase interaction with the surfaces of the adhered objects.

Additive Use

Initiators, accelerators, stabilizers, plasticizers, etc., are added. For example, anaerobic adhesives require a special initiation system to initiate the curing reaction under anaerobic conditions.
