Acrylic resins used in adhesives and acrylic resins used in coatings differ in the following aspects: 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. Acrylic Resins for Coatings Monomer Selection In addition to commonly used acrylate monomers, monomers with specific functions are selected to improve coating performance. For example, fluorinated acrylate monomers can improve the water resistance and stain resistance of coatings. Additive Use Pigments, fillers, dispersants, leveling agents, defoamers, etc....

1. Excellent Adhesion The polymer structure of water-based acrylic emulsion facilitates the flow and wetting of molecular chains on the substrate surface, resulting in close contact between the coating and the substrate molecules, achieving high adhesion. 2.High Pigment and Filler Loading Capacity, Significantly Reducing Costs Water-based acrylic emulsion has excellent filling properties, allowing the total solid content of the coating formulation to reach 60%. The ratio of resin to filler can reach 1:2, significantly reducing the formulation and application costs of water-based wood coatings. 3. Zero VOC, Safe and Environmentally Friendly Water-based acrylic emulsion itself contains no VOCs and can form a film at room temperature without the need for film-forming additives. Coatings using this formulation can have zero VOC content. 4. Excellent Water Resistance Water-based acrylic emulsion does not contain the surfactants used in ordinary acrylic emulsions and has specially designed hydrophobic groups. Therefore, water-based acrylic emulsion has excellent moisture resistance, preventing water molecules from penetrating the substrate after the paint film dries, achieving waterproof and moisture-proof effects. 5. Excellent Weather Resistance The molecular structure of water-based acrylic emulsion uses UV-stable monomer structures.  Furthermore, the emulsion is specially designed to allow for thorough and uniform dispersion of TiO2, reducing the impact of ultraviolet light on the emulsion and effectively protecting the substrate. 6. Excellent Pigment Dispersion Water-based acrylic emulsion has good compatibility with various water-based color pastes, maximizing the function of fillers and pigments, resulting in vibrant coating colors.

As an adhesive or coating, acrylic emulsion can be used as a binder for fiber bonding in the production process of ceramic fiber paper. In the production process of ceramic fiber paper, acrylic emulsion is used as a binder for fiber bonding, mainly for the following reasons: Good bonding performance Acrylic emulsion has excellent bonding strength and can effectively bond ceramic fibers together to form a stable structure. The polar groups in its molecular structure can interact with the surface of ceramic fibers, enhancing the bonding effect. High temperature resistance Ceramic fiber paper is usually used in high-temperature environments. After appropriate modification, acrylic emulsion can have good high-temperature resistance, maintaining its bonding performance under high-temperature conditions and ensuring the structural stability of the ceramic fiber paper. Chemical corrosion resistance Acrylic emulsion has good chemical corrosion resistance and can resist the erosion of chemical substances that the ceramic fiber paper may come into contact with during use, extending the service life of the paper. Environmental friendliness Acrylic emulsion is a water-based emulsion with water as the dispersion medium, making it environmentally friendly and meeting the environmental requirements of modern industry. It reduces the use of organic solvents and lowers environmental pollution. Film-forming performance Acrylic emulsion has good film-forming properties and can form a uniform thin film on the surface of ceramic fibers, wrapping the fibers and improving the strength and water resistance of the paper. In summary, acrylic emulsion has become a commonly used adhesive in the production of ceramic fiber paper due to its advantages in bonding performance, high-temperature resistance, chemical corrosion resistance, environmental friendliness, and film-forming performance.
