Water-based acrylic emulsion

Water-based acrylic emulsion is an acrylic resin emulsion using water as the dispersion medium. It belongs to water-based acrylic resin organic compounds and is one of the core materials for water-based coatings.

First, Basic Information

1. Preparation: Primarily synthesized by emulsifying oil-based olefin monomers in water and initiating the reaction with water-based free radical initiators.

2. Appearance: Typically a white milky liquid.

3. Particle Size: The emulsion exhibits larger particle sizes, conferring unique physical and chemical properties.

Second, Product Types

Water-based acrylic emulsions can be categorized by monomer composition into types such as pure acrylic, styrene-acrylic, and silicone-acrylic. Each type possesses distinct characteristics to meet diverse requirements.

1. Pure acrylic emulsion: Polymerized from acrylic ester monomers, it offers excellent weather resistance, high gloss, and strong water resistance. Widely used in high-quality coatings and adhesives.

2. Styrene-Acrylic Emulsion: Copolymerized from styrene and acrylic monomers, it offers relatively lower cost while combining styrene's rigidity with acrylic's flexibility. It exhibits excellent water resistance, alkali resistance, and adhesion, commonly used in architectural coatings and paper coatings.

3. Silicone-Acrylic Emulsion: Incorporates organosilicon groups into the acrylic polymer chain, significantly enhancing weather resistance, water resistance, stain resistance, and high-temperature tolerance. Suitable for exterior wall coatings and industrial protective coatings requiring superior weather resistance.

Third, Key Characteristics

1. Environmental Friendliness: Utilizing water as the dispersion medium with minimal or no organic solvents significantly reduces volatile organic compound (VOC) emissions. This eco-friendly formulation meets environmental standards and has gained widespread adoption in today's green-conscious era.

2. Excellent Film-Forming Properties: Capable of drying and forming a film at room temperature, the resulting coating exhibits good gloss, flexibility, and hardness. During film formation, as water evaporates, emulsion particles coalesce to create a continuous film, providing protection and decoration for the coated object.

3. Weather and Chemical Resistance: Exhibits good UV resistance and chemical resistance. Maintains stable performance under varying climatic and chemical conditions, resisting fading, chalking, or chemical erosion, thereby extending coating lifespan.

4. Strong Adhesion: Demonstrates excellent adhesion to diverse substrates including wood, metal, plastic, and cement. It bonds firmly to substrate surfaces without peeling, ensuring coating integrity and protective efficacy.

5. Low Viscosity and High Solids Content: Achieves high solids content at low viscosity, facilitating application and enhancing efficiency. This also reduces coating consumption and lowers costs.

Fourth, Storage and Transportation

1. Storage: Store in a cool, dry, well-ventilated warehouse, avoiding direct sunlight and environments with excessively high or low temperatures. Recommended storage temperature is typically between 5–35°C to prevent emulsion freezing or demulsification.

2. Transportation: Avoid collisions and severe vibrations during transport to prevent packaging damage and emulsion leakage. Additionally, protect against rain, sunlight, and moisture to ensure product quality remains unaffected.
