High Purity Silica Dioxide For Electrophoretic Paint

Feature

For electrophoretic paint (e-coat) applications, utilizing high-purity silica dioxide (SiO2) is essential to ensure optimal coating 

performance and durability. Here are some key considerations when selecting high-purity silica dioxide for electrophoretic 

paint:

Purity: Choose a silica dioxide powder with high purity to minimize impurities that could affect coating quality or cause defects 

in the e-coat. High-purity silica ensures consistent and reliable performance of the paint formulation.

Particle Size and Distribution: Fine particle size and uniform distribution are crucial for achieving a smooth and even coating 

with excellent coverage. Smaller particles contribute to better film formation and adhesion to the substrate.

Surface Modification: Surface-treated silica dioxide particles can enhance compatibility with the e-coat resin and improve 

dispersibility, adhesion, and durability of the coating. Surface modification can also influence properties such as gloss, scratch 

resistance, and chemical resistance.

UV Stability: Ensure that the silica dioxide powder is UV stable to prevent degradation or discoloration of the e-coat over time 

when exposed to sunlight. UV-stabilized silica particles help maintain the appearance and performance of the coating, particularly 

for outdoor applications.

Chemical Resistance: High-purity silica dioxide should provide excellent chemical resistance to solvents, oils, acids, and other environmental factors. Enhanced chemical resistance ensures the longevity and integrity of the e-coat in various operating 

conditions.

Adhesion Promotion: Silica dioxide additives can help promote adhesion between the e-coat and the substrate, ensuring a 

strong and durable bond. Good adhesion properties prevent issues such as delamination or peeling of the coating.

Film Thickness Control: The silica dioxide powder should allow for precise control of film thickness to achieve desired coating

thicknesses and uniform coverage. Consistent film thickness is essential for meeting performance requirements and ensuring 

quality in e-coating applications.

Regulatory Compliance: Verify that the silica dioxide powder meets relevant regulatory standards and safety requirements for 

use in electrophoretic paint formulations, particularly concerning chemical composition, toxicity, and environmental impact.
