Feature
The CAS number 7631-86-9 corresponds to silicon dioxide (SiO2), a common compound used in various applications,
including e-coating (electrophoretic coating). When seeking high-grade silicon dioxide for e-coating, you'll want to prioritize
certain characteristics to ensure optimal performance and durability. Here's what to consider:
Purity: High-grade silicon dioxide should have a high level of purity to minimize impurities that could affect the quality and
performance of the e-coating. Look for products with specifications indicating high purity levels.
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 silicon 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 silicon dioxide powder is UV stable to prevent degradation or discoloration of the e-coat over
time when exposed to sunlight. UV-stabilized silicon dioxide particles help maintain the appearance and performance of the
coating, particularly for outdoor applications.
Chemical Resistance: High-grade silicon 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: Silicon 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 silicon 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.
When selecting high-grade silicon dioxide for e-coating, it's essential to verify that the product meets relevant regulatory standards
and safety requirements for use in e-coat formulations. Consulting with suppliers for product recommendations and conducting
compatibility testing can help determine the best high-grade silicon dioxide for your specific e-coating needs.
