Silicon Dioxide CAS 7631-86-9 In Paints

CAS No.7631-86-9 H-305 Silica dioxide

Do you know what the properties of silicon dioxide are?

* Physical and chemical properties:

Silicon dioxide is also called silica, with the chemical formula SiO2. There are two types of crystalline silicon dioxide andamorphous

silicon dioxide in nature.Due to different crystal structures, crystalline silicon dioxide is divided into three types: quartz, tridymite

and cristobalite.Pure quartz is a colorless crystal, and large, transparent prismatic quartz is called crystal. If the crystal contains trace

impurities,it has different colors, such as amethyst, tea crystal, black crystal, etc. Ordinary sand is a fine quartz crystal, with yellow sand

(more iron impurities) and white sand (less impurities, purer).

* Chemical properties

The chemical properties are relatively stable. It is insoluble in water and does not react with water. It is an acidic oxide and does

not react with general acids. Gaseous hydrogen fluoride reacts with silicon dioxide to form gaseous silicon tetrafluoride. It reacts

with hot concentrated strong alkali solution or molten alkali to form silicates and water. It reacts with various metal oxides at high

temperatures to form silicates. It is used to make quartz glass, optical instruments, chemical utensils, ordinary glass, refractory

materials, optical fibers, ceramics, etc. The nature of silicon dioxide is inactive. It does not react with halogens other than fluorine

and hydrogen fluoride, hydrogen halides, sulfuric acid, nitric acid, and perchloric acid (except hot concentrated phosphoric acid).

High transparency economic paint silica Matting Agent is a specialized additive used in the formulation of paints and coatings to enhance

certain properties while maintaining transparency. It typically contains silica particles that provide a matting effect, reducing glossiness and

giving the surface a more subtle, velvety appearance without compromising light transmission.

Key features of this agent include:

1. Silica Matting: The silica particles within the agent create a controlled level of opacity, providing a non-glossy finish without 

the use of heavy fillers that could compromise the paint's clarity. This can result in a smoother, more durable, and aesthetically pleasing finish.

2. Application Compatibility: The matting agent is formulated to work well with various types of paint formulations, including  water-based,

solvent-based, and UV-cured systems, ensuring compatibility across different manufacturing processes.

3. Performance Enhancements: In addition to its aesthetic benefits, the agent may also contribute to improved paint properties like better scratch

resistance, hiding power, and adhesion to the substrate.

4. Environmentally Friendly: Many high transparency economic paint matting agents are designed to meet or exceed environmental regulations,

making them a sustainable choice for manufacturers.

5. Economic Efficiency: It is designed to be cost-effective, meaning it can be used in large quantities without significantly increasing the overall

paint cost, making it an attractive option for manufacturers looking to balance performance with budget constraints.
