Feature
Silicon oxide powder, also known as Silica Powder, is a commonly used additive in water-based coatings. It is primarily
used to improve the mechanical properties, such as hardness, scratch resistance, and durability, of the coating film.
Silicon oxide powder is composed of silicon and oxygen atoms arranged in a lattice structure. It is available in various
particle sizes, ranging from nanometers to micrometers, depending on the desired application and performance
requirements.
When added to water-based coatings, silicon oxide powder acts as a reinforcing filler, enhancing the overall performance of
the coating. It improves the adhesion of the coating to the substrate, reduces the coefficient of friction, and increases the
abrasion resistance of the film.
Additionally, silicon oxide powder can also improve the anti-blocking properties of water-based coatings, preventing the coated
surfaces from sticking together when in contact for an extended period.
In terms of application, silicon oxide powder can be easily dispersed in water-based coating formulations using mechanical agitation
or high-speed mixing equipment. The powder can be added directly to the coating formulation during the manufacturing process or
as a post-addition to already formulated coatings.
Overall, silicon oxide powder is a valuable additive for water-based coatings, offering improved mechanical properties, enhanced
adhesion, and increased durability. Its versatility and compatibility with various coating systems make it a popular choice for many
coating applications.
USING TIPS:
* Recommend dosage is 3%-8%. (Please adjust the dosage according to the actual product.)
* As different formulations and conditions, suggest the user to test and make sure the dosage before using.
