Description
Silica Matting Agent is a special additive used in the coating industry to achieve a matte or flat finish in UV
(ultraviolet) coatings. It is made from a type of silica, also known as silicon dioxide, which is a naturally occurring
chemical compound.
This Matting Agent works by scattering light when it hits the coated surface, thus reducing glossiness and providing
a matte appearance. The size and shape of the silica particles in the matting agent control the level of matting effect.
Silica matting agents for UV coatings are commonly used in various applications, including wood finishes, plastic
coatings, overprint varnishes, and industrial coatings. They are preferred for their excellent transparency, easy
dispersion, and outstanding matting efficiency.
Moreover, they are also known for their resistance to weathering and chemicals, making them suitable for outdoor
applications. They can provide a smooth, soft-touch, and scratch-resistant surface, enhancing the aesthetic and tactile
properties of the coated product.
The use of silica matting agents in UV coatings also contributes to the sustainability trend in the coatings industry, as
they are free from volatile organic compounds (VOCs) and can be cured using energy-efficient UV light.
Characters
Lower Viscosity. This silica matting agent produce by unique technology and cover with special surface treatment. It
has low oil absorption, good dispersibility, excellent matting efficiency, all of which enables better scratch resistance
and deposition prevention to the film, as well as excellent hand feeling.
