Feature
OK520 is a type of Matting Agent silica specifically designed for coatings. Here's some information about OK520:
Matting Agent: OK520 is primarily used as a matting agent in coating formulations to reduce glossiness and create a matte
finish on surfaces. It achieves this by scattering light, resulting in a softer, non-reflective appearance.
Easily Dispersible: OK520 is known for its excellent dispersibility in coating formulations. This ensures uniform distribution
of the matting agent throughout the coating, leading to consistent matte appearance across the surface.
High Purity: OK520 is manufactured using high-purity silica, which ensures that it does not introduce impurities that could
affect the coating's performance or appearance.
Particle Size and Structure: The particle size and structure of OK520 are carefully controlled to achieve the desired level
of matting effect without compromising other coating properties such as clarity or smoothness.
Surface Modification: OK520 may undergo surface modification to enhance its compatibility with various coating resins and
improve its dispersibility in different types of coating formulations.
Abrasion Resistance: Coatings containing OK520 typically exhibit improved abrasion resistance, making them more durable
and suitable for applications where surface wear is a concern.
UV Stability: OK520 may provide some degree of UV protection to coatings, helping to prevent color fading and degradation
caused by exposure to sunlight. This is particularly important for outdoor applications.
Versatility: OK520 can be used in a wide range of coating formulations, including water-based and solvent-based systems,
making it suitable for various substrates and applications.
When using OK520 in coating formulations, it's essential to follow the manufacturer's recommendations regarding dosage
levels, dispersion methods, and compatibility with other additives and resins. Conducting thorough testing and evaluation of
the coating's performance is also recommended to ensure that the desired matte finish and other properties are achieved
consistently in the final product.
Tips:
* Before you use it, please test and make sure the dosage before using according different formulations and conditions.
* Recommended dosage is 3% -5%.
