Feature
In the context of PVC paint, a "soft hand-feeling" silica dioxide likely refers to a silica-based additive that provides softness
or a smooth tactile sensation to the coated surface. Here's how silica dioxide can contribute to achieving such characteristics
in PVC paint:
Surface Modification: Silica dioxide particles can be surface-modified to enhance their compatibility with PVC resin and
improve their dispersibility in the paint formulation. Surface modification can also influence the interaction between the silica
particles and the coated surface, contributing to the desired soft hand-feel.
Particle Size and Distribution: Controlling the particle size and distribution of silica dioxide is crucial for achieving the desired
tactile properties. Fine silica particles dispersed evenly in the paint formulation can impart a smoother surface texture and
enhance softness.
Rheological Properties: Silica dioxide can influence the rheological behavior of PVC paint, affecting its flow characteristics
and film-forming properties. Properly chosen silica additives can contribute to a smooth and uniform coating layer, resulting in
a softer feel upon drying.
Matting Effect: While traditional matting agents are used to reduce glossiness, certain types of specially engineered silica
dioxide particles can create a subtle matting effect without compromising the softness of the coated surface. These silica
particles can scatter light to minimize gloss while maintaining a smooth and soft hand-feel.
Flexibility Enhancement: In PVC coatings, silica dioxide can improve the flexibility and elasticity of the dried film. This
enhancement can contribute to a softer feel by reducing stiffness and promoting a more pliable coating surface.
Adhesion Promotion: Silica dioxide additives can enhance the adhesion of PVC paint to the substrate, ensuring better
bonding and reducing the likelihood of cracking or peeling, which could compromise the soft hand-feel of the coating.
UV Protection: Certain types of silica dioxide additives may provide UV protection to PVC coatings, preventing premature
degradation and yellowing of the coated surface. Maintaining the original appearance of the PVC paint over time can contribute
to a more pleasing tactile experience.
When selecting a soft hand-feeling silica dioxide additive for PVC paint, consider factors such as compatibility with PVC resin,
ease of dispersion, desired softness level, and regulatory compliance. Additionally, thorough testing and evaluation of the
coating's tactile properties are essential to ensure that the desired soft hand-feel is 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%.
