1, Sterilization is very broad-spectrum, long-lasting, with new slow-release technology, no loss, good effect.

2, Very low toxicity, easy to operate, can be added in any process.

3, Applicable pH range is wide, 5-9 can be used.

4, Small particle size, uniform dispersion, no VOC, heat stable.

5, Non-combustible, easy to transport, convenient to use, stable under strong UV and acid rain conditions.

6, The results of outdoor weathering experiments for up to five years have proved the good effect.











Silica Nanocomposite (SNC)
According to a recent report, using a new and high-performance particle synthesis method followed by organic surface modification technology, a versatile silica nanocomposite (SNC) is obtained, which contains colloidal silica particles , The diameter is about 20nm. Tests show that it has a very narrow particle size distribution,
monodispersity, and non-agglomeration. It is a composite material enhanced by nanotechnology. The composite material added to the varnish can not only obtain a completely transparent coating film, but also greatly improve the abrasion resistance and hardness of the coating film. Even when the amount of silica added reaches more than 30%, it can still obtain low viscosity and low viscosity. A transparent mpi micronized wax paint product that produces sedimentation. According to reports, the silica nanocomposite material uses common raw materials and can be applied to all types of coatings for high-performance applications. The following describes its rheology and application effects.
(1) Rheological properties comparison The rheological properties of the composite material containing colloidal silica nanoparticles and the aforementioned fumed silica are compared. Using polyether tetraacrylate (SR-494) as the base material, the experimental samples with different SNC colloidal silica content and the comparison samples with different fumed silica content were prepared. Figure 13-31 shows the change of the viscosity of the experimental sample and the control sample with different silica content.

Figure 13-31 clearly shows that compared with fumed silica, colloidal silica greatly limits the increase in resin viscosity. 30% fumed silica content produces a resin viscosity increase of 50%. % The increased value of resin viscosity caused by the content of colloidal silica, so the latter can be used to obtain a low-viscosity coating system.
(2) Wear resistance Take the application of nanocomposites as wear resistance agents in radiation-cured acrylic coatings as an example. According to reports, in the coating, SNC colloidal silica content of 60% can still achieve the same transparency as the original resin.
