It is formed byemulsion polymerization of styrene, acrylic acid and ester monomers, combined with self-crosslinking monomers, fluorine monomers, additives and special
2. Performanceand applications:
PEC-539 hydrophobic emulsion can be combined with pigments, fillers, color pastes and
additives to form environmentally friendly, non-toxic and hydrophobic coatings. It can also be used as a cover to enhance the waterproof performance and durability of the bottom layer. After the emulsion is formed into a film, it has excellent waterproof performance, excellent hydrophobic performance and excellent stain resistance.
4.Why are lotus leaves hydrophobic and not wetted by water?
There are countless micron-sized waxy papillae structures attached to the surface of the lotus leaf, and the surface of each micron-sized papilla is attached to the surface of many nanoscale particles similar to its structure. Scientists call this the micron-nano dual structure of the lotus leaf. It is these tiny dual structures that make the contact area between the surface of the lotus leaf and water droplets or dust very limited. Therefore, the phenomenon of water droplets rolling on the leaf surface and taking away dust occurs, and the water does not remain on the lotus leaf. leaf surface.
For example, the surface of the lotus leaf under the electron microscope seems to be covered with "hills" that are raised one after another. They are covered with hairs, and a steamed bun-shaped "bunker" convex top grows on the top of the "hills". , as if one tentacle after another protects the leaf surface, making it impossible for anything larger than it to get close to the leaf surface. The existence of this milky structure makes the depression between the "hills" filled with air, so that it is close to the leaf surface. An extremely thin layer of air is formed on the leaf surface, only nanometers thick. This means that after dust, rainwater, etc., which are much larger than this structure in size, fall on the leaf surface, they can only form a few points of contact with the convex tops of the "hills" on the leaf surface through an extremely thin layer of air. Raindrops form spherical shapes under the action of their own surface tension. The water balls absorb dust during rolling and roll out of the leaf surface. This is the secret of the "lotus leaf effect" that can self-clean the leaf surface.
