UV stain-resistant paint resin FSP8668.

With the development of the times, 3C electronic products update iteration speed up, consumers on the appearance of the product is also increasingly demanding, in addition to beautiful color and comfortable feel, but also requires excellent scratch resistance on the surface, while expecting the product surface with anti-fingerprint, anti-graffiti performance, when used, the product surface is not easy to leave fingerprints and other traces, or even if left traces are easy to be erased.
for the application of UV anti-fouling paint, Runo Chemical has specially developed six-cell fluorosilicon modified acrylic - FSP8668. Runo Chemical Technology Center has done a series of complete tests on the resin

. The formula adopts resin with a small amount of monosome, the appropriate amount of trigger agent, mainly investigates the resin anti-graffiti, persistence, light-dewatering powder dispersion, water-resistant cooking, toughness.
do you make light-cured
good anti-graffiti performance in the light-resistant 1-anti-graffiti system? The anti-fouling effect of lotus leaves has inspired us by the nanofiber construction on lotus leaves, which makes water droplets less wet. Based on this concept, we have developed and synthesized resins that form nano-microscopic rough structures on the surface to meet the need for coating anti-graffiti effects. The anti-graffiti performance characteristics of the coating surface mainly have contact angle and oil resistance pen test FSP8668 chain end has fluosilicon structure, and the main chain resin is not compatible will migrate to the surface, forming nano microscopic rough structure, improve the hydrophobic properties of the coating surface, to achieve anti-graffiti effect. The use of FSP8668 can greatly improve the water contact angle, in the test of oil-resistant pen, you can see the oily pen graffiti traces have obvious oil reduction situation, pen marks can be easily wiped out. Place the graffiti substrate in a 60C oven and bake for 30 minutes before the pen marks can still be erased.
many coating effects in
electronic products require a flat or matte effect, so the coating system will be added to the anti-light powder or wax paste to eliminate light. In the experiment, we also examined the effect of the addition of anti-light powder in the formula on the anti-graffiti resistance of UV coating. In a scheme with only fluorine-containing additives added, the performance of the oil-resistant pen of the finished paint film was significantly reduced. The FSP8668 as the main resin scheme, in low gloss can still maintain good oil resistance pen performance. Therefore, in the lighting system, the use of FSP8668 can also obtain a better anti-graffiti performance, at the same time, the resin has excellent anti-light powder dispersion performance, paint film surface fine, gloss is the same, no flowering, has a smooth feel.
3-persistence
There are many anti-fouling coatings on the market today that add inorderable nanoparticles (TiO2, SiO2, ZnO, etc.) or silicon fluorine additives to improve the coating's graffiti resistance, but inororated nanoparticles once coated, between the coating and air interface parts have a role; While FSP8668 participates in network crosslinking, the fluorosilicon structure is anchored in the coating, and the resistance to graffiti is more durable.

the resin is a six-nel resin, cured into a film after cross-linking network dense, with better hardness and wear resistance. In a good hardness and rigidity at the same time, with excellent toughness, thick coating paint film does not crack, has a better impact resistance.
5 to water-resistant
. FSP8668 has excellent water resistance, boiling water for 1 hour, paint film adhesion has not decreased. At the same time, we use high temperature and high humidity test to observe the change of coating oil resistance pen performance. The test scheme using fluorine-containing additives alone dropped the contact angle significantly after high temperature and humidity, and the resistance to graffiti decreased. Under high temperature and humidity, the coating surface is easily damaged, and fluorine-containing additives are easy to migrate, resulting in a significant decrease in anti-fouling performance. And the use of FSP8668 program, at high temperature, high humidity or water-resistant boiling, can still maintain a high water contact angle, with good anti-graffiti performance.
