    In recent years, many consumer electronics coating process has been technology constantly new, not only on the appearance of the effect has higher requirements, but also pay more attention to the surface performance of the coating. Coating anti-graffiti, anti-fingerprint effect is currently one of the more popular material requirements, the main resin will generally use silicon modified resin or fluorine modified resin to meet the requirements of anti-fouling. Previously introduced for the matte system of the six-level fluorosilicon modified acrylic FSP8668, access to a good market response
    China
    .
    recently, the application of bright light and anti-fouling has gradually increased, there are high requirements for the surface. Therefore, Runo Chemical Technology Center for bright light applications developed a three-degree fluorosilicon modified acrylic - FSP8638. 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, mainly investigates the resin's anti-graffiti resistance, persistence, leveling, water-resistant cooking, wear resistance, toughness and so on.
    1.
    anti-graffiti
    FSP8638 is a fluorosilica modified resin, high water contact angle, in the test of oil-resistant pen, oil-resistant pen graffiti traces have obvious oil shrinkage, pen marks can be easily erased, and the coating surface has no trace residue. After we put the graffiti substrate in a 60C oven, after 30 minutes of baking, the oily pen marks have been completely dried, at this time with a dust-free cloth can still easily remove traces. Experiments show that FSP8638 has excellent anti-graffiti performance.
    It's good toughness
    Now many 3C consumer electronics on the coating of toughness requirements, especially on mobile phone applications have bending testing, and many fluorine modified or silicon modified resins on the market are high-level resin, high cross-link density is more conducive to anti-graffiti, fingerprint resistance and other requirements, but also will make brittle increase, do the main resin bending easy to collapse paint or adhesion drop. FSP8638 is a three-function resin, the main chain is polyurethane, the side chain uses fluorosilicon modified chain segment, so that you can obtain excellent toughness, and three-function energy can also provide a good cross-link density, low volume shrinkage, taking into account good wear resistance.

    Persistence
    persistence of anti-fouling effect is also an important material indicator, by adding silicon fluorine additives to improve the coating of anti-graffiti solutions, often poor durability, small molecule additives easy to migrate resulting in a significant reduction in anti-fouling effect. The FSP8638 chain contains a fluorosilicon structure, which, because it is incompatible with the main chain and has a low proportion, makes the fluorosilicon structure naturally migrate to the coating surface when coated to form nanosystructure microstructures to achieve anti-fouling effect, such anti-fouling effect is more durable. At the same time, FSP8638 has better compatibleity than some fluorine modified resins.
    at the same time through acrylic double bonds to anchor the fluorosilicon structure in the coating three-dimensional network structure, compared to fluorosilicon additives, it is clear that durability will be greatly improved, even if the surface is worn for long-term use, there will still be good anti-fouling performance.

    Water resistance
    water-resistant cooking test is also one of the general performance requirements, anti-fouling paint in the boiling or high temperature and humidity test, the water contact angle will be reduced, especially with additives, after boiling the anti-fouling effect will be significantly reduced. FSP8638 has excellent water resistance, boiling water boiling for 1 hour, paint film no change, adhesion has not decreased, do marker pen test, there is still a phenomenon of oil shrinkage, pen marks can be erased.
    5
    flow flatness For the application of bright light system, first of all, it needs to have excellent surface performance, for the main resin leveling, plumpness, wetting has a higher requirement. FSP8638 molecular weight is not high, low viscosity, good wetting, can achieve mirror leveling effect, while better resistance to oil, help to improve the yield.
