UV application process in vacuum plating has been quite mature, many fields have applications, such as: automotive headlights, cosmetics, mobile phone electronics industry. However, with the continuous updating of these industry technologies, the requirements for supporting the link is also higher and higher, such as: the mobile phone market is gradually popular gradient color, this process on the UV to paint a deeper color requirements, to achieve a balance of performance and appearance.
in response to market requirements, Runo Chemical has specially developed a deep color coating resin, today for you to introduce this medium coating resin - FSP5787
. For this resin, the application laboratory with a small number of monobodies and triggers to do a series of performance tests, the specific test results are as follows:
1
curing speed
FSP5787 is a two-role modified special acrylic, compared to the other two-role resin in the same type, it has a faster curing speed, 300mJ/cm2 energy can be dried. After pigmenting, also has a very good deep curing performance, as a medium coating resin use, do not need to match too many high-level energy ingredients, can achieve a high conversion rate.
2
inter-layer adhesion
FSP5787 although fast curing, but the resin curing shrinkage is low, vacuum coating aluminum, tin have excellent adhesion, and the adhesion between the paint layer is also very excellent.
3
color display
FSP5787 pairs of color paste display effect is very excellent, colorful, high transparency. Color paste addition of more than 10% will not appear the problem of clump color, flowering, and the curing speed will not have a greater impact, ideal for deepening the color system.
4
water-resistant boiling
boiling water boiling for one hour test, paint film surface no change, no foaming, no whitening and other phenomena, and adhesion has not decreased, in high temperature and high humidity test conditions, can also maintain a better tightness.
5
Flexible
as a two-vinyl adipose family polyurethane acrylic resin, FSP5787 although fast curing speed, high hardness, but because of its low curing shrinkage, so there is still a very good flexibility, paint film on the PET film 180 degrees fold, not easy to crack.
