Excellent silver row UV single coat resin - FSP5590

UV single coating is the traditional primer, paint two coating process into a coating process, compared to the traditional PU coating, greatly improve production efficiency and reduce energy consumption, in recent years, UV single coating process has been widely used in notebook coating.
in the UV single coating system, the technical threshold of single-coated silver powder paint is high, the main resin has a high material requirements, need to take into account the directional arrangement of silver powder, wear resistance, adhesion, water-resistant cooking and other properties. Unicryl R9323 has excellent comprehensive performance, as the main resin of the pen single silver paint system, has a good market response

. With the increasing maturity of UV single coating process, there are more coating applications tend to use single coating process instead of traditional two-coat process, such as power switches, set-top boxes and so on. Compared to pen and electricity, such applications require higher costs and require a more cost-effective main resin, giving more space to formulation design.
based on this market situation, the company has specially developed a cost-effective UV single coating resin , FSP5590, on the basis of the Unicryl R9323. The resin is a five-feature modified acrylic, and we have done a series of complete tests on this product. The formula uses resin with a small amount of monosome, moderate amount of trigger agent, mainly to investigate the resin's silver powder arrangement, adhesion, curing speed, water-resistant boiling, color display and storage stability and other properties. Through experiments, it can be concluded that FSP5590 has the following characteristics.
for the application of single-coated silver powder paint, the directional arrangement of silver powder is very important, directly determines whether the paint film can obtain excellent metal texture. In the test, we used a simple formula of resin, silver powder, trigger and solvent to control the surface product ratio of 0.25, spray film thickness of 12-15 m. FSP5590 cured after the silver powder directional arrangement effect is outstanding, strong metal texture, delicate feel, L value can reach about 86 degrees, can fully meet the episodural needs of single silver paint.
is a
FSP5590 molecular weight is very large, pigments and light powder has excellent wetting dispersion, has excellent de-lighting performance. After the resin is added with a small amount of anti-light powder, the gloss decreases significantly, and there will be no flowering, re-coarseness and so on. At present, the vast majority of UV single coating projects are mainly matte, FSP5590 advantage is to add only a small amount of anti-light powder can also achieve low gloss, so that the metallic effect is small, the effect is outstanding, while less light powder addition will not have much negative impact on wear resistance.
wear resistance
like most high-ranking resins, the FSP5590 serves as a five-function resin with fast curing speed, good table drying, good cross-link density and hardness. In the excellent silver powder arrangement performance at the same time, can take into account the good RCA wear resistance performance, with a small number of high-level resin, monosome or wear-resistant wax powder can achieve wear resistance requirements.
recoaring is
The FSP5590 has good hardness and wear resistance, but also takes into account the heavy coating, the volume shrinkage is relatively low, the plastic substrate adhesion is good. Resin with silver powder or pigment testing, the same can get good heavy work performance, practical application can also be paired with adhesively prominent resins such as UT59478 to further improve the re-painting performance.
is water-resistant
FSP5590 with silver powder test, boiling water for one hour, paint film surface no change, no foaming, and adhesion did not drop, there will be no silver phenomenon. Under the condition of high temperature and high humidity test, it can also maintain good tightness. The resin fully meets the test requirements for water and moisture resistance in high-end applications.
storage stability
UV single-coated silver powder paint storage stability is also one of the difficulties, due to the introduction of a lot of silver powder, the system also uses a lot of highly active triggers, storage at high temperatures easily lead to the bottom of the coating lumps. FSP5590 after special changes, its storage stability has been greatly improved, the test using FSP5590 as the main body of silver paint paint into the oven 60 degrees C baking for 7 days, there will be no cross-linking, lumps and other conditions, spraying will not appear after the appearance of blackness, back thickening, metal sense of decline and other adverse conditions.
cost
the FSP5590 is optimized in the synthesis process and the cost is strictly controlled due to the need to cover more applications. At the same time, the product has a high opening-thin ratio, which can further reduce the overall cost of the formula. The FSP5590 has excellent comprehensive performance and a certain price advantage, which I believe can meet the needs of different applications.
