High wear-resistant aromatic polyurethane acrylic - FSP8293.

Nowadays, UV coating technology has become more and more mature, and the two most important roles of coating is decoration and protection, a variety of coating processes have also been born, performance requirements are constantly improving. In many applications, the need for lacquer film has a certain rigidity, especially high-end wood paint, PVC varnish, hardening fluid and other fields of wear resistance, scratch resistance has high requirements. The traditional high-level high-level energy adipose polyurethane has good comprehensive performance, has a certain toughness, but its rigidity and resistance may not be able to meet the high wear requirements of

.
, according to market demand, specially developed six-power aromatic polyurethane acrylic - FSP8293. We have done a series of complete tests for this product, directly using a simple test formula of resin with trigger, mainly to investigate the resin wear resistance, adhesion, curing speed, water cooking resistance, color display, toughness and other properties. Experiments show that FSP8293 has the following characteristics.
cure speed is
. FSP8293 curing speed is very fast, measured, in 150mJ/cm2 energy can be table dry, high reaction activity, cross-linking network dense, in the high film thickness also has excellent deep curing performance. Practical application with a small number of low-level monoliths or resins, can reduce shrinkage stress, at the same time has a wide construction window, suitable for a variety of construction processes.
wear resistance is
. FSP8293 pencil hardness on PC substrate up to H@1kgf, high cross-link density not only makes the paint film has a high hardness, but also gives the paint film excellent wear resistance. The test formula does not add any additives, in the aerobic state of light curing into a film, the use of 0000 steel velvet to test the curing film, weight 1kg weight, back and forth friction 300 times, paint film surface completely unmarked. RCA paper tape wear test, weight 175g, friction 500 laps, paint film has not been worn through, and the wear marks are shallow. These tests reflect the resin's excellent rigidity, outstanding wear resistance, suitable for a variety of applications with high wear performance requirements.
Toughness
Many six-erythroid resins, especially high-level resins with more than nine-degree ability, are generally brittle, poor cracking resistance, in the formulation design is difficult to balance bending performance and wear resistance. FSP8293 in the structural design by the aromatic ring to improve rigidity, while introducing a certain flexible chain segment, so that it has excellent tenacity. FSP8293 coating film curing table dry, continue to use UV exposure, energy in 4000mJ/cm2, the paint film will not crack, has a better anti-cracking performance, so the resin is also suitable for use in some thick coating system applications.
Water-resistant cooking
in high-end applications will have water-resistant cooking performance testing requirements, many senior market officials can resin testing water-resistant cooking test alone, due to large volume contraction, resulting in a significant decline in adhesion after boiling. FSP8293 in the test can be boiled by boiling water for an hour, the surface of the paint film no change, no foaming, adhesion did not decrease. Under the condition of high temperature and high humidity test, it can also maintain good tightness. The resin fully meets the testing requirements for water and moisture resistance in high-end applications.
's
. FSP8293 has a good leveling, plumpness, large area spraying, up to mirror leveling, at the same time has a good resistance to oil, no hemp points, shrink holes. Because the resin has aromatic ring structure, anti-yellowing performance is not as good as fat family six-ability resin, so it is suitable for some applications that are not required to resist yellowing, such as wood, wood flooring, ink and so on.
