Single-unit polyurethane Acrylic Unitedryl R7162.

Thinners in traditional spray coatings account for a large proportion, the main role of which is to reduce the viscosity of the system to meet the needs of the spraying process. Nowadays, the country pays more and more attention to environmental protection, and has also introduced a lot of policies on the control of paint VOC. Reducing the use of organic solvents has become an irreversible trend, and high-solid and low-stick coating systems will become the mainstream

.
in UV coating formulation system, high-solid and low-viscosity resins or low-viscosity acrylic monogies can be used to reduce the viscosity of the system. However, due to the low molecular weight of the monosome, after curing into a film, the paint film flexibility deviation, so the use of too many monosomes, will cause adverse effects on the paint film. In response to this problem, Runo Chemical has specially developed a single-unit polyurethane acrylic resin Unicryl R7162.
The Unicryl R7162 has a very low viscosity (14cps@25 degrees C) and is compatible with other resins, effectively reducing the viscosity of the coating system. The straight chain structure and resin properties make it have excellent flexibility and low shrinkage characteristics, when the amount of addition can improve the flexibility of the paint film.
addition to its adhesive and flexible effects, unicryl R7162 is characterized by outstanding adhesion. After extensive adhesion testing, the resin has excellent adhesion to metal (magnesium aluminum alloy, horse mouth iron) plastic substrate (PC, PET, PMMA, PS, etc.) as well as glass. This is because Unicryl R7162 has a very good wetting of the substrate, there are more chain segments penetrate into the substrate, forming a network crosslink, some polar groups of resin in the substrate surface to form hydrogen bonds and chemical bonds, so that it is easy to obtain better adhesion.
combined with the physical characteristics of the Unicryl R7162, its application is relatively wide. Can be used for ink system, improve the adhesion to hard-to-attach substrate, adjust the viscosity of the system. In UV metal coil coating as an auxiliary resin added to meet the test requirements of T-bend adhesion, impact resistance, cup protrusion, etc., has a good processing performance; In addition, Unicryl R7162 can also be used in glass coatings, adhesives, meth adhesives and other fields.
addition, unicryl R7162 has low viscosity, outstanding adhesion, good flexibility, low shrinkage and other physical characteristics, I hope this product can meet the actual needs of everyone, to solve the problems encountered in coating applications.
