Polyurethane composite coating crosslinking agent
Alicyclic diamine is the industry standard of the high performance epoxy crosslinking agent, used for industrial floor coatings, Marine and anti-corrosion coatings, moreover, it is also used in high performance composite materials.
Its application range covers all major processing areas, such as resin transfer molding process (RTM), wet process molding and drawing process. Epoxy coatings because of their excellent mechanical properties and corrosion resistance, commonly used in coating and the coating formula, its tolerance is very persistent, also have good adhesion to various base material.
The light-stabilized polyurethane system is a fatty group of diisocyanate monomer and polyisocyanate cross-linking agent for high performance polyurethane coating
VESTANAT ? as one-component two-component thermosetting polyurethane coating resistance to yellowing of the crosslinking agent, can promote coatings in various applications and system performance, it can effectively improve the chemical character of coating system and improve the flexibility of the pre-coated metal coating.
In particular, the use of crosslinking agent can obtain the high glass transition temperature (Tg) and the coating fastness.
The product can be used in solvent, water and solvent-free (powder coating) coating system. IPDI is characterized by good compatibility with commonly used coatings, and the prepolymer viscosity is low. H12MDI also has strong chemical resistance and excellent mechanical properties in PUD and TPU applications. TMDI also has excellent compatibility and excellent performance in improving the flexibility of UV resin.
Chen et al., using a simple method for preparation of the super hydrophobic surface of polyvinyl chloride (PVC), porous coating on the surface of the contact Angle is 154 ° is plus or minus 2.3 °, rolling Angle 7 °. The porous polyvinyl chloride (PVC) coating in the pH = 1 ~ 13 and 5 ~ 50 ℃ or outdoor exposure 30 d contact Angle can keep above 150 °, has a good super hydrophobic self-cleaning performance.

Lee and others adopt simple, high efficiency and high repeatable templates to prepare the surface of the ultra-hydrophobic polymer with microns and nanoscale irregular layered structures. By means of template method of heating and pressure on the surface of the thermoplastic polymer that different with super hydrophobic properties of the layered structure was prepared, the contact Angle is greater than 150 °.
Especially with nanometer fiber structure of high density polyethylene (HPDE) surface contact Angle is about 160 °, rolling Angle less than 2 °, showed good super hydrophobic property, at the same time in different organic solvents and still shows excellent stability in aqueous solution. The use of polystyrene (PS) as a thermoplastic plastic is widely used in daily life.
If the water is self-cleaning, applications will be further expanded, such as in microfluidic devices. The process of using the macroscopical and fluorinated plasma etched by the use of roughing and fluorination has produced the surface of the polystyrene (PS), which has superhydrophobic properties. The hydrophobic polystyrene is not affected by the proper surface roughness, and can be used to prepare the template of the hydrophobic surface.
Inorganic nanoparticles composite polymer self-cleaning coatings. In recent years, with the development of nanotechnology, the excellent properties of nanometer compound for the functionalization of coating provides a new train of thought and ways. Nanoparticles due to its special properties are widely used in coatings, the coating not only can strengthen the stability and mechanical properties, and can be prepared with high contact Angle of the surface of the hydrophobic self-cleaning. Inorganic nanoparticles are commonly used for the preparation of self-cleaning surfaces.
Harry, etc by mechanical blending method is added in the PRTV silicone rubber coatings hydrophobic nano SiO2 on modification, preparation of super hydrophobic composite coating water contact Angle of 106 ° c to 150 °. Dong Yunhe such as organic silicone modified polyurethane resin as matrix resin, the fluorine modified with silane as inorganic filler, nanometer TiO2 nanoparticles were prepared with self-cleaning function of aerospace coatings.
