Diurethane Dimethacrylate: A Versatile UV Absorber
Diurethane dimethacrylate, also known as DUDA, is a versatile UV absorber that is widely used in a variety of applications, including coatings, adhesives, and plastics. It is a specialty chemical that is manufactured and supplied by INNO Specialty Chemicals, a leading producer of high-quality chemicals from China.
DUDA is a type of diurethane that contains two methacrylate groups, which makes it an excellent reactive diluent for UV-curable resins. It is a clear, yellow liquid that has a low viscosity and can be easily mixed with other monomers and oligomers. Its unique chemical structure provides exceptional UV absorption and light stabilizing properties, making it an ideal ingredient in many formulations.
One of the main benefits of DUDA is its ability to protect against the harmful effects of UV radiation. It absorbs UV light in the range of 280-400 nm, which is the most damaging part of the spectrum. This helps to prevent degradation and discoloration of the substrate, as well as the formation of free radicals that can cause further damage.
DUDA is also an effective radical scavenger, which means it can neutralize free radicals and prevent them from causing oxidation and other chemical reactions. This makes it an excellent antioxidant that can extend the shelf life of products and improve their durability and performance.
DUDA is often used in combination with other UV absorbers and stabilizers to achieve the desired level of protection. One popular product that is similar to DUDA is BASF light stabilizer Tinuvin 360, which is a blend of UV absorbers that provides superior light stability and weathering resistance. Other equivalent or similar types of products include BASF Tinuvin 360, UV Absorber UV-360, Light Stabilizer UV-360, octyl triazole, oxytriazole, and various derivatives of 2,2-methylenebis(benzotriazole) and 1,3-dihydrobenzotriazole.
The use of DUDA is not limited to coatings and adhesives. It can also be used in a variety of other applications, such as fibers, films, and injection-molded parts. Its low volatility and high thermal stability make it a suitable ingredient for high-temperature processes, such as powder coatings and thermosetting resins.
In conclusion, diurethane dimethacrylate is a versatile UV absorber that offers exceptional protection against UV radiation and other environmental factors. Its unique properties make it an ideal ingredient in many formulations, and it can be used in a wide range of applications. INNO Specialty Chemicals is a reliable supplier of high-quality DUDA that meets the strictest standards of quality and safety.
