If you're a manufacturer or supplier of UV-curable coatings, inks, and adhesives, you know that photoinitiators are an essential component of these formulations. Without a photoinitiator, UV light won't trigger the curing process that turns liquid coatings and inks into solid films and prints. That's why choosing the right photoinitiator for your application is critical for its performance, cost-effectiveness, and regulatory compliance.
One of the most popular photoinitiators used in the industry is 2-Isopropylthioxanthone, also known as ITX. This compound belongs to the thioxanthone family of photoinitiators, which are efficient, versatile, and compatible with a wide range of monomers and oligomers. ITX has a high absorption in the UV-A range (320-400 nm) and a long-lasting reactivity, making it suitable for both high-speed and low-energy curing systems.
Ningbo Inno Pharmchem Co., Ltd., a leading manufacturer and supplier of specialty chemicals, offers a premium grade of ITX photoinitiator under the brand name PI-ITX. This product is synthesized in the company's state-of-the-art factory using advanced technologies and quality control measures to ensure its purity, stability, and performance.
But what makes PI-ITX stand out from other ITX products on the market? Let's take a closer look at its features and benefits:
1. High purity and low impurities
PI-ITX has a purity of ≥ 99%, which means that it contains less than 1% of impurities that could affect its reactivity, color, or odor. Some of the impurities found in other ITX products include 2-ethylhexyl-4-dimethylaminobenzoate (EDMAB), a known allergen and sensitizer, and benzophenone-type photoinitiators, which can cause yellowing and cracking in some formulations. PI-ITX is free from these impurities, making it a safer and more reliable choice for your products.
2. Excellent solubility and compatibility
PI-ITX is soluble in a wide range of monomers and oligomers commonly used in UV-curable coatings, inks, and adhesives. It can also be used in combination with other photoinitiators to achieve specific curing profiles or to reduce the overall cost of the formulation. PI-ITX has a low viscosity and a low volatility, which means that it won't affect the rheology or the VOC content of your product.
3. Fast and complete curing
PI-ITX has a high reactivity and a long-lasting activity, which means that it can initiate the curing process even at low concentrations and low UV doses. It can also cure thick layers or opaque substrates that might hinder the penetration of UV light. PI-ITX is suitable for both LED and mercury vapor lamps, and it can cure in air or under nitrogen atmosphere. It can also cure at room temperature or at elevated temperatures, depending on the requirements of your application.
4. Regulatory compliance
PI-ITX is compliant with the regulations of major chemical agencies and organizations, such as REACH, RoHS, FDA, and BfR. It doesn't contain any substances that are restricted or prohibited by these authorities, such as heavy metals, phthalates, or formaldehyde. PI-ITX is also listed in the inventory of existing chemical substances in China, Europe, and the United States, which means that it has passed the required registration and notification procedures.
5. Technical support and customization
Ningbo Inno Pharmchem Co., Ltd. provides technical support and customization services to its customers who need assistance in selecting the right photoinitiator for their specific applications. The company has a team of experienced chemists and engineers who can analyze your formulation, suggest the optimal dosage and curing conditions, and perform compatibility tests with your substrates and pigments. The company can also produce PI-ITX according to your specific requirements, such as particle size, color, or packaging.
In conclusion, PI-ITX from Ningbo Inno Pharmchem Co., Ltd. is a high-quality and cost-effective photoinitiator for UV-curable coatings, inks, and adhesives. Its high purity, excellent solubility, fast and complete curing, regulatory compliance, and technical support make it a feasible choice for manufacturers and suppliers who want to enhance the performance and competitiveness of their products.
