3. Deep Cure for Pigmented and Thick Coatings

Effective in Opaque Systems

Sometimes you need coatings that cover well and look solid. Pigmented and thick coatings can block light. This makes it hard for some photoinitiators to work. Fotoinitiator 819 DW fixes this problem. It absorbs light at longer wavelengths. This lets it reach deep into the coating. You get a full cure, even if the coating is dark or has lots of color.

If you use this photoinitiator, you do not get sticky spots. There are no soft layers under the surface. The whole coating gets hard and smooth. This helps your products last longer and look nice. You can use it for plastics, textiles, and other materials. These need strong and deep curing.

Tip: Deep curing helps your coatings resist scratches and damage. You get a finish that stands up to daily use.

Reliable for Multiple Substrates

You want your coatings to work on many surfaces. Photoinitiator 819 DW gives you this choice. It works well on metal, paper, leather, and more. You can use it for packaging, car parts, or decorations.

Here is a table that shows how it works on different surfaces:

Photoinitiator 819 DW makes pigmented and thick coatings stronger. Your coatings do not turn yellow from UV light. They stay tough over time. This makes your products last longer and stay stable, even in hard conditions.

You can trust this photoinitiator for deep, even cures on many surfaces. Your coatings will look good and last longer, wherever you use them.

4. Broad Compatibility in Formulations

Works in Water-Based Coatings

You want a photoinitiator that works with many coatings. Fotoinitiator 819 DW gives you this choice. Older photoinitiators do not mix well with water-based coatings. They can make the coating look uneven. Sometimes, spots do not cure right. This can cause weak or bad areas in your finish.

Photoinitiator 819 DW mixes well in water-based coatings. It spreads out evenly and does not clump. You see fewer problems and get a smooth finish. Your coatings dry faster and cure better.

• Conventional photoinitiators: Do not work well with water-based coatings. This can cause uneven mixing and problems.
• New water-based photoinitiator: Mixes better, spreads out easily, and cures faster.
