Usage Guidelines

1. Formulation Recommendations

   • Mix IOTA-280 with vinyl-containing silicone oil/resin at a thiol-to-double-bond molar ratio of 1:1 to 1:2.

   • Add 5–10% of a UV photoinitiator (e.g., TPO, Irgacure series) based on the total system weight.

2. Curing Process

   • After coating the substrate or injecting into a mold, irradiate under a 200–400 nm UV lamp for 1–10 seconds.

   • Adjust irradiation time and intensity based on coating thickness and curing requirements.

3. Precautions

   • Store and operate in a light-protected environment to prevent pre-curing.

   • Ensure thorough mixing before use to maintain uniformity of the reaction system.
