Mitigating Oxygen Inhibition in Light-Curable Materials
|A very common problem for materials that cure by free-radical polymerization is mitigating oxygen inhibition. Early chain termination can occur when radical molecules react with the oxygen in the air, resulting in an incomplete cure on any surfaces exposed to air. Oxygen-inhibited surfaces are normally tacky or sticky. Luckily, there are several physical and chemical ways to reduce oxygen inhibition when working with or formulating light-curable materials.
Learn the 8 ways to reduce oxygen inhibition in the infographic below and explore some advantages and disadvantages of each.
