Mitigating Oxygen Inhibition in Light-Curable Materials
Oxygen inhibition is a very common problem for materials that cure by free-radical polymerization. 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.
