In order to prevent polymerization, 4-Hydroxybutyl Acrylate (4-HBA) must always be stored under air and never under inert gases. The presence of oxygen is required for the stabilizer to function effectively. In order to minimize the likelihood of overstorage, the storage procedure should strictly follow the “first-in-first-out” principle. For extended storage periods over 4 weeks, it is advisable to replenish the dissolved oxygen content. The storage temperature for 4-Hydroxybutyl Acrylate (4-HBA) should not exceed 25 °C. The preferred construction material for tanks and pipes is stainless steel. Carbon steel is also acceptable, although the formation of rust may be a problem with product quality (color). Iron(III)-ions are a weak polymerization initiator. If carbon steel is used, special procedures should be used to prepare the tank.
