Application
Most resins are suitable for use on both new and reclaimed sand ildeally at additions of 0.65 - 1.2%. Due to the range of nitrogen contants available, the resin can be chosen, which gives the most metallurgically and economically acceptable system.
Catalyst choice is important because it can significantly affect binder performance. Strip times are controlled by type, concentration and amount of catalyst used. Addition rates can vary between 25 - 75% based on resin weight, but optimum levels for both environment and performance are 25 - 50%. Strip times from 1 minute to more than 120 minutes are achievable by proper catalyst selection and application.
