Cashew nut shell liquid
NSA1921 resin should be used along with another methylene donor, such as HMT or HMMM, in the rubber compounding applications. In order to achieve an optimum reinforcement in rubber compounds, it is suggested that NSA1921 can be used at about 5~15 phr levels. at the same time, 7~10% HMT or HMMM should be added. In the rubber compound mixing process, to avoid pre-vulcanization and also to achieve good scorching property, NSA1921 resin should be added during the first stage of mixing. HMT or HMMM should be added together with sulfur and accelerators at the final mixing stage.
