Cashew Nut Shell Resin is biodegradable. But it has short shelf life as it starts decomposing. What is the approximate shelf life of Cashew Nut Shell Resin Composite and how can we improve it?

You can make the CNSL work for you if you add tolouene to it. It prevents the CNSL from polymerizing or degrading up to 110 celsius. Normaly , CNSL polymerizes at 120 to 200 Celsius depending upon whether it is formaldehyde cured or acid cured. Toluene, which evaporates at 110 celsius allows polymerization beyond 110 celsius. At room temperature it gives a long shelf life to cnsl by preventing it from self polymerization. Thanks
