Cured resin or duromers
WebCure for thermosetting resins is defined as a process for changing the properties of a resin via chemical reaction with evolution of heat & any volatiles, increase in viscosity, … WebSo live resin is whole plant fresh frozen. This preserves a lot of the terpenes so you get the full taste which I absolutely love a lot of the time. Some amazing flavoured dabs occur as a result. Cured resin you lose some terps but you get more of a full spectrum product which means that you get more of a ‘stone’ high.
