2 a) A coating formulation consists of an epoxy thermoset and the following additives: acetone; silica particles, slate powder; poly(propylene glycol); rubber particles. Briefly describe type and function of each additive in the formulation of the epoxy resin. b) Describe what happens during the curing process of a thermoset, if the curing temperature is equal to the glass transition temperature of the thermoset. c) What kind of structural modification would you consider in an epoxy resin thermoset to increase the following properties: i) ii) iii) iv) fire resistance; flexibility; UV resistance; glass transition temperature. d) Why do amino-formaldehyde thermosets have a better tracking resistance than phenol-formaldehyde thermosets
