Epoxy resin cures through an exothermic polymerisation reaction, allowing brief fluidity for wave manipulation before hardening into a durable, translucent medium that captures light like genuine seawater, as detailed in polymer chemistry res

emilia angelillo on Instagram: "Nylon is a polyamide and it is produced through a condensation polymerisation reaction. Polyamides are typically formed by reacting a dicarboxylic acid with a diamine monomer. A cyclohexane solution of decanedioyl dichloride is poured on a aqueous solution of 1,6 diaminohexane, carefully and slowly so that mixing is minimised. A greyish film of the polymer nylon will form at the interface and it can be carefully picked up with a pair of tweezers and lifted slowly
