Adhesive & Coating Cure Chemistry

This simulator visualizes two real adhesive-curing mechanisms side by side. On the left, epoxy resin monomers and a polyamine hardener collide and react: each N–H bond opens an epoxide ring, wiring the mixture into a single crosslinked thermoset network whose stiffness rises as curing completes, at a rate you control with temperature. On the right, cyanoacrylate ("superglue") monomers undergo anionic chain polymerization — a trace of surface moisture initiates a carbanion that propagates almost instantly along a growing chain, the mechanism behind superglue's near-instant set. Live gauges track conversion, crosslink density, and the resulting stiffness/elasticity trade-off as the network forms.
