A CAS number identifies a specific substance. Commercial products are often mixtures or proprietary grades, so always confirm details against the supplier’s SDS and TDS.
Reactive families (isocyanates, polyols, amines and epoxies) build the polymer network. Formulation families (acrylics, solvents, pigments and additives) shape how it is applied, how it looks and how long it lasts.
