Comparative resin deformulation clarified the composition and synthesis direction needed to unblock a solvent-based phenolic fireproof coating program.
Project context
A coating manufacturer was developing a solvent-based phenolic fireproof coating. Fillers and additives remained stable in internal trials, but final performance remained below target and resin selection delayed development for almost six months.
Two reference resin samples were available, but the customer needed to understand their composition, likely monomer logic and raw-material direction before rebuilding a suitable resin system.
Analytical approach
Compare a light-yellow phenolic resin and a milky urea-formaldehyde reference sample.
FindingThe comparison highlighted material differences relevant to resin selection and compatibility in the solvent-based coating system.
Investigate key components, likely monomer sources and formulation-level differences.
FindingThe analysis clarified the main composition features and possible raw-material choices behind the reference resins.
Relate the analytical evidence to hardness, flexibility, weathering and filler compatibility needs.
FindingThe results provided a more focused synthesis direction instead of further blind trials with commercially named resin categories.
