The Risk of Gelling in Resin Polymerization
Alkyd resin manufacturing relies on esterification cooking at temperatures up to 240—C. Reaction progress is tracked by Acid Value (AV) and viscosity. If AV drops too low, the batch polymerizes completely and gelation occurs, ruining the reactor. Manual sampling is slow and dangerous.
High-Temperature Process Probes
USTECH high-temperature sapphire immersion probes are installed directly inside the resin reactor wall. The probes withstand continuous exposure to hot, viscous mixtures. Live AV and viscosity predictions are updated continuously, guiding the exact dilution endpoint.
