Tie each reactor cook, test value and drum of resin to its recipe and its buyer.

A resin plant sells a set of numbers as much as a liquid: acid value, viscosity, solids content, colour, hydroxyl value and gel time. Two cooks of the same grade are never quite alike. The customer still expects every number on the certificate to be true for the drum on the truck.

This software follows the cook from the reactor to the drum. Raw material charges, temperature steps, in-process samples and final values are recorded against one batch. A buyer’s question about gel time or colour then opens a single record instead of three notebooks.

Operators charge the reactor with monomers, glycols, acids, oils or catalysts according to the recipe, then heat it in careful steps while the water of reaction is drawn off through the condenser. Samples are drawn during the cook for acid value and viscosity, and the cook continues until both reach target. The batch is cooled, thinned with solvent where needed, and passed through a bag filter into a holding vessel while the laboratory waits for the final numbers. Colour and solids are tested before the resin is run into drums or a bulk tank.

Customers include paint makers, laminators, adhesive makers and foundries, and every one of them buys a grade against a written specification that lists limits for the values the laboratory measures. Each expects a certificate with the lot. Rework is common. A batch that finishes high in viscosity may be thinned with solvent, blended with another lot of the same grade, or held back until the customer agrees to accept it. The record of what was added is what keeps the grade honest.
