By utilizing a pH indicator having known color change characteristics, an accurate determination of the pH of a binder surface, and hence the amount of cure of a polycarboxylic acid based binder on the fiberglass fibers, can be easily determined for polycarboxylic binder based fiberglass materials used in insulation and composite applications. Based on these results, the manufacturing line used to make these bindered materials may be adjusted to ensure adequate curing at maximum efficiency while minimizing operating costs and reducing waste.

En utilisant un indicateur de pH à caractéristiques connues de changement de couleurs, on peut déterminer avec précision le pH de la surface d'un liant, et par-là le niveau de durcissement d'un liant à base d'acide polycarboxylique liant les fibres de verre de matériaux liés utilisés pour l'isolation ou des applications composites. En fonction de ces résultats, la chaîne de fabrication de ces matériaux peut être ajustée pour garantir un durcissement adéquat avec le maximum d'efficacité tout en réduisant les coûts de fonctionnement et les déchets.
