Chemique Adhesives, a leading UK manufacturer of high-performance industrial adhesives and adhesive application equipment has launched Solfre PressSmart, an advanced threecomponent (3C) polyurethane adhesive system designed to maximise efficiency, improve flexibility, and ensure consistent output in sandwich panel manufacturing.
Solfre PressSmart consists of two Part A components and a single Part B hardener. The two Part A components contain different catalyst levels – one fast-curing and one slow-curing, providing manufacturers with the ability to adjust processing times in real time and maintain consistent results regardless of ambient temperature.
By varying the blend ratio of the fastand slow-curing Part A components during application, manufacturers can precisely control open time, press time, and total cure time to match production requirements.
Automated application equipment precisely mixes the two Part A components at the required ratio, guaranteeing consistent performance for each panel. This provides a wide processing window, with open times ranging from 10 to 100 minutes and total cure times from 30 to 300 minutes, enabling reliable adhesive performance in both hot and cold production environments.
For even greater production efficiency, Solfre PressSmart allows ratios to be adjusted between adhesive coats. Increasing the proportion of the fast-curing Part A component in later coats shortens press times without affecting open time or handling characteristics.
