With production resuming at the end of August and the arrival of autumn, manufacturing plants face an invisible threat: temperature fluctuations and humidity in the production halls.
The shift from lingering summer heat to the first drops in temperature is not merely an environmental factor, but a variable that directly affects the performance of standard polyurethane resins and adhesives.
What happens to the resin when the weather changes?
When environmental conditions fluctuate, uncalibrated chemical systems react immediately:
- Fluctuations in viscosity: heat makes the resin too runny, causing drips; cold thickens it, making it difficult to dose in mixers.
- Unpredictable setting times: high temperatures reduce the pot life (risking nozzle blockages), whilst cold temperatures prolong polymerisation, slowing down the entire production line.
- Humidity and defects: moisture in the air reacts with isocyanate to generate carbon dioxide, causing micro-bubbles, cracks and structural failures.
The solution: adapt the chemistry, not the plant
Constantly adjusting machinery settings or air-conditioning production halls entails enormous energy costs. Texachem’s approach is the opposite: tailoring the chemical formula to the customer’s actual conditions.
In our laboratories, we formulate polyurethane systems with:
- Stable workability windows, to maintain consistent setting times in both hot and cold conditions.
- Controlled viscosity, to ensure consistent dosing in every season.
- Additives to eliminate unwanted reactions and prevent micro-bubbles or defects.
