What is the minimum surface temperature required for solvent cement?

The minimum surface temperature required for solvent cement to effectively bond materials is indeed 5°C (40°F). This temperature ensures that the solvent cement can properly evaporate and create the necessary chemical reaction for a strong adhesion.

When applying solvent cement, it is crucial that the surfaces are above this minimum threshold. Cooler temperatures can slow down or inhibit the evaporation process, leading to improper bonding and potentially weak joints. In addition, if the temperature is too low, the solvent may not spread evenly or penetrate the surfaces adequately, resulting in a failure to achieve the desired connection between the pipes or fittings.

While other temperature options provided may seem plausible, they either fall below the threshold needed for effective solvent cement application or do not ensure the appropriate conditions for a secure bond. Therefore, maintaining a minimum of 5°C is essential for optimal performance when using solvent cement in plumbing applications.
