Winter Construction Guidelines and Storage Methods for Silicone Adhesive

Release time:

Jan 07,2024

With the arrival of cold air, many regions switch to winter mode in one second. The cold weather affects the performance and storage method of silicone adhesive. So, how can we better utilize the effectiveness of silicone adhesive in low temperature environments?
Winter construction requires attention to methods
The curing speed of two-component silicone sealant is affected by temperature. The lower the temperature, the slower the curing process. Moreover, when the temperature is too low, there may be imperceptible fog or frost on the surface of the substrate, which affects the bonding performance of silicone sealant. To address the winter construction difficulties, the following measures can be taken:
1. Grasp the glue application time
It is recommended to carry out construction around noon. Due to the influence of moisture and temperature in the air, the surface temperature of the substrate is low in the morning and evening, which will be accompanied by varying degrees of shrinkage. After gluing, it is easy to cause problems such as bulging or difficult curing, which will affect the normal sealing effect.

2. Pay attention to the temperature of the construction environment
Under normal circumstances, it is necessary to increase the temperature of the construction site in an environment with a temperature below 5 ℃. It is recommended to conduct a small area of adhesive testing before use to confirm good bonding performance and no problems with curing before proceeding with large-scale construction. Of course, before construction, it is necessary to pay attention to the temperature range requirements indicated by the silicone adhesive manufacturer, strictly follow the requirements, and ensure construction quality.

Winter storage requires attention to strategy
While construction may be hindered, attention should also be paid to the storage of silicone adhesive in winter, otherwise it may cause deterioration or reduced performance of silicone adhesive. To address storage issues, the following measures can be taken:
1. Unopened adhesive
Unopened silicone sealant should be stored indoors in a dry and cool environment as much as possible, and the temperature should not be lower than the storage temperature indicated by the manufacturer. If the situation does not permit, it can only be placed outdoors. Protective measures should be taken, and the temperature of the sealant can be avoided from being too low by covering it with canvas or other methods.

2. Opened adhesive
Like two-component silicone sealant, component B is mainly composed of curing agent. If the part is opened for use, the remaining part will solidify once it contacts the air. After the covering film originally placed on the surface is cleaned, it can be covered in the form of clinging to the colloidal surface. Then, use the pressed foam packed in the barrel to isolate the air, and store it in a dry and cool indoor environment to prevent deterioration.

The restrictions on construction in winter are relatively large, but as long as operated properly, it will not cause damage to the performance of silicone adhesive. Details cannot be careless, so in order to ensure the quality of the project, everyone must store and construct in the correct way!
