When producing the insulated glass, what kind of sealant should be used for the second seal?

Insulating glass is a product that evenly separates two or more pieces of glass at a certain distance, and the periphery is bonded and sealed, so that a dry gas space is formed between the glass layers. According to the thickness of the gas layer required by the design, a spacer frame containing a desiccant is embedded between the two pieces of glass, and then two seals are performed on the periphery of the glass...

What are the double seals of insulating glass? What is the role of each?

The insulated glass first sealant uses butyl rubber, which has an extremely low water vapor transmission rate; the insulated glass second sealant mainly includes polysulfide glue and silicone glue. Insulating glass is always faced with external water vapor penetration and temperature changes during its service life, so it is required that the sealant must first be able to prevent external water vapor from entering the air layer of the insulating glass...

When the ambient temperature of silicone sealant is low in winter, the viscosity increases, and the sealant is not applied smoothly.

When the ambient temperature of silicone sealant is low in winter, the viscosity increases, and the sealant is not applied smoothly.

Insulating glass using silicone sealant is composed of chemical raw materials such as silicone rubber, silicone oil, and calcium carbonate. Taking winter in the northern hemisphere as an example, when the temperature drops in the winter in the northern hemisphere, silicone rubber, and silicone oil become thicker, less fluid, and more viscous. This thickening and sticky situation is normal and does not affect product quality.
