Bonding properties of insulating glass sealant mixed with oil

Using mineral oil as plasticizer will have an adverse effect on the bonding properties of insulating glass sealant. However, under the conditions of thermal aging and water ultraviolet aging, the adhesive properties of the sealant with oil will be greatly reduced.

Thermal aging properties of insulating glass sealant mixed with oil

Due to the low boiling point and high volatility of mineral oil, the insulating glass sealant with oil has a large thermal weight loss, which exceeds the upper limit of 10% specified in the standard at 90 ℃. The effect of mineral oil on the heat resistance of insulating glass sealant can be further studied by thermogravimetric analysis.

Durability of insulating glass sealant mixed with oil

Due to the great heat loss of oil-doped insulating glass sealant, the surface cracking phenomenon of oil-doped insulating glass sealant appears after accelerated aging test, which indicates that its durability will be greatly reduced, and then has a serious impact on the service life of insulating glass.
