Although butyl sealant accounts for less than 5% of the overall cost of insulating glass, due to the characteristics of the insulating glass sealing structure, the sealing effect of butyl rubber can reach 80%.
Because butyl sealant is used as the first sealant for insulating glass, its main function is to seal and maintain a very low water vapor transmission rate.
So in the selection of butyl sealant, what aspects need to be paid attention to, so that you can choose a better butyl sealant without stepping on the pit?
Today Peter is here to give you a brief introduction
When looking at butyl sealant, the first thing to check is whether the information is complete, such as product certification, company information, production date, shelf life, etc., and if more accurate verification is required. Manufacturers can be required to provide product testing reports.
Then observe the body of butyl rubber. Good butyl sealant is black and bright in color, smooth and free of particles, and has no bubbles.
In addition, the shelf life of general butyl sealant will be more than 2 years, and the butyl rubber with better quality can reach 3 years. If the shelf life of a butyl sealant is less than two years, either the quality of the product is not good, or it is stock.
Under the same quality of butyl sealant the larger the volume, the better the quality. Under the same volume, the more the glued area, the better the quality. However, inferior products may appear to be of high quality and volume, but the quality of the butyl rubber is large. The area of the glue will be much smaller.
