Butyl Sealant Used For Insulating Glass First Seal Insulating Glass
Processing
Why use hot melt butyl sealant for insulating glass?
Hollow glass (trough aluminum type) must adopt double sealing mode
to ensure its sealing and durability. That is, the first sealing
using hot melt butyl sealant, mainly plays a sealing role; The
second seal is completed by elastic sealant, which plays an
auxiliary sealing and keeps the structure of insulating glass
stable. The two complement each other and are indispensable.
Composition and function of butyl adhesive
Composition: Butyl sealant is mainly polyisobutene, butyl rubber as
the main material, reinforcing agent, tackifying agent, heat
stabilizer, softener, filling agent as ingredients.
Function:
Prevent water vapor from entering the hollow glass cavity
Fix the glass on both sides of the aluminum strip of the insulating
glass
Enough stability to continue to work
Performance of butyl adhesive and comparison of competing products
Water vapor transmittance
Refers to the ability of water vapor to pass through a material,
and the weight of water vapor through the material at a certain
temperature and humidity at a certain time.
Shear strength
Shear strength refers to the ability of the material to bear shear
force, refers to the external force perpendicular to the axis of
the material, and the strength limit of the shear action on the
material.
Confucianism degeneration resistance
Creep resistance refers to the phenomenon that the deformation
degree of a material increases with time under dead load (constant
external load). Creep reflects the rheological properties of a
material under load
Thermogravimetric efficiency
Thermogravimetry is to measure the change of weight with the
increase of temperature by heating the substance and making it
volatilize and decompose gradually
Overall appearance, actual performance of glue
In the process of use, it is shown to be black and glossy, and
there should be no residual black stains on the hand contact and
kneading hands.
