Butyl Sealant: Concept, Characteristics, and Primary Applications

Butyl sealant is a single-component, environmentally friendly, non-curing, self-adhesive sealant processed from butyl rubber through special techniques. It is designed specifically for the characteristics of industries like blade manufacturing and can be widely used in automotive, construction, industrial, and other applications.


Its main advantages include:


Single-component, easy to use, with good stability across a temperature range of -40°C to 120°C.


Non-curing and non-corrosive to materials such as metals, coated glass, concrete, marble, and granite, making it widely applicable.


Capable of withstanding certain deformation, offering plasticity.


Resistant to UV light, ozone, water, and chemical corrosion.


Solvent-free, safe, and environmentally friendly.


Easy to apply and economical in material usage.


Long service life of over 20 years and capable of extended storage.


Butyl sealant, using isobutylene polymers as its main material, is one of the four most widely consumed sealants in the world. It boasts excellent weatherability, heat resistance, acid and alkali resistance, as well as superior air tightness and electrical insulation properties.
