The biggest technical highlight is the vacuum exhaust valve design, which automatically discharges excess air after each extrusion, maintaining a negative pressure state in the bottle to prevent the adhesive from contacting oxygen and curing prematurely. The BPA-free HDPE material is non-toxic and has good chemical corrosion resistance, will not react with silicone adhesive. The translucent white body allows users to clearly observe the remaining amount of adhesive, and the wide bottle mouth design is convenient for refilling adhesive. It also meets FDA and CE safety certifications, ensuring that the adhesive will not be contaminated during storage.
