轮胎自补液在轮胎内部胎面区域形成一层薄膜，使产品封住胎面区域的刺孔。当轮胎被刺穿后，逼出的空气会带动自补液到刺孔处。自补液液体的一部分会渗出，而纤维和粘合剂会交织形成一个富有弹性的栓头。这使得这种产品能对任何产生的刺孔进行及时迅速的封堵。
因此当轮胎漏气时，不需要浪费时间去补胎。这种自我修复的自补液能防止轮胎漏气长达两年。 自补液在轮胎转动时，离心力会迫使自补液在胎面区域形成一层保护层，修复可能产生及现有的刺孔。

How does the real tire sealant work?
The tire sealant coats the inside of the tire within the tread area, allowing the product to seal tread area punctures. When the tire is punctured, the escaping air carries the sealant to the puncture. The liquid portion of the sealant escapes and the fibers and binders build-up and intertwine to form a flexible plug. This will allow the product to instantly seal any puncture that may occur.
Don’t waste time repairing a flat tire. The self-healing sealants prevent flats for up to two years. As the sealant treated tire rotates, centrifugal force pushes the sealant to the tread area creating a layer of protection, repairing punctures as they occur and treating existing punctures.
