This sealant is made with the latest latex-enrichment technology, it has higher concentration of latex, which is the effective sealing agent, thus sealing punctures faster than common sealant. choice micro-fiber is added, on the one hand to enhance sealing performance, one the other hand to ensure better injectability through the valve stem, the fiber size strikes a perfect balance between sealability and injectability. as high-concentration latex is used, which means lower percentage of water in sealant, lower-temperature anti-freeze performance is achieved with more anti-freezing agent while still maintaining a high concentration of latex, thus high sealing performance, it works from-25℃to +70℃ . due to higher percentage of anti-freezing agent, our sealant stays liquid longer, up to 5-9months once injected into tires. furthermore, sophisticated ammonia removal technology is applied to make our sealant virtually ammonia-free and harmless to tires and rims.
