Permethrin Technical FAQ
What is the shelf life of Permethrin Technical?
When stored properly in its original packaging, away from direct sunlight and at temperatures below 30°C, Permethrin Technical maintains its effectiveness for at least 2 years from the date of manufacture. The product should be kept in a well-ventilated, dry place and protected from extreme temperature fluctuations.
How should Permethrin Technical be handled safely?
Always wear appropriate personal protective equipment (PPE) including chemical-resistant gloves, protective clothing, and eye protection when handling Permethrin Technical. Work in well-ventilated areas and avoid creating dust or vapors. In case of skin contact, wash immediately with plenty of soap and water. For eye contact, rinse cautiously with water for several minutes.

Permethrin Technical FAQ
What is the difference between cis and trans isomers in Permethrin Technical?
Permethrin Technical contains both cis and trans isomers, typically in a ratio of about 40:60. The cis isomer generally shows higher insecticidal activity but lower mammalian toxicity compared to the trans isomer. The specific isomer ratio can be adjusted during manufacturing to optimize performance for particular applications.
Is Permethrin Technical compatible with other agrochemicals?
Permethrin Technical shows good compatibility with many other insecticides and fungicides in tank mixes, but compatibility should always be tested before large-scale mixing. It should not be mixed with alkaline materials (pH >8) as this accelerates hydrolysis. Common compatible products include certain organophosphates and other pyrethroids.
Quality Control
Our Permethrin Technical undergoes rigorous quality testing, including:
