Production process introduction

  • The product is kept in a complete package and stored in a dry indoor warehouse at room temperature. and should not be exposed to the direct sunliaht it is recommended to use it within 2years, and it should be used immediately after opening the package.
  • lf the moisture in the product is not completely removed before processing,it will cause hydrolysis and reduce its molecular weight and reduce the performance of the final product. Therefore it is recommended that the product be dried at 165+10℃ for 4-6 hours before processing is fully dewatered.
