Handling & Protection
Use enclosed low-splash transfer and adequate ventilation. Prevent enzyme mist and dried-residue dust; do not spray or use high-pressure cleaning. Wear suitable gloves, eye protection and work clothing, with respiratory protection where airborne enzyme cannot be adequately controlled.
What Is Coating Enzyme?
Coating enzyme is a liquid amylase preparation for converting native starch on site for paper surface sizing and coating. It lowers starch viscosity to the level the size press or coater needs, which can replace pre-modified starch.
The supply grade is a light brown liquid with activity above 100,000 U/mL; pH and density are listed in the specification table.
It is not regulated as dangerous goods. Enzyme activity depends on temperature, pH and contact time, so the dose is set by mill trials. Avoid inhaling enzyme mist, which can cause respiratory sensitization.
As a starch conversion enzyme supplier and exporter in China, ZXCHEM packs it in 20 kg or 200 kg drums or 1,100 kg IBCs.
