Detail 

  Transport or Storage:    Stored in a ventilated, cool and dry place, away from fire. Transport should be handled with care to prevent damage to packaging.

  Usage:    Fiber can be divided into basic and non-fiber products that we tend to non-fiber, more extensive use, can be used in coatings, adhesives (to prevent the paint from the skin, loss), textile, construction, wood processing, paper making, printing . Play a major role in bonding.

  Features:    And CMC, have a customer needs the product price, must first ask him what is specific to the viscosity and specific purposes.
