MECOSTAT® 3/221

•  long term antistatic finishing for several years with reduction of the surface resistance as far as 1*106 Ω at standard climatic conditions
•  antistatic effect also at low humidity (< 15 % rH)
•  strong adhesion of the antistatic agent to the plastic surface resulting in high stability against physical effects such as friction etc.
•  the coating is temperature resistant resulting in unproblematic thermoforming without impairing the antistatic finishing
•  excellent wetting properties on plastic surfaces resulting in good antistatic finishing even under difficult thermoforming conditions
•  the slip properties of the plastic surfaces are improved considerably by the coating, therefore improving the stackability of thermoformed parts
•  no migration into the packed material, no accumulation during recycling
•  striationfree highly transparent coating
•  MECOSTAT3/221 is high yielding and therefore keeps down costs of antistatic finishing
•  unproblematic recycling of the coated plastics

MECOSTAT-3/221 is environment-friendly and easily biodegradable.

Antistatic finishing of

•  special packaging for electronic items and devices
•  thermoforming sheet (up to 800 µm)
•  other foils and sheets
•  molded, injection molded and hollow bodied parts
•  profiles

• the following processes are suitable for coating: immersion, felting, roller application, application by flexographic or gravure printing spray coating, rotor spraying coating (the
• appropriate processes are dependent on the particular application purpose) 
• coating quantity: depending on the application purpose 1.0 to 3.5 g per sqm (wet coating amount)
• the coated surface must be completely dry before further processing or winding the film (if required, drying with warm air)
• If MECOSTAT3/221 is applied on warm plastic surfaces, the surface temperature should not exceed 80 °C
• MECOSTAT3/221 is delivered as a ready for use solution
• machine parts which come into contact with MECOSTAT3/221 should be made of corrosion proof materials (not of copper, aluminum or alloys of them)
• a combination of MECOSTAT3/221 with antistatic agents is not recommended because of possible reactions
• depending on the particular application corona pretreatment is recommended (on polyolefines and polystyrene)
• due to the large number of applications and processing procedures we would like to point out that corresponding tests have to be performed by the customer to make sure that there will be no incompatibility with the raw materials, additives and the processing procedures
