- Typical Properties of the Coating with MECOSTAT-3/145
- long term antistatic finishing for several years with reduction of the surface resistance as far as 108 Ω at standard climatic conditions
- antistatic effect also at low humidity (< 25%)
- strong adhesion of the antistatic agent to the plastic surface resulting in high stability against physical effects such as friction etc.
- temperature resistant coating results in unproblematic thermoforming without impairing the antistatic finshing
- excellent wetting properties on plastic surfaces resulting in good antistatic finishing even under difficult thermoforming conditions
- the slip properties of the plastic surfaces are considerably improved by the coating, and therefore improves the stackability of the thermoformed parts
- MECOSTAT3/145 replaces the additives used until now
- no migration into the liquid filled, no accumulation during recycling
- striationfree highly transparent coating
- MECOSTAT3/145 is highly productive and therefore keeps down costs of antistatic finishing
- usable in the packing industry for foodstuffs according to ECDirectives
- problemfree recycling of coated plastics
Applications & Uses

- Plastics & Elastomers End Uses
- Plastics & Elastomers Processing Methods
- Areas of Application
Antistatic finishing of
- films, sheets, profiles and thermoformed parts of all types (films up to 800 µm)
- packing for food
- technical sheets
- molded, injection molded and hollow bodied parts
- mono and multifilaments, threads and fabrics of all kinds
- Processing Directions
- the following processes are suitable for coating: immersion, felt application, roll coating and application by flexographic or gravure printing, spray coating, rotor spraying coating (the
- appropriate procedures depend on the purpose of application). If MECOSTAT3/145 is applied on warm plastic surfaces, the surface temperature should not exceed 80 °C
- coating quantity: according to the purpose of application between 1 and 4 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)
- MECOSTAT3/145 is supplied as a ready for use solution
- machine parts which come into contact with MECOSTAT3/145 should be made of corrosion proof materials but not from copper, aluminum and their alloys
- a combination of MECOSTAT3/145 with antistatic additives is not recommended because of possible reactions
- depending on the application, a Corona pretreatment is recommended (e.g. 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
