Features & Benefits
- Materials Features
- Areas of Application
Antiblocking / Antistatic / Antifog finishing of
- films, sheets, profiles and thermoformed parts of all types (films 500 up to 2000 µm)
- packing films
- molded, injection molded and hollow bodied parts
- foils for transparent packaging
- Typical Properties of the Coating
- long term antistatic finishing for several years with reduction of the surface resistance as far as 4*108 Ω at standard climatic conditions
- antistatic effect also at very low humidity (< 30%)
- strong adhesion of the coatingt 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 antiblock or antistatic finish
- excellent wetting properties on plastic surfaces resulting in excellent surface 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
- the blocking tendency of PET sheet is neutralized to a large extent
- MECOSTAT-3/2382 replaces additives used to date resulting in no migration in to the packed material, no accumulation during recycling
- reduced costs
- striation-free highly transparent coating
- usable in the packing industry for foodstuffs according to EC/FDA-Directives
- MECOSTAT-3/2382 is high yielding and therefore keeps down costs of antistatic finishing
- unproblematic recycling of the coated plastics
Applications & Uses

- Compatible Polymers & Resins
- Plastics & Elastomers End Uses
- Plastics & Elastomers Processing Methods
- Processing Directions
- 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 depend on the application purpose)
- typical coating amount: 1.5 to 5 g per sqm (wet coating amount)
- If MECOSTAT-3/2382 is applied on warm plastic surfaces, the surface temperature should not exceed 80 °C
- the coated surface must be completely dry before further processing or winding the sheet (if required, drying with warm air)
- depending on the application, a corona pretreatment is recommended (e.g. polyolefines and polystyrene)
- MECOSTAT-3/2382 coating agent is supplied as ready for use solution
- machine parts which come into contact with MECOSTAT-3/2382 should be made of corrosion proof materials but not from copper, aluminum and their alloys
- a combination of MECOSTAT-3/2382 with antistatic / antiblocking agents (e.g. silicon derivates) is not recommended because of possible reactions
- 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
