MECOSTAT® 3/724

• long term antifog, antiblock and antistatic finishing for several years 
• surface resistance as far as 108 Ω at standard climatic conditions
• strong adhesion of the coating 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 antifog, antiblock or antistatic finish
• the slip properties of the plastic surfaces are improved by the coating
• o nmigration into the liquid filled, no accumulation during recycling
• striation-free highly transparent coating
• usable in the packing industry for foodstuffs according to EC-Directives
• MECOSTAT-3/724 is high yielding and therefore keeps down costs of antifog, antiblock and antistatic finish
• problem-free recycling of coated plastics

Antifogging, antistatic and antiblocking finishing of

• transparent thermoforming sheets
• transparent films for food packaging
• transparent films for packaging of farm products
• transparent, technical films

• Antifogging performance hinges on two chemical capabilities: sheeting and hydrophilicity, (the compatibility of the molecules with water).
• Water ordinarily condenses on a surface as tiny droplets, which refract light in such a way that you cannot easily see through the surface. If the surface is treated with an antifogging agent, you get a vastly different picture.
• The antifogging agent molecules are hydrophiles, so they dissolve in the water droplets. And as they do, they lower the surface tension of the droplets. Droplets spread on the surface and form a continuous film. This film refracts light the same way as a dry surface with the result of a clear visibility.

• the following processes are suitable for coating: immersion bath, felting, roller application, application by flexographic or gravure printing (the appropriate processes are dependent
• on the application purpose). If MECOSTAT-3/724 is applied on warm plastic surfaces, the surface temperature should not exceed 50 °C
• coating quantity: 1 to 3 g per sqm (wet coating amount)
• MECOSTAT-3/724 contains isopropyl alcohol, use explosion-proof installations
• the coated surface must be completely dry before further processing or rolling up the sheet (if required, drying with warm air)
• MECOSTAT-3/724 is supplied as a ready for use solution
• machine parts which come into contact with MECOSTAT-3/724 should be made of corrosion proof materials but not from copper, aluminum and their alloys
• a combination of MECOSTAT-3/724 with antistatic additives 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
