NITTO EPTSEALER 685Cseries

EPT-Sealer 685Cseries is a soft-closed cell EPDM foam with excellent sealing properties. The closed cell structure gives excellent water- and air-tightness, even under severe conditions, with low compression load. Furthermore it combines excellent heat insulation and soundproofing properties with a good cushioning effect.

This unique foam can be laminated with Nitto’s advanced adhesive technology to seal (complex) gaps against water, wind, dust, noise and heat.

Applications

- The performance of Nitto EPT-Sealer on specific substrate must be assured by the user before implementation.

- During storage and transport, do not over stack the product, as this may cause deformation.

-EPT-Sealer should be applied to clean and dry surface. Remove excess oil, moisture and dirt from the substrate surface to which the sheet is applied.

- In order to avoid entrapped air-bubbles, tension and shear, the customer should determine appropriate application conditions.

- The best application conditions are obtained at a temperature between 15 °C and 40 °C.

- Appropriate compression is needed to have sealing performance.

- In case of use of primer, check beforehand the impact of the primer to the performance of the EPTSealer. Wrong use of primer can lead to loss of adhesion.

- Please consult Nitto Europe for any robotic application regarding more specific precautions.- Thickness as referred in orders, article description and on the packaging is related to the foam and is excluding tape and release liner thickness.
