Arcfoil OV 130 Overprint and Spacer Varnish for Foil

A varnish applied over print on the foil web to protect the image through converting, die cutting and filling and to set the surface behaviour of the reel. Used as a spacer varnish, it keeps the wraps apart on the reel and prevents print pick-off on unwind.

1. Product description

A varnish applied over print on the foil web to protect the image through converting, die-cutting and filling, and to set the surface behaviour of the reel. It is formulated to control the coefficient of friction, measured to ASTM D1894, and to resist blocking when the coated web is wound warm and stored. Used as a spacer varnish, it keeps the wraps apart on the reel and prevents print pick-off on unwind.

2. Features

  • Protects the printed image through converting, die cutting and filling
  • Coefficient of friction set to an agreed target, measured to ASTM D1894
  • Resists blocking when the coated web is wound warm and stored
  • Acts as a spacer varnish to prevent print pick-off on unwind

3. Recommended uses

Overprint protection and winding control on printed aluminium foil, printed foil and paper laminate and lacquered foil, applied inline after printing or on a separate coating pass.

Substrates. Printed aluminium foil 20 to 50 micron; printed foil and paper laminate; lacquered foil.

AppearanceClear to slightly hazy liquidvisual
CarrierOrganic solvent blendformulation
Non-volatile content25 to 40 per cent by weightISO 3251

Blocking and pick-offNo blocking or print pick-off on unwind under the agreed winding and storage conditionscustomer or supplier protocol

Typical values, not a specification. Values for each batch are given on its Certificate of Analysis.

5. Application

ParameterGuidance
Application methodRoll coated or gravure applied on a web coating line, oven cured, inline after printing or on a separate pass
Substrate and surface preparationPrinted aluminium foil 20 to 50 micron, printed foil and paper laminate or lacquered foil; print fully dried before varnishing
DilutionSupplied ready for use; if reduction is needed, use only the thinner specified by Arctic for the grade and recheck supply viscosity and solids
Applied dry coat weight3 to 5 g/m2, checked gravimetrically across the full web width
CurePeak metal temperature 150 to 180 degrees Celsius; under-cure leaves retained solvent that shows as blocking on the reel
Specification inputsState the coefficient of friction target, winding temperature and storage conditions at enquiry; any digitally printed foil needs a press trial on the customer's own press

Process. Roll coated or gravure applied on a web coating line and oven cured, inline after printing or on a separate coating pass.

6. Storage and handling

Store in the original containers, kept closed, in a cool, dry, covered area out of direct sunlight and within the temperature range given on the label. Shelf life is stated on the label and on the Certificate of Analysis. Handle and use the product in line with its Safety Data Sheet.

7. Safety and regulatory information

Read the Safety Data Sheet before use. Safety Data Sheets and regulatory declarations are issued by our technical centre against the product and batch supplied, so they are sent on request rather than published. Request a Safety Data Sheet or declaration.
