HOWARINE CALVERT INTERCOTE & SUPERFLEX

For production of a glued, self separating set of normal bond or bank paper

Many companies are unaware that it is possible to produce a self separating glued set with bond or bank paper, in a similar manner to that possible with carbonless (N.C.R) paper.

The process works by pre-treating the middles sheets before collation with a chemical agent called Inercote. When dry the sheets are collated together with the two untreated outer sheets (top sheet and bottom sheet), and the whole stack glued up with Superflex Adhesive. When dry the sets will fan apart without the requirement to knife apart by hand. If carbon paper with a selvedge forms part of the set, this should be treated with Speedcote. If a two part bond set is required, the Howrex System should be utilised.

Inercote, Superflex and Speedcote are available directly from GluesDirect.co.uk in either 5 litre or 3 litre containers.

Please see below for the guide on how to apply the Howarine Calvert Intercote & Superflex:

Fan-Apart 3 Parts to 8 Part Plain Paper Sets

•  Before collating treat all middle sheets of set with Inercote adhesive Agent. Sets with one-time carbon only treat selvage of OTC with Speedcote and not middle bond/bank sheets.

•  Stack sheets on bench or in Howapress. Place a thick strawboard along edge to be treated; clamps or heavy weights should not be used. (Skim trim OTC paper).

•  Using a flat side of a very soft 5-7cm brush, apply Inercote or Speedcote. Start at top and with light horizontal strokes brush from centre towards sides. Then brush over once more in same manner {making sure left and right edges are well treated}, ensuring penetration of 2mm.

•  Check Inercote or Speedcote penetrates 2mm by lifting a corner of pile shortly after brushing. To find Inercote treated edge of dry sheets of paper, moisten edge. If moisture penetrates, the sheet edge has been treated. Speedcote is solvent based and may discolour tinted sheets.

•  Superflex adhesive is applied with a separate brush after collating into sets; Inercote-treated inner sheets with untreated outer sheets. Jog well, preferably using a flat ‘table top’ Howajogger.

•  Stack sheets on bench or in Howapress. If pile is ‘spongy’ apply enough pressure to reduce ‘sponginess’. Apply Superflex adhesive, using Superflex brush. Brush must be fully saturated, apply 2 coats wet on wet.

•  When dry, fan sets apart by gentle sideways movement along gluing edge. Inercote Ink additive also available to print on middle sheets and on web. If mixing bond and ‘NCR-type’ sheets, test 550mm pile of sets before collating job.
