A natural adhesive of low odour, it has a wide application in the book binding industry. Its special chemical additives give it a longer open time than normal, but nevertheless still retaining a good initial tack. It can be applied by brush for spine work or by machine (i.e. Balema, Swift or Nubal) for hand assembled case making, and is eminently suitable for conservation work.

This adhesive has additives to reduce cracking and to give very good non-warp characteristics to the case.

For those requiring an adhesive for use on automatic case making machinery we would recommend our Sheppy Jelly adhesive C1 Flex.

DIRECTIONS FOR USE:

Packed in 12.5 kilo corrugated cases with Polythene liners, this adhesive should be turned out of the box and cut into 1 - 2 kilo slabs, before being placed in the adhesive trough.
The adhesive should be heated to a temperature of 50°- 60° C (120°- 140° F) when it will liquefy and be ready for use. In no circumstances must the heat of the adhesive exceed 60° C (140° F) otherwise one risks the adhesive becoming degraded.
The adhesive may require dilution, dependent on the work in hand, or to replace loss of water from evaporation. In such cases, small quantities of warm water may be added.
In common with all natural adhesives, it is recommended to clean the adhesive troughs regularly to maintain the good quality and preserve the odour and colour of the adhesive.
This adhesive is completely non-foaming.

NB: Open time of this adhesive can be lengthened by increasing the operating temperature to 60° C and/or the addition of warm water.

Effect on the Environment
Being a natural colloid, this adhesive is water soluble and any paper/board bonded with it
is completely recyclable. It is also biodegradable in normal effluent processing plants and
will break down in the soil to become an organic plant nutrient.
