Perfect Book Binding Glue

Planatol Planamelt R 


Perfect-binding of catalogues, brochures, telephone directories, magazines etc. on common perfect-binding systems at high machine speed. 

Planamelt R can also be used in two-shot processes as primer or as top coat depending on application temperature. 

Pasting and casing-in of thread-stitched book spines. 

Plasticizer-free hot melt adhesive for book spines with medium clamping effect and excellent adhesion to the sheet edges. 

The new polymer basis of Planamelt R offers various advantages against a common EVA hot melt glue, like better oxidation stability, better adhesion to the paper edges and better durability of the books, improved oil and heat resistance and reduced odour. By reduced density consumption is reduced by approximately 6% compared to conventional EVA-based spine glues.

For use with Thermal PVA Glue & Planamelt Glue

Application temperature (temperature taken at the roller):

One shot 130 °C – 180 °C

One shot, pasting of thread-stitched book spines 130 °C – 150 °C

Two shot as primer 160 °C – 180 °C

Two shot as top coat 130 °C – 160 °C

Inside premelter 10 – 40 °C lower

Heating for substantial periods as well as repeated heating will lead to a gradual darkening of the product, if heated for too long a period or at extremely high temperatures, the adhesive will finally be rendered useless. This is why the amount of adhesive to be processed should be in line with the user’s daily requirements.

Ideal conditions that guarantee a maximum durability (page pull values) are as follows:

Notch depth 0.5 – 1.0 mm

Distance of notches 4.0 – 7.0 mm

Dust-free book spine

Smooth coating width 0.5 – 1.0 mm

Prior treatment of book spines and the application quantity need to be adapted to the papers types used. Papers with long fibres require a smaller grooving depth, thin papers like, for example, rotogravure papers require repeated and deep grooving. If particularly heavy coated papers are involved, prior tests are essential.


Note Even if the prescribed working temperature is adhered to, hot melt adhesives release fumes which may be felt as molesting. Should the prescribed processing temperature be considerably exceeded for substantial time, there may also be the danger of development of harmful decomposition products. This is why the product’s user is held to take care for prophylactic measures like installing adequate suction devices and cleaning both the melting tank and the application unit at regular intervals. 

Cool but frost-protected, in its tightly closed original container. The adhesive should be finished within a period of six months.

Note The technical data and suggestions for processing and application range in the data sheet are based on our laboratory tests and experience and is therefore not binding .It can in this respect be given no warranty or guarantee , unless this has been explicitly agreed in writing 

by both parties. A self-test or a test of adhesives for suitability for the intended purpose of use by the user is imperative esp. Under the influence of production conditions.
