Technical Information

Polybond inks are a range of single pack screen inks formulated for printing treated polyethylene and polypropylene bottles. etc.

These inks are normally used as supplied, thinned 10-20% with one of the recommended thinners. For certain applications, where product resistance of the ink needs to be developed soon after printing, Polybond Catalyst is available.

Pre-treatment For satisfactory adhesion to be maintained it is essential that containers are pre-treated, preferably immediately prior to the printing operation. Propane or Butane/Air flame pre-treatments are recommended. Because of variations in polyethylene container mouldings, a test should be carried out on each batch of containers prior to the production run.
Printing All types of stencil materials are suitable except Stenplex Amber or lacquer adhering films. Meshes 90-140T screens. A coverage of 23-43 sq m/kg can be expected with a 110T mesh.
Catalysed Inks When it is necessary to use the catalyst, the following mixing ratios should be used, prior to thinning:
Polybond inks 95 parts by weight
Polybond Catalyst 5 parts by weight
This mixture will give a pot life of approximately 24 hours. It is recommended that only sufficient is mixed for each days printing to avoid thickening.
Thinners All types of stencil materials are suitable except Stenplex Amber or lacquer adhering films. Meshes 90-140T screens. A coverage of 23-43 sq m/kg can be expected with a 110T mesh.
