CrossCoat™ - Non-Contact Metered Slot Die Applicator
The CrossCoat™ is a non-contact, metered slot die applicator that produces a precise flow of adhesive for coating applications that require streak-free results.
Overview
ITW Dynatec’s CrossCoat™ applies the molten adhesive full-surface as a film and continuous to a substrate. The surface attraction of the adhesive enables it to be stretched as it is applied to the substrate, producing highly accurate and repeatable results. Cross-web accuracies to ±3% can be achieved with a minimum application coat weight of 1gsm at web speeds of 1,000 m/minute or more.
The CrossCoat Applicator can be used with a slot nozzle either with fixed coating width or with manually by hand wheels adjustable coating width.

Features
- Cross-web distribution accuracies to ±3%.
- Ideal for heat sensitive materials.
- Coat weights as low as 1gsm.
- Coat weight and width changes during production.
- Consistent coating on irregular surfaces.
- Streak-free finish.
- Non-contact application encapsulates surface contaminants instead of trapping them between the die lip and substrate, producing consistent coating performance while minimizing waste.
The Dynatec Difference
- No Heat Memory – Heat sensitive materials such as thin PP and PE film do not come into contact with the die lip, eliminating damage to the film.
- Conformity to Irregular Surfaces – Establishing an adhesive film enables 100% coating of fabrics, textured foils, technical textiles and other non-flat surfaces.
- Streak-Free Coating – Smooth and clear fluid coating that encapsulates substrate contaminants instead of producing dry lines.
- Flexible Coat Weights – The non-contact coating method permits elongation of the adhesive until the desired coat weight is achieved. Coat weights from 1 to over 100 gsm are achievable “on-the-fly” dependent upon the adhesive rheology.
