TwinCoat™ - Non-Contact Dual Slot Die Applicator
TwinCoat™ is the only adhesive applicator in the market that has the unique ability to split the required amount of adhesive into two layers and apply them simultaneously on a substrate.
Overview
- Dual Adhesive Coating – Two layers combined in one, with just one applicator and in only one production step.
- Rapid Adhesive Changeover – quickly and easily switch from adhesive Type A to adhesive Type B.
- 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.

The Dynatec Difference
TwinCoat’s immediate benefits are obvious: putting adhesive films on top of or next to each other, increasing product quality and decreasing product costs. The two different adhesives can also be applied in succession. Conventionally, an adhesive change requires a costly, line-stopping system changeover. This is almost completely eliminated with the use of TwinCoat. If a production cycle completed, it can be quickly and easily switched from adhesive Type A to adhesive Type B. After a brief rinse of the nozzle lip by adhesive Type B, the system can go back into operation immediately. The entire changeover process takes no more than 1-2 minutes, delivering a drastic reduction in downtime and a significant increase in productivity. Additionally, TwinCoat system cleaning uses 90% less adhesive, delivering a further reduction in production costs.
