Product catalog summary
Introduction to CrossCoat™ Technology
ITW Dynatec's CrossCoat™ is a non-contact, metered slot applicator designed for precise adhesive application, ensuring streak-free coating results. It forms a continuous film from the applicator to the substrate, achieving cross-web accuracies of ±3% with a minimum coat weight of 1gsm at speeds of 1,000 m/minute or more.
Performance and Precision
The CrossCoat™ system offers precision and flexibility, encapsulating surface contaminants to maintain consistent coating performance and minimize waste. Integrated gear pumps ensure exceptional cross-web distribution accuracy, and coat weight and coverage width can be adjusted automatically or manually.
Non-Contact Application Benefits
This technology is ideal for heat-sensitive materials, as it prevents contact with the die lip, avoiding damage. It conforms to irregular surfaces, ensuring 100% coating on fabrics and textured materials. The non-contact method allows for flexible coat weights from 1 to over 100 gsm, depending on adhesive rheology.
Technical Specifications
Adhesive viscosity ranges from 1,000 to 200,000 cps, with a maximum operating temperature of 200º C (425º F). Pneumatic pressure ranges from 5 to 9 bar, and adhesive pressure from 7 to 68 bar. Various pump sizes are available, with outputs ranging from 0.63 to 634.36 lbs/hr.
Contact Information
ITW Dynatec has offices in Europe, Africa, the Middle East, Japan, the Americas, and Asia, providing global support and service.

CrossCoat Precision Metering Slot Die-1

The Next Level of Technology CrossCoat™ Precision Metering Slot Die ITW Dynatec’s CrossCoat™ is a non-contact, metered slot applicator that produces a precise flow of adhesive for coating applications that require streak-free results. A continuous film is formed from the applicator to the 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. CrossCoat™ Precision Metering Slot Die: • 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. Precision Integrated gear pumps provide exceptional cross-web distribution accuracy to ±3%. Flexibility Coat weight and coverage width can be easily changed automatically or manually. Performance Non-contact application encapsulates surface contaminants instead of trapping them between the die lip and substrate, producing consistent coating performance while minimizing waste. ITW Dynatec - CrossCoat™ Precision Metering Die The Dynatec Difference... Non-Contact Application 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.
