Rapid Prototyping

Carestream’s highly flexible coating assets, combined with our experienced technical and business teams, enable rapid material and product screening, small product sample coating and testing, and efficient scale-up to pilot and production coating equipment. We work with our partners to quickly adjust formulation and coating conditions for low-cost, small-run and experimental multilayer coating projects.

Coating Assessment Laboratory (CAL):

• Ability to generate precision-coated prototype samples up to six feet long using only a few grams of solution.
• Provides small-scale, roll-to-roll coating for up to 12-inch wide films, foils, paper and membranes, for larger prototype quantity requirements.
• Contains custom mixing, solution delivery, coating, drying and analytical equipment used for small-scale, early-stage product and process development.
• Ability to predict how a given coating solution and substrate system will behave in various manufacturing operations before scaling up to larger pilot-scale and manufacturing-scale equipment.

Pilot Coating:

• Proprietary coating techniques, enhanced drying methods and streamlined solution delivery systems.
• Ability to simultaneously use multiple coating techniques at our different locations to enhance collaboration, execute rapid prototyping and scale-up projects, and troubleshoot issues.
• Pilot coaters modeled after larger coaters to ensure seamless transfers to full-scale manufacturability.

Production Coating:

• Enables mass production of commercial products at minimal cost and reduced time-to-market for customers coating advanced material solutions onto flexible substrates.
