KYMC offers two different coating applications which are roll application and pre-metered application. To decide which method to apply, one can reference the criteria list below to help make the decision.
Contamination control:
When the coating requires contamination control, then the pre-metered method is recommended. However, if the coating can accept a small number of debris and contaminants from the environment, then the roll application is recommended for quick change over.
Precision control:
When a very precise coating laydown amount and uniformity are required, then the pre-metered method is recommended. When the laydown amount and uniformity requirement are less stringent, then the roller application can be adopted for a faster coating speed.
Flexibility requirement:
When the viscosity level and coating thickness working ranges are wide, then the pre-metered method is recommended. When viscosity level and coating thickness ranges are more stable within a small range then the roller application is recommended.
Direct Gravure Coating
Application
For a high viscosity level coating that does not require a precise uniformity at high coating speed. Suitable for higher thickness coating requirements.
Product
leather, textile, wallpaper, architectural materials, tape, insulator, packaging
Reverse Gravure Coating
Application
For a medium viscosity level coating that requires more precision and a smoother coating.

Gravure Offset Coating
Application
For an application that requires more control and flexibility over the coating thickness and weight. Suitable for thinner thickness coating requirements.
Product
tape, insulator, packaging, electronics
Micro Gravure Coating
Application
When compared to regular gravure coating, the micro gravure coating has a smaller application roller diameter. This allows for an exceptionally stable coating that is thin and uniform. A reverse micro gravure coating can be applied for a even smoother coating surface when compared to the direct micro gravure coating.
Product
tape, electronics
Flexo Coating
Application
For a low viscosity level coating that does not require a precise uniformity at very high coating speed. Suitable for thinner thickness coating requirements.
Product
tape, insulator, packaging, electronics packaging
Four Roller Coating
Application
For a high viscosity level coating that requires precise uniformity, and at the same time needs the control and flexibility to provide a wide range of coating thickness. It has the ability to lay down a very thin layer of coating.
Product
tape, insulator, packaging, electronics packaging
Slot Die Coating
Application
Suitable for the widest range of viscosity level requirement and coating thickness requirement. Slot die coating is for those who are looking for a maximum control, precision and flexibility.
Product
optical, semiconductor protective films, battery, electronics packaging
