WATER BARRIER COATING (WBC) is a specialty water-borne barrier coating formulated with a proprietary copolymer emulsion specifically designed for application on paper and paperboard substrates. This advanced coating imparts excellent water repellency, anti-blocking characteristics, and superior oil and grease resistance to the coated paper products. The coating is suitable for flexographic and gravure printing methods and is applied as a non-heat seal coating with a typical coating weight of 5-7 gsm. WBC’s formulation ensures good compatibility with additives and stability over time, making it ideal for both in-line and off-line industrial applications. The eco-friendly water-based composition does not require organic solvents for thinning or machine cleaning, ensuring a cost-effective and pollution-free solution. Additionally, WBC complies with US FDA regulations (21 CFR § 175.105) for food packaging materials, making it safe for indirect food contact applications. Available in packaging sizes from 50 liters to 25 metric tons, WBC is an optimal choice for businesses seeking high-performance water and grease resistant barrier coatings for paper and paperboard in packaging and industrial printing sectors.

Yes, WBC is designed to be used on printed paper and paperboard surfaces to provide oil and grease resistance, but it can also be applied on unprinted substrates as a barrier coating.
No, WBC is water-based and does not require any organic solvents for thinning or cleaning, making it an eco-friendly and cost-effective choice.
The recommended coating weight is between 5 to 7 gsm depending on the type of paper substrate to ensure effective water repellency and barrier properties.
Yes, WBC complies with US FDA regulations (21 CFR § 175.105), making it safe for use in indirect food contact paper packaging.
WBC should be stored sealed and in a cool place. It may develop layer separation over long storage; simple remixing or shaking before use will restore homogeneity.

Shake well before use. This product may develop some soft settling or layer separation over a long period of storage. This can be mixed back to homogenous system by simple mixing.
For good results of water repellency coating must be dried/cured properly with adequate heat flow and sufficient coating weight is required depending up on paper to paper type
APPLICATIONS
• It is designed to be flexo or gravure application. It is used as Non heat seal coatings on paper and paper board with coating 5-7 gsm.
• It is mainly used for as a coating to the printed surface for oil and grease resistance. It can be used for in-line as well as off- line operations.
ADVANTAGES
• Excellent water repellency with cold, hot water and aerated drinks.
• Good resistance to Oil & Grease.
• Provide enough sealing on paper substrate.
• Cost effective
• Very good rub and scuff resistance.
• Good stability and compatibility against additives.
• Water based pollution free, non-hazardous, eco-friendly coating
• No organic solvent required as thinner, diluents or for cleaning of machines, hence economical.
• The constituents of WBC are in accordance with “US Code of Federal Regulations” 21 CFR § 175.105 for food packaging material.
