Frosted Glass Coating provides low temperature cure.

Press Release Summary:



Water based Aqua-222, suitable as alternate to acid-etching process for surface alteration of glass containers, cures in 10 min at 350°F in convection oven and in 2.5-3 min at 350°F in IR oven. Low VOC formulation, which bonds chemically to glass, is based on lead-free, cadmium-free glass combined with proprietary processing to create final imitation etches enamel system. Product is resistant to attack by mild acids, alkalis, alcohol and water.



Original Press Release:



Aqua-222* Waterborne Frosted Glass Coatings



Aqua-222 provides low temperature cure not achieved by any other coating process as well as being low VOC and water based. The coatings bond chemically to the glass, thus eliminating the need for high temperature baking, as other glass coatings required.

Applications of Aqua-222 are an alternate to acid-etching process for surface alteration of glass containers involve wine bottles, glassware such as dishes and vases.

Aqua-222 comes in frosted patterns.

Chemical Composition: Aqua-222 formulation is based on a lead-free and cadmium-free glass, combined with a novel processing approach to create the final imitation etches enamel system.

Durability: Good resistance to attack by mild acids, alkalis, alcohol and water, as well as excellent resistance to abrasion and filling line scratching.

Typical Baking (Firing) Conditions
Convection oven: 10 minutes @ 350°F (177°C)
IR Oven: 2.5-3 minutes @ 350°F (177°C)

Ease of Clean up: Flushing with soap and water or mild cleaning agent is usually all that is necessary to clean equipment and screens. For screen plugs, spray with Isopropyl Alcohol, and lightly scrub with clean soft-bristled brush.

Shipping: Shipping can occur immediately after cure and the glass has cooled.

Methods of Application
Surface cleaning of substrate: Like any high quality surface coating, the cleanliness of the substrate is extremely important. Dirt, dust, oil and presence of other coatings on glass substrate can cause surface defects or performance problems. It is strongly recommended that on glass containers either no cold end coating or very light application of cold end coating be used. NO COLD END COATING BASED ON OLEIC ACID SHOULD BE USED. Cold end coating can be reapplied to the coated ware if needed.

Aqua-222 can be supplied ready-to-use for application by traditional wet spraying or brushing coating techniques.

Note: The user of this product should check the performance of this coating before application.
