The INVISIBLE SHIELD®PRO 15 Protective Glass Coating is a solvent-extended coating designed for the preservation, enhancement and preventive cleaning of glass used in architectural applications—both commercial and residential—including windows, building facades, glass entrances, walls and partitions, balustrades, shower enclosures, glass blocks and mirrors. It improves the natural characteristics of the glass without changing its physical appearance or transparency. Invisible Shield PRO 15 preserves and protects glass against excessive exposure to water, heat and high humidity that results in corrosion, which makes the glass appear dirty and stained. It makes the glass easier to maintain, improving the clarity and overall appearance of the product. Ultimately, Invisible Shield PRO 15 creates an anti-corrosion and scratch-resistant glass surface that adds longer life to the finished product.

INVISIBLE SHIELD PRO 15 has been manufactured to the highest standards and specifications. It is safe, easy to use, long lasting and storage stable. It should be handled and applied as directed on the product labels and data sheets, and/or Reach and GHS-compliant Safety Data Sheets.

Product Application: Prior to applying Invisible Shield PRO 15, the glass must be thoroughly cleaned to remove any existing dirt, grime, water spots, mineral deposits, or other stains. Be sure to thoroughly rinse and dry the entire glass surface to be treated to remove any excess soil, moisture, or residue from cleaner. Once the glass has been thoroughly cleaned and dried, follow these 3 easy steps to apply the Invisible Shield PRO 15 Protective Glass Coating:

(Step 1) Spray Invisible Shield PRO15 evenly and directly onto the glass surface using an air or airless operated fine mist sprayer, or apply the product to a clean soft cloth, microfiber towel or pad tool to distribute the product directly onto the surface using a firm, circular wiping (polishing) motion making sure to overlap the product for thorough coverage.

(Step 2) Allow the product to dry for 1-2 minutes, or until a slight haze has formed. For optimum protection and to ensure complete coverage, reapply the coating.

(Step 3) Polish the glass with a clean, dry soft cloth or microfiber towel or pad tool until crystal clear. To remove any excess haze, simply spray or rinse the glass with clean water and polish again.

Product Maintenance: The Invisible Shield PRO 15 Protective Glass Coating is extremely durable and will provide continuous protection under most conditions. Although the glass is protected against water, heat and high humidity, the glass is NOT self-cleaning. As with any anti-corrosive glass product or solution, the glass should be cleaned periodically. Windows and building facades should be cleaned on a routine, semi-annual or quarterly basis commensurate with the level of soiling and exposure to weather, dirt, sand, pollution, or environmental contaminants. Glass in shower enclosures and other interior applications should be lightly cleaned on a routine basis (weekly or monthly) using a traditional ammonia-free glass cleaner and commensurate with its use and exposure to dirt, grime, soap, minerals, or hard water. The Invisible Shield PRO15 GLASS COATING is unaffected by normal cleaning with non-abrasive soaps or detergents.

Please follow the guidelines below to ensure the quality of your product.

1) DO NOT USE abrasive (gritty) cleaners of any type, such as but not limited to Soft Scrub®, Ajax® or Comet®. Regular use of a squeegee can also be abrasive and is not recommended, as it will accelerate the wear of the protective coating.

2) DO NOT USE acids, alkalis, or other strong chemicals on the protective coated glass surface.

3) DO NOT USE abrasive cleaning pads or brushes, scrappers, razor blades, or other sharp tools on the protected glass. While the protective coating makes the glass scratch-resistant, it is NOT scratch-proof.

4) ALWAYS USE a clean soft cloth, pad or paper towel to clean the glass.

5) ALWAYS USE compatible cleaning agents, such as a traditional ammonia-free glass cleaner or Repel® Glass & Surface Cleaner manufactured by Unelko Corporation.
