PPG Transparencies DSS4040 Surface Seal Gen III Coating Common Master Kit

The PPG DSS4040 Common Master Kit is a professional-grade hydrophobic treatment system specifically engineered for glass-faced aircraft transparencies. The Generation III (Gen III) formula represents a significant advancement in rain-shedding technology, providing a more durable, abrasion-resistant barrier compared to previous versions. When applied, it chemically bonds to the glass to create an ultra-slick, low-energy surface that forces water to bead and shed instantly under aerodynamic loads. This kit is essential for maintaining flight safety during terminal operations in heavy precipitation and is often used as a primary means of moisture management for aircraft without mechanical wipers.

• Enhanced Situational Awareness: Dramatically improves visibility for flight crews during approach and landing in rainy conditions.
• Gen III Durability: Optimized to withstand high-velocity sand/dust abrasion and frequent cleaning cycles better than earlier hydrophobic coatings.
• Streamlined Maintenance: The "Common Master Kit" provides a standardized, all-in-one solution for technicians, ensuring all chemical components are fresh and compatible.
• OEM Approved: Qualified for use across a wide range of airframes, including Boeing, Airbus, Gulfstream, and Bombardier, ensuring compliance with Aircraft Maintenance Manuals (AMM).
• Contaminant Resistance: Reduces the adhesion of insects, ice, and salt spray, allowing for easier "wash-off" and preventing long-term etching of the glass ply.

• The DSS4040 Master Kit is designed for a single full-application cycle and typically includes:
• Cleaning & Prep Solutions: To remove all trace oils and contaminants for maximum bonding.
• Gen III Coating Ampoules: The active hydrophobic chemistry.
• Lint-Free Applicator Pads: Engineered for streak-free, uniform distribution.
• Polishing Cloths: For the final buffing stage to ensure optical clarity.

• Scheduled Inspections: Re-application during C-Checks or as required by the operator's maintenance program.
• New Window Installation: Mandatory treatment for new windshields to meet factory rain-shedding specifications.
• Wiperless Aircraft: Critical for aircraft platforms that rely primarily on hydrophobic coatings for rain clearance.

4. Special Customer Requirements
We understand that certain projects, maintenance schedules, or regulatory standards require strict specifications. If your order has specific shelf-life requirements, please proceed as follows:

How to Request: If you require a specific Date of Manufacture (DOM), Date of Expiration (DOE), or a specific minimum shelf-life percentage (%), you must clearly state this requirement:

In the Comments/Notes section when placing an online order.

Explicitly written on your Purchase Order (PO) or quote request email for offline orders.

Validation Process: Once your requirement is received:

We will ship your order if the available stock matches your specifications.

If we do not have the exact batch, we will contact you prior to shipping with the shelf-life percentage (%) or dates we have available for your acceptance.
