Vantage iSAP 311 is an advanced, non-chromated inhibited surface adhesion promoter engineered by Vantage Specialties to clean and protect critical aerospace structures immediately prior to painting. Formulated to optimize surface energy and coating anchor profiles, this specialized chemical agent functions seamlessly with both chromated and non-chromated paint systems. By providing a clean, passivated molecular layer, iSAP 311 actively prevents underlying structural degradation while dramatically enhancing the interfacial bonding strength of primers and topcoats. Its specialized formulation ensures absolute multi-metal compatibility, preventing hydrogen embrittlement or structural etching on high-strength aviation alloys during standard flight-line and depot prep cycles.

Typical Applications

• Pre-Paint Airframe Surface Preparation: Applied manually or via spray methods onto exterior fuselage panels and wing structures immediately before primer application to prevent coating failure or peeling.
• MRO Component Refurbishment: Used across aerospace maintenance depots to clean, deoxidize, and passivate removed components prior to paint line entry.
• Flight Line Spot Repairs: Ideal for localized coating touch-ups and composite/metal bonding preparation where robust adhesion tracking is necessary.

At Aircraft Shop Supply, we are committed to shipping the highest quality and freshest product possible. To ensure efficient stock rotation and meet aviation industry standards, our inventory management is governed by the following policy:

1. Scope of Application
All Sales Channels: This policy applies to all orders processed by Aircraft Shop Supply, including but not limited to: website purchases, direct email orders, formal Purchase Orders (POs), phone orders, and contract agreements.

2. Inventory Management (FIFO)
All products with an expiration date are managed and shipped on a strict "First In – First Out" (FIFO) basis.

3. Minimum Shipping Margin
Standard Guarantee: We will not ship any products with fewer than 30 days of use remaining (days before expiration), unless previously coordinated and agreed upon with the customer.

No Automatic Guarantees: Outside of this 30-day minimum margin, Aircraft Shop Supply does not make any automatic guarantee as to the specific length of time remaining on any shelf-life item for standard orders.

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.

5. Limitation of Liability and Validity of Information
To ensure transparency and manage expectations, the following terms and conditions apply:

Time-Limited Validity: Any information provided by our team regarding the remaining shelf-life percentage (%) is valid only at the exact time the inquiry is made. Due to high inventory turnover, availability is subject to change without prior notice.

Informational Purposes Only: Shelf-life data provided by Aircraft Shop Supply is strictly for informational purposes and reflects the availability at the moment of inquiry. It does not constitute a batch reservation or a product warranty.
