Anti-corrosion 2K epoxy primer, water-based, gray Deutsche Bahn

Guide formulation for an industrial coating, specifically an anti-corrosion 2K epoxy primer that is water-based and gray in color. It is designed to meet high requirements for mechanical flexibility, adhesion, and corrosion protection, particularly for use in Deutsche Bahn applications. Here's a breakdown of the key information provided:

Product Description & Benefits:

• The formulation is an anti-corrosion 2K epoxy primer suitable for iron and steel alloys.
• It is water-based and gray in color.
• Notably, it is free of active anti-corrosion pigments or inhibitors and offers fast drying and sandability.

Components:

• The primer consists of various components categorized into parts 1 to 4, including demineralized water, additives (such as Texanol), fillers (such as talc and barite), resins (such as Beckopox EP 387w/52WA), and curing agents (such as Beckocure EH 2261w/41WA).

Preparation & Application:

• The document provides instructions for preparing and applying the primer, including mixing raw materials, blending components A and B before application, and dilution with water to achieve the desired spray viscosity.
• Application is typically done using an air spray gun at specified pressure and nozzle size.

Technical Data:

• The guide includes technical data such as mixing ratios, crosslinking ratios, solids content, pH, density, and various performance properties (e.g., fineness of grind, viscosity, pendulum hardness, cupping test, humidity test, etc.).
• Performance tests are conducted on different substrates (e.g., cold-rolled steel, deep drawing steel, blasted steel, blasted aluminum) to assess adhesion, hardness, corrosion resistance, and other properties.

Suppliers:

• Suppliers for various raw materials used in the formulation are listed, including Allnex, Eastman Chemical Company, HOFFMANN MINERAL, Kronos International, and Lanxess.

Disclaimer:

• The document includes a disclaimer stating that the information provided is non-binding advice without guarantee, and the company cannot be held responsible for any damages resulting from the use of the data and recommendations.

Overall, this guide formulation serves as a comprehensive resource for formulating and applying an anti-corrosion epoxy primer suitable for industrial applications with stringent requirements for mechanical flexibility, adhesion, and corrosion protection.
