Air Drying One Component Single-Layer Coating – Black

Starting point formulation for an air-drying, one-component anti-corrosion primer, specifically in black color. The formulation incorporates Borchi® Gen 1757 and Borchi® OXY-Coat 1101 for improved performance.

Here's a breakdown of the formulation:

1. Deionized Water: Serves as a solvent.
2. Butyl Glycol/Dowanol DPnB (1:1): Organic solvents for adjusting viscosity.
3. N-Ethyldiisopropylamine 50%ig in Ethanol: Neutralizing agent.
4. Borchi® Gen 1757: Wetting and dispersing agent.
5. Ascotran H10: Flash rust inhibitor.
6. Borchi® Gol LA 50: Facilitates substrate wetting.
7. Borchers® AF 1171: Defoamer.
8. K-White 105, Bayoxide® Z active: Active anti-corrosion pigments.
9. Lamp Black FW 101, EWO, Finntalc M 15: Additional pigments and extenders.
10. Bayhydrol UH 2592: Resin binder.
11. Borchi® Gel 0620, 10% in Butyl Glycol: Rheology modifier.
12. Borchi® OXY-Coat 1101: Co-free drier.

The formulation includes step-by-step instructions for mixing and application, such as dispersing pigments, grinding in a bead mill, incorporating the resin, adding thickener and drier, and adjusting spray viscosity with water.

It also provides specifications for recommended spray viscosity and suggests a flow time of 25-30 seconds in a DIN 4 cup.

The document emphasizes the importance of testing the product for specific applications and adhering to safety and handling instructions.

Additionally, it mentions Borchi® OXY-Coat 1101's features such as good chemical resistance, excellent gloss retention, outstanding pendulum hardness, and good adhesion with no blistering. It also highlights the primer's performance in weathering tests.
