Anti-carburizing Coating KR-AC03L

The anti-carburizing coating is an environmentally friendly, water-based protective coating with excellent application properties and self-drying performance. It is non-corrosive to workpieces and safe for humans. Due to its exceptional wetting properties on metal surfaces, it has less stringent requirements for removing oil residue from workpiece surfaces compared to other coatings.

Category: Anti-Carburizing Coating, Heat Treatment

Storage Conditions

Item Requirements
Storage Temperature 5–40°C. Indoor storage is recommended. Protect from freezing, as freezing may damage the polymer system.
Packaging & Container Requirements Packaged in 200 L plastic drums with a net weight of 200 kg per drum; 25 kg plastic pails or 1,000 kg intermediate bulk containers (IBCs) may also be used.
Shelf Life 2 years. After expiry, the product may only be used after it has been retested and confirmed to meet specifications.
Key Properties (KR9988) Appearance: light yellow to pale red viscous liquid; pH (5% solution): 9.5–10.5; kinematic viscosity (10% solution at 40°C): 3.19 mm²/s.
Precautions Nonflammable and presents no fire hazard; nevertheless, keep the container tightly sealed. If stored outdoors, place the drum horizontally to prevent water, dust, and other contaminants from entering. Retighten the cap immediately after dispensing. Check the concentration with a refractometer before use. PAG-containing products exhibit reverse solubility; polymer separation at elevated temperatures is normal, and the product can be restored by cooling and stirring.
