Description
TECTYL 848DHF is a high-performance, solvent-based light oil corrosion preventive compound manufactured by Daubert Chemical Company, Inc., specifically designed to provide reliable protection for ferrous and non-ferrous metals, particularly CNC (Computer Numerical Control) machinery parts. This thin film rust preventive is formulated in aliphatic solvents and creates a light, transparent, sometimes non-discernable protective film that effectively prevents corrosion while penetrating cracks and crevices of metal components. With its quick-drying, low-viscosity formula, TECTYL 848DHF offers exceptional protection during in-plant processing, transit, and storage, making it an ideal solution for short-term rust prevention in indoor environments.

Application Guidelines
- Product Preparation: Formulated to be used as supplied; ensure uniform consistency prior to use
- Stirring Requirements: Continued stirring generally not required
- Temperature Control: Apply when ambient and product temperature is 50-95°F
- Application Methods: Can be applied by spray, brush, dip, or roller
- Thinning: DO NOT THIN; incorrect thinning will affect film build, dry time, and product performance
- Cold Storage Issues: If product thickens due to cold storage or loss of solvent during use, contact Daubert Chemical Company
