Tectyl 859B

TECTYLŽ 859B is a contact and volatile corrosion inhibiting compound. It is intended for use as a preservative/additive for enclosed systems where volatile components provide protection above the oil level. TECTYLŽ 859B can be used as a contact preservative. TECTYLŽ 859B conforms to Military Specification MIL-PRF-46002C, Grade 1.

Tectyl 859B Surface Preparation
The maximum performance of TECTYL 859B can be achieved only when the metal surfaces to be protected are clean, dry, and free of rust, oil, and mill scale. Daubert Chemical Company recommends that the metal substrate temperature be 50 - 95°F (10 - 35°C) at the time of product application.

Tectyl 859B Application
TECTYL 859B is formulated to be used as supplied. Ensure uniform consistency prior to use. Continued stirring is generally not required. If the product thickens due to cold storage or loss of solvent during use, contact Daubert Chemical Company. DO NOT THIN TECTYL 859B. Incorrect thinning will affect film build, dry time and product performance. Daubert Chemical Company recommends that the ambient and product temperature be 50 - 95°F (10 - 35°C) at time of application. TECTYL 859B can be applied by spray or flush, or added to enclosures as recommended. TECTYL 859B is not intended for use as an operational preservative oil and should not be used in applications where rubber components are present. Vapor protection is not effective unless an adequate reservoir of oil can be maintained. A minimum of five fluid ounces of TECTYL 859B should be used for each cubic foot of vapor space or five liters for each cubic meter of vapor space.

Tectyl 859B Caution
Adequate ventilation is required for cure and to ensure against formation of a combustible atmosphere. THE PARTIALLY CURED FILM SHOULD NOT BE EXPOSED TO IGNITION SOURCES SUCH AS FLARES, FLAMES, SPARKS, EXCESSIVE HEAT, OR TORCHES. Refer to the Material Safety Data Sheet for additional handling and first aid information.

Tectyl 859B Removal
TECTYL 859B can be removed with TECTYL HPS solvent borne thinner, vapor degreasing, or low pressure steam. TECTYL 859B can be removed from fabrics by normal dry cleaning procedures. Avoid the use of chlorinated or highly aromatic solvents when removing from painted surfaces, as these solvents may adversely affect paint.
