TECTYL 915W40E Surface Preparation
 The maximum performance of TECTYL 915W40E can be achieved only when the metal surfaces to be protected are clean, dry, and free of rust, oil, and mill scale. It is recommended that the metal substrate temperature be 50 - 95F (10 - 35C) at the time of product application.

TECTYL 915W40E Application
 TECTYL 915W40E 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 915W40E. Incorrect thinning will affect film build, dry time and product performance. t is recommended that the ambient and product temperature be 50 - 95 F (10 - 35C) at time of application. TECTYL 915W40E should be used as factory fill and break-in oil for all new and rebuilt engines. This is a completely operational oil for current production engines meeting the requirements of MIL-PRF-21260E and need not be changed until the first scheduled oil change specified by engine manufacturer. As a preservative coating, TECTYL 915W40E is used to protect engine parts during covered shipment and indoor storage. TECTYL 915W40E is compatible with lubricating oils qualified under MIL-PRF-21260E, MIL-PRF-2104, and MIL-L-46152E.

Removal
 TECTYL 915W40E can be removed with TECTYL HPS solvent borne thinner, vapor degreasing, hot alkaline wash, or low pressure steam. TECTYL 915W40E 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.

Caution
 Refer to the Material Safety Data Sheet for health and safety instructions.

 Note: The addition of any product over or under this coating is not recommended. The use of additional coatings could result in chemical incompatibility, thus adversely affecting the performance of this coating.
