TECTYL 891D, Class 1 Surface Preparation:
The maximum performance of Tectyl 891D Class I 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 891D, Class 1 Application:
Tectyl 891D, Class I is formulated to be used as supplied. Ensure uniform consistency prior to use. Continued stirring is generally not required. If the Tectyl 891D thickens due to cold storage or loss of solvent during use, contact Daubert Chemical Company. DO NOT THIN TECTYL 891D, Class I. Incorrect thinning will affect film build, dry time and Tectyl 891D performance. Daubert Chemical Company recommends that the ambient and Tectyl 891D temperature be 50-95°F (10-35°C) at time of application. Tectyl 891D, Class I can be spray or dip applied.
TECTYL 891D, Class 1 Removal:
Tectyl 891D, Class I can be removed with Tectyl HPS solvent borne thinner, vapor degreasing, hot alkaline wash, or low pressure steam. Tectyl 891D, Class I 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.
TECTYL 891D, Class 1 Storage:
Store Tectyl 891D, Class I at temperatures between 50-95°F (10-35°). Mild agitation is recommended prior to use.
TECTYL 891D, Class 1 Caution:
Adequate ventilation is required for cure and to ensure against the formation of a combustible liquid. THE PARTIALLY CURED TECTYL 891D FILM SHOULD NOT BE EXPOSED TO INGITION SOURCES SUCH AS FLARES, FLAMES, SPARKS, EXCESSIVE HEAT, OR TORCHES. Refer to the Material Tectyl 891D Safety Data Sheet for additional handling and first aid information.
Tectyl 891D, Class 1 Note:
The addition of any product over or under the Tectyl 891 is not recommended. The addition of additional coatings could result in chemical incompatibility, thus adversely affecting the performance of the Tectyl 891 stated in the lab data section. If a product other than Daubert Chemical Company's Tectyl 891 is required, written authorization must be obtained from Daubert Chemical Company.
