Tectyl 891D 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 Storage
Store TECTYL 891D, Class I at
temperatures between 50-95°F (10-35°C).
Mild agitation is recommended prior to use.
Tectyl 891D 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 product
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 product
performance. Daubert Chemical Company
recommends that the ambient and product
temperature be 50 - 95°F (10 - 35°C) at time
of application. TECTYL® 891D, Class I can
be spray or dip applied.
Tectyl 891D Caution
Adequate ventilation is required for cure and
to ensure against formation of a combustible
liquid.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 891D 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.
