Application of TEKTAMER 38 AD
Tektamer 38 AD is a biocide based on the antimicrobial active ingredient dibromodicyanobutane.
Tektamer 38 AD is a full spectrum biocide and can be used in controlling bacteria, mold and yeasts.
Tektamer 38 AD is a white to off-white dispersion.
Tektamer 38 AD is best used as a biocide in products that have a pH ranging from acidic to weakly alkaline.
This makes it possible for Tektamer 38 AD to be added at various stages of the production process.
In case higher temperatures (> 140 °F/60 °C) or pH values > 9 are to be expected in subsequent processing stages, the product should be added later, since under such conditions Tektamer 38 AD may be subject to accelerated degradation.
Tektamer 38 AD is compatible with most formulation components (raw materials, additives).
However, the presence of strong nucleophiles such as sulfurous compounds (hydrogen sulfite, mercaptans, etc.) or amines can cause ineffectiveness.
To obtain reliable and reproducible results, homogeneous distribution in the materials to be protected must be ensured by taking suitable measures in production (stirring, agitating, etc.).
As with any product, use of the products mentioned in this publication in a given application must be tested (including field testing, etc.) by the user in advance to determine suitability.
Material compatibility of Tektamer 38 AD
For the handling of Tektamer 38 AD it is recommended to use plastics wherever possible for the required equipment (stirrers, hoses, containers, seals, pump parts, etc.).
When using metallic materials, their corrosion resistance must be tested prior to using Tektamer 38 AD is compatible with materials such as PVC, polyethylene, polypropylene, Tygon, Teflon and glass. Tektamer 38 AD is corrosive to mild steel. Positive displacement pumps are preferred for handling and dosing the product.
As with any product, use of the products mentioned in this publication in a given application must be tested (including field testing, etc.) by the user in advance to determine suitability.
Tektamer 38 AD is a powdered or liquid material which can be added to clay slurries and bodies to prevent the growth of fungus and bacteria which affect plasticity and produce unpleasant odors.
When glazes contain organic gums, for example, this can become an issue.
Products like this can affect glaze viscosity over time so there may be a need to adjust with a flocculant or deflocculant.
In worst-case scenarios, glazes can thin and settle in the bucket.
Directions for use of Tektamer 38 AD
Tektamer 38 AD is a violation of U.S. Federal law to use this product in a manner inconsistent with its labeling.
Tektamer 38 AD is an effective preservative in many compositions. The quantities required to give protection depend on several factors, particularly the nature and the sensitivity of the products to be preserved, the pH value, the initial microbial content, the extent of expected contact with microorganisms and the envisaged duration of storage. The quantity of biocide required can be optimized by taking additional hygienic measures during production, storage and transport.
On account of the numerous preservation problems that occur in practice, it is recommended to conduct trials at different concentrations in order to test compatibility, stability and biological effectiveness.
Application of Tektamer 38 AD
Aqueous paints (including heating and air conditioning systems)
Incorporate into the makeup water during the grind.
Latex emulsions
Add using moderate agitation immediately following the cool-down of the emulsions and prior to pumping to storage tank facilities.
Adhesives
Incorporate with agitation to the make-up water. However, where the adhesive is heated, Tektamer 38 AD should be added during the cool-down cycle.
Waxes, polishes, and inks
Incorporate with agitation into the make-up water blend.
Dispersed pigments
Add using moderate agitation immediately following the cool-down of the dispersed pigment and prior to pumping to the storage tank facilities.
Joint cements
Incorporate with agitation into the make-up water blend.
Metalworking fluids
Add to the final diluted cutting fluid, either prior to its addition to the system, or after the system has been filled.
Tektamer 38 AD should be thoroughly mixed into the system to assure efficacy.
If Tektamer 38 AD is added to the concentrate, testing should be done to assure compatibility.
Fiber processing fluids
Add to the make-up water of emulsions or to oil with agitation.
As with any product, use of the products mentioned in this publication in a given application must be tested (including field testing, etc.) by the user in advance to determine suitability.
First aid measures of Tektamer 38 AD
First-aid measures general :
In case of accident or if you feel unwell, seek medical advice immediately .
Move the affected personnel away from the contaminated area.
First-aid measures after inhalation :
Remove person to fresh air and keep comfortable for breathing.
If not breathing, give artificial respiration.
Get immediate medical advice/attention.
First-aid measures after skin contact :
Wash with plenty of soap and water.
Remove contaminated clothing and shoes.
Get immediate medical advice/attention.
First-aid measures after eye contact :
Immediately flush eyes thoroughly with water for at least 15 minutes.
Remove contact lenses, if present and easy to do.
Continue rinsing.
Get immediate medical advice/attention.
First-aid measures after ingestion :
Do NOT induce vomiting.
Never give anything by mouth to an unconscious person.
Rinse mouth out with water.
Get immediate medical advice/attention.
Storage of TEKTAMER 38 AD
Stored properly in sealed containers, the product has a shelf life of 12 months.
Avoid storage below 41°F (5 °C) and 102 °F (39 °C).
Keep from freezing.
Store away from heat.
Freeze-thaw cycle may cause a temporary water separation that can be corrected by mechanical agitation.
TEKTAMER 38 AD may separate during long term storage.
If the product has noticeably separated, mechanical agitation can be used to achieve a uniform dispersion.
At temperatures above 102 °F (39 °C), the active ingredient in the aqueous dispersion may separate out.
Temperature changes may alter viscosity, but should not affect handling or performance.
