Protectol HT Equivalent, IR-Triazine


Product Info:

IR-Triazine is a 76% solution of Hexahydrotriazine. It is the Protectol HT Basf biocide equivalent product. This chemical is a formaldehyde-release biocide. And it is particularly suitable for use as a desulfurized and anti-mildew agent. In addition, this Protectol HT equivalent is particularly suitable as a preservative in metalworking fluids, adhesives, industrial additives, polymer dispersions, and chain lubricants.


IR-Triazine is a clear, colorless, slightly yellowish solution. And it can be regarded as a high-quality “Hexahydrotriazine” because of its purity, odor, stability, and color. This Protectol HT equivalent is a formaldehyde-release biocide. So the range of activity has similar to that of formaldehyde. Different pH and temperatures have different impacts on the release of formaldehyde. Generally, the lower the temperature, the lower the amount of formaldehyde. In addition, the release is greater at lower pH.

The Minimum Inhibitory Concentrations (M.I.C.) against a range of test organisms are displayed in the following table. M.I.C. data is generated according to in-house methodology.


IR-Triazine can be solved or mixed in all proportions with water, alcohols, glycols, and other polar organic solvents. This characteristic makes dosing and treatment easier in various industrial product matrices. It can be used as a stand-alone preservative or with other biocides. This equivalent biocide of Protectol HT is biodegradable. And it is an aqueous solution of hexahydrotriazine. IR-Triazine has compatibility with nonionic, cationic, and anionic surfactants.

Like Protectol HT, IR-Triazine is also used to preserve the oil and gas industry, such as drilling fluid, shelf fluid, completion fluid, and oilfield additive. In addition, it is used to preserve processing additive and bulk paper in the paper industry.

This product works well as a preservative in alkaline products. It is particularly effective as a preservative for metalworking fluid concentrates and tank-side addition to the dilute emulsion. This Protectol HT equivalent is compatible with various raw materials for formulating industrial products.

To inhibit the growth of spoilage microorganisms during manufacture, storage, and distribution, Protectol HT may be dosed at between 150~1500ppm based on the final formulation volume. Lower concentrations are required if Protectol HT is used with other active substances.

Storage and packing:

IR-Triazine is stable for up to 24 months when stored in sealed containers and used for the in-can preservation of water-based paints and prevention of bulk spoilage during shelf-life.

Safety and hazards:

IR-Triazine is readily biodegradable in the environment. However, the product should not be discharged into the waterways without prior treatment.

Inhalation: If inhaled, move the patient to fresh air.

Skin contact: In contact with skin, immediately remove contaminated clothing and rinse skin thoroughly with soap and water. Seek medical attention if you feel unwell.

Eyes contact: Separate the eyelids and rinse with running water or saline. Seek medical attention immediately.
