Wintrol B-E is benzotriazole in a crystalline, fibrous like acid form. This product does prove faster dissolution into solutions vs. the granular or flake forms.

Wintrol B-P is benzotriazole is its powder, acid form. This is typically a niche product which contains an anti-caking agent.

Wintrol T is tolyltriazole is its granular acid form. The product is a mixture of two isomers, 4 methyl & 5 methyl benzotriazole. Liquid forms of tolyltriazole as acid are available, this product form could work well at times formulated directly into an alkaline or hydrocarbon formula.

Wintrol B-20EG is benzotriazole as acid dissolved in ethylene glycol. The product is intended for use in glycol solutions.

Wintrol T-50Na is the liquid sodium salt of tolyltriazole. The product is a mixture of two isomers, 4 methyl & 5 methyl benzotriazole, sodium salt. This is the most widely used form of any triazole.

Wintrol T-35IP/IPW is 35% solution of tolyltriazole in isopropyl alcohol. This liquid corrosion inhibitor is easy to handle and is typically used in the following applications: metalworking fluids, cleaners, direct treatment and inks.

Wintrol 42 is a modified tolyltriazole compound geared towards use within the neutral pH range. This product is Made in the USA.

Wintrol B-45IP/IPW is benzotriazole as acid dissolved in isopropanol. This product has worked well in several direct metal treatment applications.

Wintrol T-Na is the solid, sodium salt of tolyltriazole. The product is offered as a fine powder. The product is a mixture of two isomers, 4 methyl & 5 methyl benzotriazole. This product is nearly miscible in water and designed for use when solid additions are preferred.

Wintrol CT is 50% sodium tolyltriazole Made in the USA. This is the most widely used form for yellow metal corrosion protection

Dober Chemical Corp. D16 (Auto/Light-Duty) is a single component additive system used to blend Auto/Light-duty, extended life coolants meeting ASTM D3306 standards. This additive package contains extended life corrosion inhibitors based on organic acids and provides maximum protection against damaging rust and corrosion in engine cooling systems. This inhibitor package is free of nitrite, amine, phosphate and silicate. This patent pending technology does not use 2EH acid nor any other organic acid that is aggressive to hoses and gaskets.

Wintrol T-40DG is 40% tolyltriazole in diethylene glycol. This liquid product is easy to handle an can be used in the following applications: engine coolants, metal working fluids, lubricants, inks and cleaners.

Wintrol T-35 PG/PGA is 35% tolyltriazole is propylene glycol. This liquid corrosion inhibitor provides easy product handling and can be used in applications such as heat transfer fluids, engine coolants, lubricants and cleaners.

Wintrol 39 is a oil-soluble modified tolyltriazole. This liquid material blends directly into common mineral oils without the need for a co-solvent.

Wintrol B-G is benzotriazole is its granular, acid form. Liquid forms of benzotriazole as acid are available, this product form could work well at times formulated directly into an acid formulation at lower concentrations.

Wintrol B-F is benzotriazole is its flake, acid form. Liquid forms of benzotriazole as acid are available, this product form could work well at times formulated directly into an acid formulation at lower concentrations.

Wintrol B-40Na is the liquid sodium salt of benzotriazole. In contrast to the more widely used 50% Na-TTA, this 40% Na-BTA solution is used within similar formulas.
