The major hazards encountered in the use and handling of 2,4-diamino-6-phenyl-1,3,5-triazine stem from its toxicologic properties. Toxic by inhalation and ingestion, exposure to this crystalline substance may occur from its use in the manufacture of thermosetting resins, and as a chemical intermediate for pesticides, pharmaceuticals, and dyestuffs. In activities and situations where over exposure may occur, wear a self-contained breathing apparatus and personal protective clothing. If contact should occur, immediately flush affected skin or eyes with running water for at least 15 minutes. Remove contaminated clothing and shoes at the site. While this substance does not ignite easily, it may burn with the production of irritating and poisonous gases. For fires involving this substance, extinguish with dry chemical, CO2, Halon, water spray, fog, or standard foam. This substance may be shipped via air, rail, road, and water, in containers bearing the label "Poison". Small dry spills of this substance may be placed into a clean, dry, covered container for later disposal (liquid solutions are first absorbed in sand or other noncombustible absorbent). Large liquid spills should be diked far ahead to prevent this substance from entering water sources and sewers. Before implementing land disposal of this substance, consult with regulatory agencies for guidance.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 130(SRC), determined from a log Kow of 1.36(2) and a regression-derived equation(3), indicates that 2,4-diamino-6-phenyl-1,3,5-triazine is expected to have high mobility in soil(SRC). Volatilization of 2,4-diamino-6-phenyl-1,3,5-triazine from moist soil surfaces is not expected to occur(SRC) given an estimated Henry's Law constant of 4.1X10-11 atm-cu m/mole(SRC), using a fragment constant estimation method(4). 2,4-Diamino-6-phenyl-1,3,5-triazine is not expected to volatilize from dry soil surfaces based on an estimated vapor pressure of 1.2X10-7 mm Hg(SRC), determined from a fragment constant method(5). Biodegradation data were unavailable for 2,4-diamino-6-phenyl-1,3,5-triazine(SRC), but triazine compounds, in general, are slowly biodegraded(6).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 130(SRC), determined from a log Kow of 1.36(2) and a regression-derived equation(3), indicates that 2,4-diamino-6-phenyl-1,3,5-triazine is not expected to adsorb to suspended solids and sediment in water(SRC). 2,4-Diamino-6-phenyl-1,3,5-triazine is not expected to volatilize from water surfaces(3,SRC) based on an estimated Henry's Law constant of 4.1X10-11 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4).

Biodegradation data were not found for 2,4-diamino-6-phenyl-1,3,5-triazine(SRC), but triazine compounds, in general, are slowly biodegraded(6).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 2,4-diamino-6-phenyl-1,3,5-triazine, which has an estimated vapor pressure of 1.2X10-7 mm Hg at 25 °C(2,SRC), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase 2,4-diamino-6-phenyl-1,3,5-triazine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 4.4 days(3,SRC).

The Koc of 2,4-diamino-6-phenyl-1,3,5-triazine is estimated as approximately 130(SRC), using a log Kow of 1.36(1) and a regression-derived equation(2,SRC). According to a classification scheme(3), this estimated Koc value suggests that 2,4-diamino-6-phenyl-1,3,5-triazine is expected to have high mobility in soil(SRC). Adsorption of 2,4-diamino-6-phenyl-1,3,5-triazine, 5X10-5 M, by Na-montmorillonite at four pH levels was approximately 310 umol/g at pH 1, 460 umol/g at pH 2, 475 umol/g at pH 4, and 200 umol/g at pH 6.5; maximum adsorption by the clay occurred at pH levels in the vicinity of the pKa, 3.7(4). This compound's pKa of 3.7(4), indicates it will exist predominately in the unionized form under environmental pHs(SRC). Weak bases, such as 2,4-diamino-6-phenyl-1,3,5-triazine, are more mobile in alkaline soils because cations are much more strongly adsorbed by ion exchange on organic and inorganic surfaces than the unionized bases are by organic matter(5).

Painting (Pigments, Binders, and Biocides) [Category: Paint]

Thermosetting resins, resin modifiers; chemical intermediate for pesticides, pharmaceuticals, and dyestuffs

In industrial paints; addition of benzoguanamine to baking enamels based on melamine alkyd resins leads to increased gloss, elasticity, and stability toward alkali; used in the preparation of daylight fluorescent paints to increase their resistance to weathering; benzoguanamine is also an effective stabilizer for aqueous formaldehyde solutions, preventing the separation of formaldehyde polymers.

Used in amino resins for coatings because it provides excellent resistance to laundry detergent.
