Product Overview BK is a highly effective fungicide for water-based products, particularly suitable for high temperature environments and alkaline systems. Its unique production process, making high purity, the smell is very small, increase product stability and no discoloration. BK is a slow-release biocide, its slow release gives long-lasting antibacterial liquid processing function to prevent corruption and foul-smelling odors, to ensure the safe operation of the system. Features l for EC, fully synthetic, semi-synthetic and under its processing liquid l high temperature environments and an alkaline environment, stable performance l sustained-release fungicides, long-lasting protection products l easily used in conjunction with other active ingredients of this product l can be added in any process, no requirement for application of the system and adverse effects. Product physical and chemical indicators Appearance yellow transparent liquid pH (0.2% aqueous solution) 9.0-11.0 (0.1% aqueous solution of 9.0-10.5) Density (25 ℃) 1.150-1.160g / ml (1.030-1.080) solubility can be dissolved in any ratio Deionized water and standard hard water (3mmol Ca ions / l), soluble in alcohol and propylene glycol, and the spindle oil-immiscible. Applications BK as fungicides may be used alone, or used in other fungicide compound. Working solution concentration: 0.1 --- 0.15% (by weight) (0.1-0.25%) concentrate concentration: 2 --- 3% (2-5%) analysis of trace metal content of the product indicates that the product Trace metal contamination of less than 10 ppm. Antimicrobial activity (no) BK kill microbes and fungi, said the effect of the minimum inhibitory concentration: Organic MIC (ppm) of Bacillus subtilis NCTC 10073 1000 Bacillus cereus NCOO 2599 500 Staphylococcus aureus NCIB 9518 500 gram-negative Klebsiella pneumoniae bacteria PC 1602 500 gas Klebsiella (s) bacillus Pseudomonas aeruginosa NCTC 418 500 NCIB 8626 500 Burkholderia cepacia NCIB 9085 500 Pseudomonas fluorescens NCIB 9046 500 aerogenes NCIB 9034 500 yeast Candida albicans ATCC 10,231,500 Saccharomyces cerevisiae NCTC 87 500 mold mildew IMI 82021 500 grape spike rope IMI 87160 500 Penicillium Aspergillus niger ATCC 16404 1000 viride (industrial separation) 1000 BK toxicity index is low to moderate acute toxicity, acute oral rat toxicity LD50 about 1000mg / kg, rabbit skin acute toxicity LD50> 2000mg / kg. In vitro and in vivo studies have shown that: its rabbit skin stimulation of Guinea pig to reach a concentration of 0.4% non-allergenic. If swallowed (R22) and irritation of the eyes (R36), also have hurt, BK easy to decompose in the environment. However, if there is no pre-treatment, the product can not be placed directly into the gutter. HANDLING AND STORAGE BK stored at room temperature the shade. In the unopened containers, which storage period of at least 24 months. Once the barrel is turned on and remove some of the materials must be immediately closed. Avoid contact with eyes and skin. When handling concentrated product must wear goggles.
