Cellulose fabric composed of permanent flame retardant FR-313: reactive organic nitrogen and phosphorus flame retardant Technical Specifications: Appearance: transparent viscous liquid active ingredient content: ≥15% acid value (mg KOH / g): ≤10 gravity (g / cm3 @ 25 ℃): 1.1 ~ 1.2 Viscosity (Cps @ 25 ℃): ≤20 washable number: ≥50 times performance FR-313 is a colorless, transparent liquid, nitrogen and phosphorus system reactive flame retardant. Able to freely cellulose reactive groups and hydroxyl chemical combination is also known as permanent cellulose flame retardant. This product is highly flame retardant efficiency, activity, and can be stable in water, and cellulose reaction after fixing performance is very stable and non-toxic and environmentally friendly. FR-313 is water-based flame retardants, are environmentally friendly products. Colorless and transparent appearance is not easily affect on the fabric, or the pigment is relatively small damage to the fabric. Use products are widely used in cotton and other cellulose-based viscose fabric, pre-treatment before use to ensure the fabric is clean and free of oil, wetting agents may be used, if necessary, so that the flame retardant can be well combined with cellulose . FR0313 nontoxic, can be used for curtains, blankets, Jackets, tents, industrial canvas, fire clothing and many other occasions to use FR-313 using a simple, straightforward way using padding or spraying the surface of the fabric. After 1-2 minutes, 150 ℃ drying can be. Washed with water if necessary and dried. Packing: 25 kg / barrel, 50 kg / barrel
