Brief introduction:
Liside CU is an efficient cyclic phosphonate flame retardant for the treatment of
textile products. It is non-corrosive with high phosphorus content, excellent water
solubility on a wide range of fabric type. It mainly used in furnishing, curtaining,
building, special workwear and automotive applications. It is particularly
suitable for the treatment of polyester fabric, T/C blends and PU coating to impart
a finish that is durable to washing and dry-cleaning.

Specifications:
1) Appearance: clear highly viscous liquid
2) Color number: 100 max.
3) Phosphorus (Wt%): 20.5% min.
4) Acid Number (mg, KOH/g): 15 max.
5) Density (g/cc at 25deg;C): 1.21.3
6) Viscosity at 20°C (Cps): 150,000 max.
7) Flash point: 165°C
8) DMMP assay (Wt%): 0.5% max.
9) TMPP assay (Wt%): 0.5% max.
10) Durable to washing times: 50 times min.

Properties:
1) High heat stability and good retain of hand feel and drape after 
    processing
2) Low volatility and good compatibility to major polymer
3) Little discoloration after treatment
4) High durability to washing and good retain of color brightness
5) Non-toxicity and high safety

Typical application process:
1) Treatment of polyester fabric and T/C blends
    a) Recommendatory formulation:
        i) Flame retardant: 6 - 15kg
        ii) Added water, 20kg: stirred evenly
        iii) Added 20% conc. Na2HPO4 
            or Na2CO3: 4 - 8kg pH is buffered to 
            5.5 - 6.5 or 25% conc. aqua ammonia
        iv) Added penetrating agent: 0.05 - 0.2kg mixed evenly
        v) Additional water: diluted by water to 100kg
    b) Procedure:
        i) Fabric for treatment with flame retardant should be clean and 
           absorbent. Starch and other sizes should be removed before 
           processing
        ii) Fabric shall be treated by padding, dipping according to fabric 
            composition, weight and construction
        iii) 120 - 140°C x 60sec, pre-drying
        iv) High temperature thermo-fixation process
        v) Cooling, rolling up the treated fabric. To improve the hand feel, 
            fabric can be cleaned again if necessary to remove the un-affixed 
            flame retardant on the fabric
2) Coating treatment of polyester fabric and PU fabric
    a) The formulation is dried and cured in a single pass at 150°C for 120
        seconds
    b) The formulation is buffered to pH 5 using sodium carbonate. The  
        added amount of soda ash is about 0.4%
