    配方类型: TEXTILES AND THEIR TREATMENT
    配方说明: Backcoating Silver-Knit Fabrics
    配方组成: Durability to drycleaning and washing is obtained when silver-knit
    fabrics are backcoated with
    "Nopco" DF 160L (diluted 1:1 with water)/0.2
    Ammonium hydroxide (28% NH3)/2.1
    "Rhoplex" TR 520/48.2
    "Acrysol" ASE-60/4.4
    Water/39.5
    Water premix/4.4
    Ammonium chloride (25% solution)/1.2
    配制方法: The formulation should be made in the indicated order. Before addition of the diluted "Acrysol" ASE-60, the pH should be measured and adjusted, if below 7.4. A pH in the range 7.4-8.0 is satisfactory.
    Following addition of "Acrysol" ASE-60, the pH may again require adjustment by addition of ammonia to pH 7.4-8.0. The formulation given above has an initial viscosity of about 28,000 cps. and can be applied by knife coater.
    Where dimensional stability alone is required, "Rhoplex" TR-520 can be pigmented with whiting or clay, dispersed with "Tamol" SN, and the formulation can be thickened with "Acrysol" ASE-60. Good fabric stability and a non-tacky hand are obtained with filled formulations of this type, applied by kiss roll or knife coater.
