Ⅰ Product Composition: Poly(Dimethyl Diallyl Ammonium Chloride) polydadmac Curing Agent   Other Chemicals: Alkyl ketene dimer (AKD wax), Quat 188 (Cationic Reagent), General AKD emulsifier 25%, Quat 188 69%,Polymer emulsifier 40%, PolyDADMAC 40%,Wet strenght agent 12.5%/25%, Styrene Acrylic Copolymer, Fixing agent 50%, Poly Aluminium Chloride, Sodium Gluconate Oxidized starch,ect.

Ⅱ Product Properties

The appearance of this product is colorless to pale yellow viscous liquid. It is soluble in water. It has goodhydrolyticstability and high adaptability to PH value changes. It`s safe and non-toxic. Its freezing point is about -2.8℃, specific gravity is about 1.04/cm3  and decomposition temperature is 280-300℃. It`s polymeride AKD maturing agent of high charge density. Emulsion provides strong cationic component promotive and protective agent and promotes curing effect. This product is added directly into the synthesis process of intermediates or added a certain ratio in emulsion. This product can be added more in the papermaking system with heavier anionic trash, as the pulp potential equilibrium to play a dual role of sizing enhancement and forcing ripening.

III. Quality indicators;

Appearance: colorless to faint yellow thick liquid    Solid content: 40±1%

PH value: 4.0~7.0    viscosity (mpa.s, 25℃): 7000-12000

IV. Application:

This product is applied in alkaline sizing system of AKD (Alkyl Ketene Dimer) to restrict largely the hydrolysis and migration aptitude of AKD. [The third generation" AKD is mainly used for the making of multipurpose duplicating paper filled by precipitated calcium carbonate. 60% cationic polymer can adhere to the fiber after the paper containing cationic polymer being reused, by which enhance hydrophobicity of the paper. Added to waste paper deinking agent, its cationic hydrophilic group adheres to ink particles easily, especially for hydrophobic aniline ink. After flotation, the whiteness of pulp increased. This product is also applied as cationic surfactant in pitch control agent for pulping.
