JN BA-3132aSurface Sizing Agent

v  Function

JNBA-3132a Surface Sizing Agent is a synthetic copolymer of high molecularcationic emulsifier and styrene ester monomer. It mixes well with starch andprovides the starch coating with excellent cross-linking strength and hydrophobicproperty. It’s featured by low consumption, free odor, low foaming, longfoaminhibitionperiod and excellent film forming, and it can significantlyimprove the water resistance capability and ring pressure strength ofcorrugated paper and cardboard paper. It is a sufficient substitute for internalsizing agent and has no maturation period.It is applicable to various types ofsurface sizing machines

v  Use

Whenused together with oxidized starch, the amount of JN BA-3132aSurface Sizing Agentrequired for a ton of paper is 1 to 3 KG. With the appropriate amount of aluminumsulfate added in the gelatinized starch solution, the positive charge will beincreased to neutralize the interfering negative ion for better sizing effect(it is suggested that the pH value of the starch solution shall be controlledbetween 3.0 and 4.0). Keep adding the product in the suction side of starchadding pump with a metering pump for surface sizing; or slowly add it to thestarch storage tank while stirring until the mixture becomes homogenious forsurface sizing. It is better to keep the temperature of the sizing solutionbetween 60 and 80 as lower temperature might strengthen the viscosityandaffect the absorption and penetration of the starch solution.

v  Cautions

Theproduct is non-dangerous goods and can be transported by regular means. Itshould be stored in a cool and shady place(525) and be protected from freezing and sun exposure.

v Packing

200kg1000kg plastic drum, or according to customer requirements.
