1.U-301
Properties
Appearance : Pale-yellow liquid
Charge : Anion
Active : 38.0 กพ 2.0 %
Viscosity : 500 cps Max.
pH : 9.0 กพ 1.0 (pH Paper)
Solubility : Easily dissolved in water

Characteristics
As an anionic resin of urea-formaldehyde type, it is widely used in paper making process such as corrugated board base paper, tissue paper, water-resistant liner paper, etc. Because it is easily dissolved in cold water, its treatment is very convenient and it gives excellent waterresistance to paper. It also improves strength and water-resistance of paper when used with starch and anionic chemical in size press coating.

2.U-303
Properties
Appearance : Pale-yellow liquid
Charge : Cation
Active : 36.0 กพ2.0 %
Viscosity : 50 cps Min.
pH : 6.0 กพ1.0 (pH Paper)
Solubility : Easily dissolved in water

Characteristics
As a cationic resin of urea-formaldehyde type, it is widely used in paper making process such as corrugated board base paper, tissue paper, water-resistant liner paper, etc. It has excellent self-fixing ability on anionically charged fibers and it is easily dissolved in water without affecting by the water quality. It needs less alum quantity than anionic resins and gives strong water-resistance to paper.

3.BEST-7
Properties
Appearance : Amber liquid
Charge : Cation
Active : 12.5 กพ 1.0 %
Viscosity : 200 cps Max.
pH : 4.0 กพ 1.0
Solubility : Easily dissolved in water

Characteristics
As a cationic poly-(aminoamide)-epichlorohydrin(PAE) resin of non formaldehyde type, it can be used in various paper making process as urea-formaldehyde and melamine-formaldehyde resin. Because of its nontoxic property. it can be used for the sanitary paper and the paper for food contact.
Especially, it is available at a wide pH range(4~9) and improves the size degree. It can greatly improve the wet strength when used with anionic resin.
