PTC-A19 is a standard starch-stabilized, alkyl ketene dimer (AKD) size dispersion, for the sizing of paper and board under alkaline conditions. All products have a low ketone content, and display low agglomeration. At normal dosage levels, PTC-A19 products do not significantly quench optical brightening agents (OBAs, FWAs) so they are particularly suitable for use when whiteness is important, such as in uncoated fine papers.

PTC-A19 AKD Emulsion which is a reactive size and is a highly efficient sizing chemical. It is specifically designed to enhance drainage and optimize sizing efficient in most paper making systems. We manufacture different grades of AKD Emulsion different types of papers. Our emulsion are uniquely formulated to work effectively paper industry. These Emulsion provides excellent resistance to a wide variety of penetrates and react directly with cellulose ro provide sizing. In India, we are one of the leading manufactures and exporter of AKD Wax Emulsion. We manufactures various grades of AKD Emulsion for Different types of paper and specifications for one of grade is as follows.

Chemical Nature

• Alkyl Ketene Dimer
• Physical form: White Emulsion
• Lonic charge: Cationic

Application:

The cationic starch which stabilize PTC-A19 has excellent substantivity for papermaking fibres under neutral and alkaline conditions, ensuring that the size is well retained. During the drying of the paper, the AKD wax melt and spreads over the surface of the fibres, where it undergoes an esterification reaction. The reacted AKD is thus bonded to the fibres with the hydrophobic portions of the molecule oriented away from the fibre surface, giving the sizing effect.

Benefits:

Provides economical sizing performance in most grades of paper and paperboard Excellent substantively due to the stabilizing cationic starch

• No significant quenching of OBA/FWA
• Good curing rates
• Works at pH range of 7.1 - 7.5
• Low foaming characteristics.
• Compatible with retention & drainage aid systems, and especially the advanced microparticle technologies Added to the thick stock at a point of high shear for optimum distribution in the stock.

P-SIZEX-30 is usually applied in the size press/metering size press in combination with starch, but it can also simply be diluted with water. It can be added in batches or continuously, the latter method being more versatile in that it enables levels of addition to be adjusted more quickly as circumstances demand.

The paper does not necessarily have to be sized at the wet end before P-SIZEX-30 is applied, but this can be an effective means of controlling the extent to which the size solution is able to penetrate.

The recommended concentration 5 g/l and 20 g/l of P-SIZEX-30 are required for hard-sized paper, if it is applied on size press in water, depending on factors such as whether any size is added at the wet end, etc. This can be combined with starch in concentrations between 20 g/L and 130 g/L.

Technical Specification

• It is compatible with the nonionic and cationic auxiliaries that are applied to paper in the size press/metering size press.
• P-SIZEX-30 has no detrimental effects on brightness, and it does not impair the fluorescent activity of optical brighteners.

Compatibility

P-SIZEX-30 can be combined with starch, direct dyes, acid dyes, fluorescent brighteners and other anionic and nonionic substances, but it is always advisable to take the precaution of testing its compatibility in advance.

The cationic starch which stabilizes PTSC- A22 has excellent substantively for papermaking fibers under neutral and alkaline conditions, ensuring that the size is well retained. During the drying of the paper, the AKD wax melts and spreads over the surface of the fibers, where it undergoes an esterification reaction. The reacted AKD is thus bonded to the fibers with the hydrophobic portions of the molecule orientated away from the fiber surface, giving the sizing effect.
