From low-speed machine to high-speed machine, normal paper to sized paper, low-weight paper to high-intensity paper, environmentally-irresponsible additives to environmentally-friendly additives, the method of conventional paste making can no longer adapt to the rapid development of the corrugated cardboard industry. It cannot satisfy the higher and higher environmental responsibility of the clients.

Unmodified starch paste contains large amounts of hydroxyl, which will easily absorb the moisture in the environment, resulting in a poor water resistance and higher accessibility to moisture. For high-weight paper, sized paper and special paper, the problems of adhesion, pit exposure, ward and moisture resistance would remain unsolved with the normal additives.

DF-09 starch paste enhancer is a special chemical. Its molecular chain contains large amounts of hydroxyl, which will have a cross-linking reaction in contact with the hydroxyl on the starch chain to form the curing phase. Hence it can improve the strength and moisture resistance of the cardboard effectively. 

Permeability:

Some active groups in the DF-09 could penetrate the AKD wax or styrene polymer coating on paper fiber surface, thus to decrease the contact angle between adhesive layer and paper fiber, enhancing the permeability of starch paste, improving the adhesion strength hence lowering the adhesion rejection rate.

Water Retention:

DF-09 offers starch paste excellent water retention, ensuring the moisture, diffusion, absorption and curing on the surface of paper fiber, within 0.1~1 second.

 Thermosetting:

DF-09 is a thermosetting resin, it contains large amounts of active groups which is able to have 3-D cross-linking with starch hydroxyl. After curing, the adhesive layer will get harder, hence improve the the cardboard hardness, horizontal pressure and vertical pressure. 

Moisture Resistance:

DF-90 has improved the dry strength and wet strength significantly between adhesive layers, therefore the cardboard have much better moisture proof function and moisture resistance. It is sufficient to cope with the long-term storage and the challenges of various extreme environments such as refrigeration, sea transportation, etc. (The finished cardboard can be soaked in water for 300 hours without tacking, the adhesive strength will remain unchanged after natural drying). 

Foam Control:

DF-09 has good foam inhibiting and suppressing functions, so that it can prevent the 'fake adhesion' of cardboard effectively resulting from excessive foam of starch paste.

 Antiseptic Control :

Under standard conditions, the antiseptic ingredients of DF-09 can prevent the starch paste from corrosion and metamorphism for a week's time. 

Environmental Protection:

DF-09 always strictly implements the 'RoHS Directive' and '94/62/EC' which is directly related to the law of packaging material. Guarantee: There is no formaldehyde pollution in the process of paste making, adhesion of corrugated cardboard and the final products of cardboard (cartons).
