DRY STRENGTH RESIN GDSR1521

DRY STRENGTH RESIN GDSR1521 is amphoteric polyacrylamide with
excellent dry strength performance. The product is designed to improve
paper/paperboard strength as well as drainage, and retention of fiber, fine and filler.

Properties
   Appearance:                           Amber liquid
   Ionicity:                                   Amphoteric
   Total solids (%):                     ≥ 20.0
   pH value:                                 2.5-4.5
   Viscosity (mPa.s, 25°C):         7,000 ± 3,000
   Specific gravity (25°C):           1.07 ± 0.01
   Shelf life (months):                    6  (5-25°C, avoid direct sunlight)

Advantage
1. Very high effective for increasing filler or ash in paper without side effect.
2. Effective in improvement of the retention of fine and filler, and the drainage
of the wire section in wide pH range.
3. Improved sheet strength in wide pH range.
4. Improved retention of sizing agents, and furthermore promoted sizing.
5. Effective even in strongly anionic and high electro-conductive conditions.
6. Easy to recover paper broke.

Application
GDSR1521 should be diluted more than 10 times before addition to pulp slurry.
Use of continuous dilution unit for high viscosity solution will be recommended.

Handling
GDSR1521  is stable for 6 months at 5-25°C. Please avoid direct sunlight, high
temperature or freezing. It is not recommended to store the diluted solution of
GDSR1521 for a long time. Diluted solution will lose its efficiency in a short period of
time. Do not mix with other chemicals directly.

Packaging
IBC container (1 MT), flexibag
