CAREGUARD (CONC). | Oil and Water Repellent

Careguard (Conc..) is a water and oil-repelling fluoropolymer based on C8 chemistry. It confers highly durable water and oil repellency on various substrates viz., polyester,cotton, wool fibres and their blends. It can be applied by padding, foam and by spray technique. They give very good results on polyproplyene and polyester nonwoven fabrics also.

• Pick-up : 65-70%
  
• Bath pH : 4.0 - 4.5
  
• Drying : 100 - 120 deg.C
  
• Curing : 150 deg.C,5 min. OR 160 deg.C,3 min. OR 170 deg.C, 1 min.
  

SUGGESTED RECIPES:

For all substrates :

• Careguard (Conc.) : 25-70
  
• Acetic Acid : 0.5 g/l
  
• IPA : 5 g/l
  

*Concentration of Careguard (Conc.) to be taken on the basis of durability requirement.

1. It is recommended to pre-wash the substrate to be treated with 1 g/l Saragen-DAM at 80-85 deg.C for 20-30 min. to remove traces of residual impurities to get excellent results.
2. After padding and drying, if the fabric is kept overnight before curing, results will be further improved.
3. Water-oil repellent finish can be combined with resin finish using 30g/l Saralink-ULF + 6g/l MgCl2 + 20g/l Saralube-2975.

Sequence of addition :

• Prepare bath with all ingredients including Saralink-ULF, MgCl2 in water containing Acetic acid.
• Stir continuously and add Careguard (Conc.) as the final ingredient.

Precautions :

• Avoid high speed and continuous stirring.
  
• Avoid silicone based softeners in the finishing recipe.
  

Precautions

Storage: Store in cool, ventilated shed away from heat and direct sunlight. Storage temperature should not exceed 35 deg C.Close lids firmly to avoid contact with air and moisture.
