         the mixing acrylic binder solution to be consumed within a day(24hous).

 FIXER  MCL-400

Top 

  • Cross-linking agent at low temperature for Fluorocarbon resins
  • FIXER MCL-400 is a newly developed cross-linking agent to meet the quality improvement in the market like higher durability for Water and Oil repellent finishing with Fluorescent carbon resin under only drying and non-curing process.
 Properties:
 Appearance  Clear viscous liquid
 Main component  Polyiosyanate
 Viscosity  2,000 ~ 3,000mPa.s(cps)
 Ionic  Non Ionic
 Features:
  • FIXER MCL-400 is a non-block type isocyanate and it starts cross-linking function to Fluorocarbon resin at low temperature like room temperature and therefore, curing/baking treatment is not required.
  • FIXER MCL-400 is giving the outstanding Washing and Dry Cleaning fastness to Water/Oil repellent finishing with Fluorocarbon resins. 
  • FIXER MCL-400 does not create Yellowing problem.
  • FIXER MCL-400 is non-formaldehyde type cross-linking agent and also, it is no harm to human skin.
 Application
  • 0.1% to 0.5%(from 1gm/L to 5gm/L) against on weight of padding solution with Fluorocarbon resins for 100% cotton or their blended material.  In case of Synthetic fabrics like 100%  polyester or 100% Nylon, the dosage can be reduced to 1/2 ~ 1/3 of the above. 

    FIXER MCL-400 to be diluted under 1:1 ratio with water and add into padding solution.

    Caution:
  • FIX MCL-400 starts cross-linking function at room temperature and it is recommendable to add FIXER MCL-400 just before the padding process and consume the mixed solution as soon as possible like within 4 hours.
  • When processing takes time over 4 hours after preparation of padding solution, half the quantity of initial dosage of FIXER MCL-400 to be added into padding bath in every 4 hours. 
  • FIXER MCL-400 reacts to moisture in the air and so, the cap of packing or lid on the can to be closed tightly. Handle to be care with care putting on rubber gloves, protection mask and goggles.
 EVALUATION:
 Subject  Durability test on water repellent finishing
 Material  100% cotton woven fabric
 Padding condition  Under 1 Dip/1 Nip at Pick-up 73%
 After treatment  a) Only drying at 90íC x 3min.
 b) Drying at 90íC x 3min and Curing at 180íC x 1min.
 Condition of washing test  40íC with Synthetic detergent 2gm/L
 for 15min. x 1, 2, 4, 6, 8, 10 and 12 times.
