Thickeners for footwear adhesives

Product Description: is a non-ionic, hydrophobically modified ethylene oxide urethane (HEUR), pseudoplastic thickener (rheological modifier) designed to provide excellent rheological control and performance in water based systems:  outstanding thickening efficiency in the medium shear viscosity region, significantly increase workability and storage stability of the formulation, good colorant stability, excellent leveling and anti-sagging, and a broad application pH range .  It has ultra low odor, and does NOT contain APEO, tin, or organic amine neutralizers.

Uses:  as thickener in water based systems which require storage stability and both good leveling and good anti-sagging.  It is ideal for use in PUD based adhesives for athletic shoes and other footwear manufacturing, particularly suitable for shoe adhesives based on Gaia PUD.

Gaia PUM 604 is a free flow liquid.  It can be added undiluted or pre-diluted with water (1:2; or 1:4), during any stage of the formulation process.  The actual amount required varies with polymers and formulation, and should be based on rheological control profile required for a particular system, normally to be determined by conducting laboratory tests. 

Stability: stable under recommended storage conditions. 

Storage Condition: store in closed original container in cool (5 to 35^oC) and well ventilation areas away from direct sunlight. Do not freeze the product. Do not leave the product uncovered for extended periods of time; immediately tightly close the cap after each material transfer. When stored properly, the resin has a shelf life of at least 12 months from the date of manufacture.

Packing:  20 kg in plastic pails, 200 kg in open plastic drum packed inside with 2 liners of HDPE plastic bags.
