- Materials of Construction
Cross-linked polyethylene, fiberglass, stainless steel or lined steel are the preferred materials of construction for bulk tanks.; Avoid natural rubber and Buna-N gaskets as these materials swell when placed in contact with neat polymer.; Unlined mild steel, black iron, galvanized steel, copper or brass are not recommended in any part of the feed system.; Stainless steel, Viton or Teflon are the best choices for pump heads.; For feed lines, polyethylene, PVC or reinforced Tygon tubing is recommended.

- Preparation and Feeding Information
PWT 3230 is a single component emulsion polymer that must be pre-diluted in water before use.; In most cases, this product should not be applied neat.; One method for dilution is adding the neat polymer into the vortex of a mixed tank at a concentration between 0.25 - 1.0% polymer (0.5% is optimum)by weight.; The polymer can also be injected through a number of commercially available systems that provide in-line mechanical mixing.; Polymer solutions should be aged for 30-60 minutes prior to use for best results. Solution shelf life is 8-16 hours.
- Storage, Stability and Handling Information
Suggested in-plant storage life is one year in unopened drums.; For best results, store at 50-80°F.; Bulk tanks should be mixed by periodically recirculating the contents bottom to top.; Bulk tanks can also be fitted with an agitator type mixer that reaches the bottom 2 feet of the tank.; Do not allow emulsion polymers to freeze.; Should freezing occur, allow the product to thaw thoroughly in a heated area and mix well before attempting to use it.; For spills of PWT 3230, sprinkle salt, vermiculite or equivalent absorbent over the spill area and sweep the material into approved chemical disposal containers.; Do not spray water onto a spill because the resulting gel is very difficult to clean up.
