Introduction

Opaque polymers HIQUE 387 & 388 are Styreneacrylic copolymer emulsions which provide opacity of emulsion paints.

HIQUE 387 & 388 have free of Alkyl Phenol Ethoxylate (APE) derivative surfactant which is known as a kind of mimic estrogen. HIQUE 387 & 388 provide the most efficient dry hiding in interior and exterior coatings.

HIQUE 387 & 388 provide a cost effective way to improve hiding while reducing raw material cost. Main advantage of HIQUE 387 & 388 is as follows.

• Low PVC paints (Gloss, Semi-Gloss, and Sheen)
  . If some parts of titanium dioxide in paint are replaced, it is possible to obtain similar gloss and sheen.
  . When some parts of titanium dioxide are replaced for HIQUE products, it is possible to reduce dirt pick-up by improving tackiness in the surface of the dry paint film.
  . If some parts of titanium dioxide are replaced, it is possible to reduce the prime cost.
  . If some parts of titanium dioxide are replaced, it is possible to obtain the paint film with better hiding.
• Medium PVC and High PVC paints
  . If some parts of titanium dioxide are replaced, it is possible to obtain the paint film with better hiding.
  . If calcined clay is replaced, it is possible to reduce the prime
  . The replacement of calcined clay may lead to the improvement in scrap resistance.
  . For High PVC paints, it is also possible to reduce dirt pick-up with the reduced porosity in the paint film.
• Safety and Handling
  . HIQUE 387 & 388 are slightly irritating to the skin and eyes, and contact with these areas should be avoided. When handling wear impervious rubber gloves and goggles/facemask.
  . For handling/operation where possible contact may occur, a safety shower and eyewash station should be available. Further detailed information can be found in the MSDS documentation.
• Handling/Dosing Equipment
  . It is okay if stainless steel, plastic, rubber, and glass come in contact with HIQUE 387 & 388.
  . However, mild steel, copper, brass, bronze, aluminum, and zinc should be avoided to prevent polymer build-up. As HIQUE 387 & 388 are common emulsion polymers, it is recommended that you use low shear pumps (air diaphragm pumps, mono pumps, etc.) when pumping it.
  . Continuous agitation is not necessary but periodic mixing will prevent slight sedimentation during long term storage. Store in a closed container at 5°C - 40°C.
• Packing
  . The HIQUE that comes in drums or 1 ton IBC tanks contains no biocides.
  . When supplied in bulk, the shipment will contain 0.1% of biocides.
