Hydrophobic Fumed Silica For Aluminum Roll Coating | China Project

Project details

  • Application:  Coatings for Aluminum Roll / Coil 
  • Product Name: A Polyester Resin Coated Aluminum Roll / Coil Factory
  • Location: Shandong Province, China
  • Problem: Company C uses an international brand of hydrophobic fumed silica 972, but the price is high. They want to find a substitute product with good quality and a competitive price.

Coil coating is mostly applied by roller, which requires low viscosity, settle resistance, and good thixotropic performance. Fumed silica can meet all these needs.

  • A Polyester Resin Coated Aluminum Roll

Solution

Coil coating is generally divided into PE system, epoxy system, and acrylic system. PE and acrylic products take up 90%, of which PE is 60%.

  • Dimethyldichlorosilane/DDS-treated fumed silica applies well for polyester resin coatings, such as HIFULL HB-151 or HB-152.
  • Hexamethyldisilazane/ HMDS-treated fumed silica applies well for acrylic coatings, such as HIFULL HB-620.
  • Polydimethylsiloxane /PDMS-treated fumed silica applies well for epoxy coatings, such as HIFULL HB-139.

Client Feedback

Company C tested HIFULL HB-151 to replace the international one. Results show that thixotropic property is not as good, but over-all performance good enough to replace. When rolling the color, HIFULL HB-151 one is slightly white in color-intensity, but company C is fine with that. HIFULL HB-151 hydrophobic fumed silica is a cost-effective choice with quality.
