BX-ESR-403 Methylphenyl polysiloxane resin

DOCUMENTS

BX-ESR-403 is a reactive, Solvent-free Silicone Resin featuring a narrow molecular weight distribution. This methyl/phenyl alkoxy functional polysiloxane is designed to significantly improve the high-temperature and weather resistance of resins like acrylic, polyester, and epoxy, potentially increasing continuous heat resistance to 350°C.

Ⅰ. Product Features

  1. Solvent-free Silicone Resin Efficiency: A reactive, solvent-free polysiloxane with a narrow molecular weight distribution for cleaner, high-performance formulations.
  2. Thermal Performance Enhancement: Introducing 30% of this silicone intermediate can improve the continuous heat resistance of organic resins to 300-350°C.
  3. Broad Compatibility: Suitable for introducing compatible silicone components into acrylic acid, polyester, and epoxy resins.

Ⅲ. Primary Applications

  1. Resin Modification: Enhancing weather and heat resistance for acrylic, polyester, and epoxy base materials.
  2. Specialty Coatings: Production of high-performance finished paints using pigment fillers or color pastes.

Ⅳ. Packaging and Storage

Solvent-free Silicone Resin is packed in 200 kg plastic drum, stored in a cool and dry place, avoid direct sunlight, avoid acid and alkali contact. This product belongs to non-dangerous goods

Ⅴ. Instructions

1.It is generally recommended to use the pigment filler and a part of the resin to prepare the paste, then add the remaining silicone resin to produce finished paint. You can also mix the resin-free color paste into the resin to adjust finished paint.
2. Xylene and other solvents not containing hydroxyl can be chosen as diluent.
