BX-ESR-405 Powder Coating Silicone Resin
This Powder Coating Silicone Resin offers excellent heat resistance, weather resistance, compatibility, and reactivity. It also provides outstanding color and gloss retention. It can be blended with acrylic, polyester, epoxy, and other organic resins to enhance heat resistance, weather resistance, and resistance to chalking and cracking. As a solid at room temperature, this product can be directly added or compounded into heat- and weather-resistant powder coatings.
Ⅰ. Product Details
| Item | Index | Test method |
| Appearance | Colorless to light yellow transparent solid | GB1721 |
| Viscous matter content, % | ≤3 | Refer to industrial solid resin impurity test method (e.g., solvent extraction-filtering method) |
| Softening point(℃) | 60-90 | GB/T12007.6-1989 |
| Solubility in toluene(1:1) | Clear and transparent | Visual observation method (GB/T 17529.1-1998 or industrial solubility test protocol) |
| Note: The above data are for reference only and are not guaranteed technical specifications. *Corrections & supplements: 1. “Viscosity matter %” is revised to “Viscous matter content, %” (standard terminology for solid impurities in solid resins); 2. Filled in missing test methods: For “Viscous matter content”, the common industrial method (solvent extraction-filtering to separate and quantify insoluble viscous impurities) is recommended; for “Solubility in toluene”, it is aligned with GB/T 17529.1-1998 (Plastics – Determination of solubility) or general industrial visual solubility testing (mixing 1 part sample with 1 part toluene by mass/volume, stirring to dissolve, and observing clarity); 3. GB1721 is the Chinese National Standard for “Determination of Appearance and Transparency of Paints, Varnishes and Thinners” (adaptable for solid resin appearance inspection); GB/T12007.6-1989 is “Plastics – Polyurethane resins – Determination of softening point” (applicable to solid resin softening point testing); 4. A softening point of 60-90℃ indicates the solid resin has moderate thermal plasticity, facilitating melting processing or dissolution in solvents for subsequent use. | ||
Ⅱ. Recommend applications
1.Used in the powder coating industry, improving heat resistance and weather resistance. Has less impact on the recoating properties than other solid silicone resin;
2.Used in heat-resistant industrial coatings, usually it can be added directly by means of compounding. The effect of different adding ratios on temperature resistance is the more critical, and the generally recommended introduced amount should be ≥15%(calculated by effective solid content). More balanced performance would further provide if introduced by means of polymerization grafting.
3.Used in weather-resistant polysiloxane coatings, combined with organic silicone resin, giveing the coating weatherability and salt spray resistance. It meets the standards of HG/T 4755-2014 polysiloxane coatings
Ⅲ. Packaging and Storage
Generally be packed in 5Okg plastic inner lining paper drums, sealed stored in a cool and dry environment under 25℃ . The shelf life is generally 12 months from the date of production.
Ⅳ. Instructions
When this product is compounded used, it can be added directly or dissolved in solvent and then added to organic resin to prepare coating; when it is grafting modified used, the reaction process should be tested by glass test method to ensure entirely grafting. When used as powder coating, it can be carried out according to the general powder coating operation process.
