Supply of solid silicone resin powder coating of the same type as Dow Corning

Description :

　　High temperature solid organic silicon resin 7033 Dow Corning's same silicone resin selected from Sihai Chemical SH-1068 solid organic silicon intermediate

　　1、 Performance and Application

　　This product is an intermediate of methyl basic silicone resin containing silicone groups, which has good compatibility and high reactivity. It can be compounded with acrylic acid, polyester, epoxy and participate in crosslinking curing reactions; Introducing organic silicon intermediates through compounding or polymerization modification can significantly improve the weather resistance of organic resins, especially anti powdering and anti cracking, endowing outdoor industrial paints with light and color retention properties; Introducing organic silicon intermediates through compounding or polymerization modification can significantly improve the heat resistance of organic resins. For example, the introduction of 30% organic silicon intermediates can increase the sustained heat resistance of organic resins to 300-350 ℃; The organic silicon resin intermediate is sold in solid form and can be directly or compounded for use in heat-resistant and weather resistant powder coatings;

　　2、 Main technical indicators of solid organic silicon resin

　　Appearance: Colorless to pale yellow, transparent, solid GB1721

　　Volatile matter (150 ℃, 1h) ≤ 3%

　　Softening point (℃) 35-45 Internal testing method

　　3、 Recommended application of solid silicone resin 7033

　　1. Widely used in the powder coating industry, it participates in the cross-linking and curing reactions of polyester, epoxy, and acrylic acid, improving the heat resistance and weather resistance of coatings, and has a smaller impact on the recoating performance of coatings compared to other solid silicone resins;

　　2. Widely used in heat-resistant industrial coatings, it can generally be directly added through compounding. The influence of different addition ratios on temperature resistance performance is crucial, and it is generally recommended to introduce an amount of ≥ 15% (calculated based on effective solid content); If introduced through polymerization grafting, it can further provide more balanced performance;

　　3. Widely used weather resistant polysiloxane coatings, combined with organic resins, endow the coating with both weather resistance and salt spray resistance, in compliance with the HG/T 4755-2014 Polysiloxane Coatings standard;

　　4、 Packaging and storage of solid silicone resin 7033

　　Generally packaged in 50kg, 25kg plastic lined paper drums, sealed and stored in a cool and dry environment at 5-25 ℃, with a corresponding shelf life of 12 months from the date of production.

　　5、 Construction reference for solid silicone resin 7033

　　When using this product in combination, it can be directly added or dissolved in a solvent before being added to the organic resin to prepare the coating; When grafting modification is used, the reaction process should be tested using glass sheet testing method to ensure sufficient grafting; When used as a powder coating, it can be operated according to the general powder coating process.
