低速剪切混合组分1-6；
依次加入组分7-9，低速剪切混合，高速研磨（如线速度7.0 m/s砂磨）；
低速剪切下，逐步加入有机硅树脂乳液，并依次加入增稠剂调整至适合施工粘度；流平剂根据需要添加；
不建议直接以该有机硅树脂乳液研磨色浆；如需要混合其它有机树脂一起使用，可根据实际情况以有机树脂进行色浆研磨，再混拼入有机硅树脂乳液；使用前有必要对相容性进行测试，pH值是否匹配，该有机硅树脂乳液一般呈现接近中性，可以根据需要以5%氢氧化钾溶液或5%醋酸溶液调整pH值。
推荐干燥条件及特性：室温表干≥45min，230℃ 1.0h 或 250℃ 30min 或 280℃ 15min。

SH-9608/A Silicone Resin Emulsion

Ⅰ. Features

This product is a non-ionic, methyl phenyl silicone resin emulsion designed for heat-resistant industrial coatings. It offers excellent high-temperature resistance, film-forming properties, and air-drying performance, and can be used alone or in combination as a heat-resistant overprint varnish. The varnishes can withstand temperatures up to 350℃ while paints 650℃~700℃. It is infinitely dilutable with water and complies with environmental regulations. Additionally, it shows great compatibility with organic resins and can be used together with them (such as acrylic, polyether, epoxy, etc.), achieving a balance between the high decorative properties of organic resins and heat resistance of silicone resin.

Ⅱ. Technical Data

Item	Index
Appearance	Milky white liquid
Viscosity (25℃, s)	13~30
Solid Content (120℃, 2h, %)	50±2

Ⅲ. Applications

Widely used in industrial heat-resistant applications, such as boilers, heat supply pipelines, electric heaters, furnaces, etc.
Widely used in heat-resistance cookware equipment such as roasters and ovens.

Ⅳ. Packaging and Storage

Standard packaging is 200kg or 50kg plastic drum. The shelf life of this product is 6 months when stored in a cool and dry environment at 5℃~36℃ in unopened packaging. Re-test the product according to the specifications after expiry. It may remain usable if it still meets the requirements.

Ⅴ. How to Use

It is suggested to prepare a waterborne resin-free color paste, and then use it together with this resin emulsion. This product has good room-temperature self-drying properties, providing the workpiece with initial protection and handling ability. However, to achieve superior heat resistance and physical-mechanical properties, it is recommended to fully cure at 200℃~280℃ for 15~60 minutes, preferably at 250℃ for 30 minutes or at 280℃ for 15 minutes.

Ⅵ. Recommended Formulations

For water-based resins such as 9607 and 9608/A, the recommended formulation shown in the table below can be used as a starting point to prepare single-component baking paints.

No.	Component	Wt%	Remarks
1	Deionized water	8.0
2	Coalescing agent	1.5	e.g.dipropylene glycol methyl ether (DPM) or ethylene glycol butyl ether (EB)
3	Substrate wetting agent	0.3	e.g. Evonik (Surfynol 104E)
4	Sodium polyphosphate dispersant aqueous solution, 20% active content	1.2	e.g. ASCC (POLYRON^® N)
5	Waterborne dispersant	2.8	e.g. BYK 190
6	Waterborne defoamer	0.1	e.g. BYK 024, Tego 901, etc.
7	Talc powder	2.4	e.g. Xinda Talc (Talc powder)
8	Mica powder	3.2	e.g. Anhui Grea New Material Technology
9	Copper chromite black, iron manganese black	19.2	e.g. Flow Int’l (PK 3095), LANXESS (Bayferrox 303T)
10	Silicone resin emulsion	60	e.g. Hubei Longsheng Sihai
11	Thickener	1.0	e.g. OMG 0625, or Elementis (BENTONE DE)
12	Leveling agent	0.3	e.g. BYK 381

Mix components of no. 1~6 under low-speed shear.
Add components of no.7~9 sequentially, mix under low-speed shear, and then grind at high speed (e.g., bead milling with a tip speed of 7.0 m/s).
Under low-speed shear, gradually add the silicone resin emulsion, and then add thickener sequentially and adjust to an appropriate application viscosity. Add leveling agent as needed.
It is not suggested to grind the color paste directly with this silicone resin emulsion. Therefore, if this product is used in combination with other organic resins, grind the color paste with organic resins first based on actual conditions, and then blend the mixture with this silicone resin emulsion. It is noted that a compatibility test of the two is needed before use, particularly on whether their pH values match. Generally, pH of this silicone resin emulsion is around 7 and can be adjusted as needed with a 5% potassium hydroxide solution or a 5% acetic acid solution.
Recommended drying condition: surface dry at room temperature for over 45 minutes and fully cure at 230℃ for 1 hour, or 250℃ for 30 minutes, or 280℃ for 15 minutes.
