Epoxy polysiloxane topcoat, as a high-performance coating, occupies an important position in the field of metal surface protection due to its excellent weather resistance and high glossiness. However, the performance of this coating largely depends on the choice of hardener in its formulation. Therefore, innovation and optimization of hardeners have become the key to improving the performance of epoxy polysiloxane topcoats.
As a leading global chemical enterprise, Wacker Chemie has been committed to the research and production of high-performance coatings. At this exhibition, Wacker Chemie launched its star product - SILRES ®  Upgraded version of HP 2000 LV silicone hardener. The launch of this new product marks an important step for Wacker Chemicals in the field of epoxy polysiloxane topcoats.

SILRES ®  HP 2000 LV silicone resin hardener is known for its low volatility (LV), with significantly reduced volatile compound content. This characteristic enables the hardener to formulate safer and easier to apply metal coatings. At the same time, the hardener continues the excellent performance of its predecessor and can be directly used in existing formulations without significant adjustments.
Using SILRES ®  The coating formulated with HP 2000 LV silicone resin hardener can maintain its luster even after years of sun exposure and weathering. Combined with suitable primers, this type of coating can provide excellent corrosion protection, making it an ideal choice for ships, bridges, and industrial facilities. In addition, the use of this hardener in topcoats can create a dual coating system, which is more cost-effective compared to traditional three coating systems.
In addition to high efficiency, the new silicone resin hardener also has more advantages. The content of cyclic methylsiloxane and methoxymethylsilane is less than 0.1%, which eliminates the chemical labeling restrictions for similar hardeners and broadens the application scenarios. Higher product purity also enhances occupational health and safety, providing dual protection for coating manufacturers and construction companies.
This innovative measure by Wacker Chemie not only enhances the performance and safety of epoxy polysiloxane topcoats, but also brings new development opportunities to the coatings industry. With the increasingly strict environmental regulations and constantly changing consumer demands, high-performance and low volatility coatings will become the mainstream trend in the market. SILRES from Wacker Chemie ®  The HP 2000 LV silicone resin hardener will undoubtedly play an important role in this trend.
In the future, Wacker Chemie will continue to focus on the research and production of high-performance coatings, continuously launching innovative products and technologies to meet the diverse needs of the market. At the same time, the company will strengthen cooperation and communication with partners to jointly promote the sustainable development and progress of the coatings industry.
