In the process of continuous upgrading of household appliances, cookware, automobiles and industrial equipment towards higher temperature resistance and environmental friendliness, the selection of the base material for water-based high-temperature resistant coatings has become a core factor determining the performance and environmental friendliness of the coatings. Although traditional solvent-based silicone resins can provide excellent heat resistance, their volatile organic compound emissions conflict with the increasingly strict environmental regulations. Our company has launched the product water-based high-temperature resistant silicone resin emulsion 68604, which is a non-ionic water-based silicone resin emulsion. With its good water dilution property, excellent film-forming property, and the ability to be formulated into high-temperature resistant coatings of 200 to 1000 degrees Celsius by combining with heat-stable pigments and fillers, it demonstrates significant application value in numerous fields such as household appliances and cookware, automotive exhaust pipes, outdoor metal corrosion protection, and electrical insulation, providing environmentally friendly and high-performance coating base material solutions for customers in various industries.

Its good water dilution property enables easy adjustment of the construction viscosity, and the curing conditions are flexible. It can cure at 200 to 280 degrees Celsius, 10 to 60 minutes, with the optimal curing time being 220 degrees Celsius for 30 minutes or 280 degrees Celsius for 10 minutes.


III. Wide Application Areas


The water-based high-temperature resistant silicone resin emulsion 68604, with its multi-functional performance combination, can play an important role in the following key application areas:


1. High-temperature resistant coatings for household appliances and cookware. The product is suitable for high-temperature water-based coatings for household appliances and cookware such as oven, stove, frying pan, non-stick pan, fireplace, and fireplace, providing good thermal stability and appearance decoration for the products.


2. High-temperature protection for automotive and industrial components. It is suitable for high-temperature water-based anti-corrosion coatings for metal components in automotive exhaust pipes, engines, ovens, kilns, chimneys, etc., providing long-term heat protection and corrosion resistance.


3. Outdoor metal corrosion protection coatings. It can be used as the base material for outdoor metal water-based corrosion-resistant coatings, with excellent weather resistance and salt spray resistance, suitable for long-term protection of outdoor metal components such as building steel structures, bridges, and pipelines.


4. Special function coating base materials. The product is the most suitable base material for preparing high-temperature water-based insulation, fireproof, heavy-duty anti-corrosion, thermal conductivity, and insulation coatings. It is also widely used in water-based insulation coatings for household appliances (such as non-stick pan coatings), electronic and electrical components, and mechanical products.


IV. Operating Procedures and Precautions


Suggestions for preparing the paint: First, prepare water-based resin-free color paste, and then use it in combination with water-based silicone resin emulsion; evenly disperse all components until uniform, at a speed of 1000 to 1500 revolutions per minute, for 20 to 30 minutes, and adjust to the appropriate viscosity. Package with a 200-mesh filter bag. You can add deionized water according to your needs to adjust the solid content, and adjust the appropriate pigment-binder ratio as needed. It is recommended to control the dry film thickness of a single spray at 35 to 50 micrometers. When using for the first time, slowly warm up to a high-temperature environment to complete the secondary sintering of the paint film. The paint will settle over time, so before construction, thoroughly mix and stir evenly. Add 5% to 10% of deionized water as needed for dilution.


V. Packaging Specifications and Storage Conditions


The product water-based high-temperature resistant silicone resin emulsion 68604 is packaged in 50-kilogram plastic drums. This product should be stored in a ventilated and cool place above 0 degrees Celsius, not exceeding 40 degrees Celsius, and transported as a non-hazardous product. Store in a sealed container, with a shelf life of 12 months.


VI. Quality Assurance and Application Value


The water-based high-temperature resistant silicone resin emulsion 68604 has established a strict quality control system during production. It conducts full-process testing on key indicators such as appearance, pH value, solid content, viscosity, and density to ensure consistency and reliability between batches. As industries such as home appliances, automobiles, industrial protection, and special coatings continue to develop towards water-based and environmentally friendly directions, the demand for water-based silicone resin bases with both high-temperature resistance and convenient application is steadily increasing. This product, with its wide temperature range of 200 to 1000 degrees Celsius for heat resistance, non-ionic water-based system's environmental characteristics, and flexible curing conditions, is becoming an important base material option in the high-temperature water-based coatings field, providing strong product support for promoting the transition from solvent-based to water-based in related industries.
