The Cleaning Solution EE-3310 and EE-3320, exclusively available in Thailand, are high-performance cleaning agents lauded for their quick drying, minimal material damage, and superior cleaning efficacy, making them recommended alternatives to Ether, Acetone, and Thinner for hand wiping. EE-3310 is a finishing cleaning solution specifically formulated for lenses, prisms, glass products, and precision engineering parts, extensively utilized in the optics industry for production, repair, and inspection. Its technical specifications include a composition of silicone solvent and ethanol, a colorless and clear appearance with an alcohol odor, a boiling point of 78.3°C, specific gravity of 0.77, viscosity of 0.86 mm²/s, and a flash point of -1°C. It is classified under Japan's Fire Service Act as Class 4, Class 1 Petroleum/Non-aqueous liquid. Conversely, EE-3320 is designed for a milder impact on plastics than EE-3310, making it ideal for acrylic or plastic surfaces where alcohol-induced cracking is a concern. This variant contains silicone solvent, is colorless and clear with a slight odor, and features a boiling point of 100°C, specific gravity of 0.76, viscosity of 0.65 mm²/s, and a flash point of -1°C. It also falls under the same Fire Service Act classification. Both solutions are widely used for hand wiping optical parts, monitor panels, and for daily maintenance and inspection of optical and OA components in process line fields. They are typically supplied in 1kg metal cans or 13kg oil cans. Users must handle these highly volatile and flammable products with protective gear due to their silicone content and potential for irritation, as they are strictly for industrial use and not for medical implants.
