In the applications of protective face masks, car lamps and optical lenses and other transparent plastic products, the fogging phenomenon caused by temperature differences has long affected the safety of product use and visual clarity. Our company's product, two-component anti-fog agent 7000 (6000), as a two-component thermosetting anti-fog coating designed specifically for polycarbonate (PC) substrates, with its precise formulation design and professional construction compatibility, has demonstrated reliable anti-fog application value in helmet masks, car lamps, protective glasses and optical panels, providing a professional-level coating solution for PC transparent products' anti-fog treatment.


I. Core Characteristics and Physical and Chemical Indicators of the Product


The two-component anti-fog agent 7000 (6000) is a colorless transparent to slightly yellow liquid, belonging to a two-component product system, and needs to be used in combination with our company's dedicated curing agent. At 20 degrees Celsius, the -4 cup viscosity is 13 to 15 seconds, the specific gravity is not less than 0.90, and the solid content is 11 ± 1 percent. The recommended ratio of the main agent to the curing agent is 4:1. This product contains flammable solvents, and during construction, fire safety must be noted, and transportation management should be carried out in accordance with hazardous goods requirements. The product is available in two packaging specifications: 4 kilograms plastic drums and 18 kilograms iron drums. Customization can also be provided according to customer requirements. Under unopened conditions, the shelf life is 6 months. After opening, it is recommended to use it within 1 month. It should be stored in an environment of 30 degrees Celsius or below, avoiding direct sunlight.


II. Construction Process and Environmental Control Requirements


The anti-fog effect of this product is closely related to the construction process and has clear requirements for the spraying environment. The indoor temperature should be controlled at 20 to 30 degrees Celsius, and the environmental humidity should be lower than 80% RH. Pre-treatment before spraying is a key process to ensure the quality of the coating, and methanol, ethanol or IPA type solvents should be used to thoroughly remove the release agent and grease components on the lamp cover surface, and the surface dust and static electricity should be cleaned with a hair dryer. It is recommended to use a low-fogging pressure spray gun, with a spraying distance of 15 to 20 centimeters, and the spray volume should be controlled at 70 to 150 milliliters per minute. The recommended coating thickness is 2 to 5 microns, too thin may cause surface roughness and spots, and too thick may result in appearance defects such as runnability and dripping. PC substrates can be cured at 120 degrees Celsius for 15 to 25 minutes to complete the coating curing.


III. Application Areas


The two-component anti-fog agent 7000 (6000) is suitable for anti-fog coating of PC (polycarbonate) substrates and can play an important role in the following scenarios, specifically including:


1. Personal safety protection field. It is suitable for anti-fog treatment of motorcycle helmet masks, safety protection masks, goggles, etc., ensuring clear vision of users in temperature change environments.


2. Car lighting and traffic facilities. It is suitable for anti-fog coating of car lamps, instrument panel transparent panels and various traffic facility transparent windows.


3. Optical and electronic equipment. It is suitable for anti-fog protection of optical lenses, instrument panel view windows and electronic equipment display screens, etc., of PC transparent components.


4. Quality Assurance and Construction Tips


The product two-component anti-fog agent 7000 (6000) has established a strict quality control system during production, implementing full-process detection of key indicators such as product appearance, viscosity, specific gravity and solid content to ensure consistency and reliability between batches. During construction, the cleanliness of the surface of the sprayed object has a significant impact on the coating effect. Dust in the air and dust carried by the human body may cause poor coating appearance. It is recommended to conduct construction in a clean environment with a higher cleanliness level and wear special spraying clothing. This product is a two-component system, and it must be strictly mixed in a 4:1 ratio, and the mixture should be used up within the applicable period. With the continuous increase in the requirements for anti-fog performance of transparent plastic products in industries such as safety protection, automotive lighting and optical electronics, this product, thanks to its precise two-component ratio design, professional construction compatibility, and targeted optimization for PC substrates, is becoming an important product option in the field of anti-fog coating for PC transparent products. It provides strong coating technology support for enhancing the safety and visual quality of related products.
