Application Fields
- Solvent - based original automotive coatings: It can effectively eliminate foam generated during coating production and painting, avoid defects such as bubbles and pinholes, ensure a smooth and flat coating surface, and improve the aesthetics and durability of automotive paint surfaces.
- Other solvent - based systems: Such as industrial protective coatings, wood coatings and other solvent - based coating systems, it can also play a defoaming role to ensure the construction performance and final quality of coatings.
Performance Characteristics
- Efficient defoaming: In polar solvent - based systems, it can quickly and effectively eliminate generated foam and inhibit foam regeneration for a long time, ensuring the smooth progress of coating production and construction.
- Excellent compatibility: It has good compatibility with various resins, pigments, additives and other components in solvent - based systems, and will not cause surface defects such as craters and fisheyes. Especially in clear coating systems, it will not reduce the transparency of clear coatings and can maintain the original gloss and clarity of the coating.
- System adaptability: Although the defoaming effect is relatively weak in non - polar systems, it performs well in polar systems and is suitable for a variety of solvent - based coating formulations with different properties, providing more flexibility for formulation design.
- Good stability: Under normal storage conditions, the product has good physical and chemical stability, and is not prone to problems such as delamination, precipitation or deterioration, and can maintain defoaming performance for a long time.
Recommended Dosage
It generally accounts for 0.1% - 1% of the total formula dosage. The specific dosage needs to be adjusted according to the actual situation such as the severity of foam in the coating system, solvent type and formula complexity. For example, for systems with serious foam problems, the dosage can be appropriately increased; for relatively stable systems that are not prone to foam, the dosage can be appropriately reduced.
Usage Method
- Adding stage: It can be added in the grinding stage and paint mixing stage of coating production. Adding in the grinding stage helps inhibit foam generation during pigment dispersion; adding in the paint mixing stage can eliminate foam formed by air introduced during the mixing process.
- Stirring and dispersion: After adding, it needs to be fully stirred to make the defoamer evenly dispersed in the coating system to ensure the full play of the defoaming effect.
Storage and Transportation Conditions
- Transportation: Transport according to general chemical transportation requirements. During transportation, collision, inversion and exposure to the sun should be avoided to prevent packaging damage and affect product performance.
- Storage: It should be stored in a cool, dry and well - ventilated warehouse, avoiding direct sunlight and high - temperature environments. The recommended storage temperature is controlled at 5 - 35°C. Under the specified storage conditions, the product storage period is generally 24 months.
Safety Information
Avoid direct contact with skin and eyes during use. In case of accidental contact, rinse immediately with plenty of water and seek medical treatment in time. Use in a well - ventilated environment to avoid inhaling the gas volatilized from the product.
