Packaging Specifications: 25 kg/iron drum, 200 kg/iron drum, meeting the industrial - grade packaging requirements for different dosage needs and facilitating storage and transportation.
Core Component: A compound system of fluoropolymer and special surfactant, solvent - free, meeting the requirements of low VOC environmental protection.
Product Performance and Advantages
Efficient Foam - Breaking and Foam - Inhibiting Ability:
For stubborn foam in water - based coatings, adhesives and printing inks, it can quickly penetrate the foam film layer to break it and form a long - term foam - inhibiting barrier in the system. It is especially suitable for water - based systems with high surface tension (such as acrylic emulsion coatings) to solve surface defects such as craters and pinholes caused by foam.
Low Addition Amount and High Cost - Effectiveness:
The recommended addition amount is only 0.05% - 0.3% of the total formula amount, which is much lower than the dosage of traditional defoamers. While reducing costs, it avoids the decline of system performance (such as affecting the gloss or adhesion of the coating) caused by excessive addition.
Wide System Compatibility:
It is compatible with various water - based resins (acrylic, vinyl, polyurethane, etc.) and pigment dispersions, and can play a stable role in colored paints, varnishes and varnishes without causing turbidity of the paint film or affecting the drying speed.
Adaptability to Special Processes:
It is suitable for process scenarios prone to foam generation such as high - speed stirring and spray construction. In the roller coating and brush coating processes of architectural coatings, it can effectively inhibit the generation of dynamic foam and ensure the uniformity of the coating appearance.
Scope of Application and Scenarios
Main Application Fields:
Water - based coatings: Architectural interior and exterior wall coatings, industrial anti - corrosion coatings, wood coatings;
Adhesives: Water - based pressure - sensitive adhesives, woodworking adhesives, packaging adhesives;
Printing inks: Water - based gravure inks, flexographic inks, paper printing inks.
Typical Application Scenarios:
High - gloss wall coatings: Prevent uneven gloss of the paint film caused by foam and improve surface flatness;
Food packaging inks: The solvent - free formula meets the safety standards for food contact materials, ensuring safety while defoaming;
Automotive interior adhesives: Excellent temperature resistance, still maintaining foam - inhibiting effect in high - temperature environments, avoiding the decrease of bonding strength caused by foam.
Usage and Storage Recommendations
Adding Method:
It can be directly added to the system during the production stage. It is recommended to add it in batches under low - speed stirring (to avoid damaging the structure of the defoamer due to high - speed shearing). If used in a high - viscosity system, it can be diluted with a small amount of water before adding.
Compatibility Test:
A small - scale test is required for the first use to verify the compatibility with specific resins, pigments and other additives. Especially in dark paint or systems with high pigment content, the appearance of the paint film after defoaming needs to be tested.
Storage Conditions:
Store in a cool and dry place at 5 - 30℃, avoiding direct sunlight or freezing. After opening, it needs to be sealed and stored to prevent water or impurities from mixing in. The shelf life is 12 months when unopened.
