I. Basic Information

Product Type: Defoamer
Brand & Model: Foamaster 111 (Mo211)
Core Ingredient: Mineral Oil, processed through advanced deep hydrogenation refining technology. It has high purity, stable molecular structure, excellent foam-breaking efficiency and long-term foam-inhibiting performance, and is especially suitable for water-based systems with high filler content.
Packaging Specification: 180 kg/blue iron drum. Packed in anti-corrosion galvanized iron drums, the drum body is equipped with double sealing covers and anti-theft rings, which can effectively prevent leakage or pollution during transportation and meet the needs of industrial bulk procurement and storage.

II. Core Features

Special Adaptability to High-Filler SystemsDesigned for water-based coatings, inks and adhesive systems with high content of calcium carbonate, kaolin, titanium dioxide and other fillers. It can overcome the problem of defoamer failure caused by filler surface adsorption, and still maintain a stable defoaming effect in systems with filler content ≥ 30%, avoiding rough coating or blurred printing dots caused by residual foam.
Dual Mechanism of Efficient Foam Breaking and Anti-Filler Interference

Rapid Foam Breaking: Mineral oil molecules can quickly penetrate the foam film wall and achieve "contact foam breaking" by reducing surface tension, quickly inhibiting bubble generation in high-foam generation links such as coating grinding and dispersion, and ink thinning.
Anti-Filler Interference: The special formula design makes it not easy to be adsorbed and wrapped in a high-filler environment, and can continue to maintain activity in the system, inhibiting the regeneration of foam during storage and construction (such as spraying, troweling), and the foam-inhibiting time is increased by 40% compared with ordinary mineral oil defoamers.

Low Dosage and Optimized DispersionThe conventional dosage is only 0.1%–0.6% of the system mass to achieve the ideal defoaming effect. After addition, no additional high-speed dispersion is required, and it can be uniformly dispersed at a stirring speed of 200–500 rpm, avoiding coating shrinkage defects caused by uneven dispersion. At the same time, it does not affect the system viscosity and leveling property, and is suitable for water-based inks and high-solid coatings sensitive to construction performance.
Full-Scenario Process CompatibilityIt is friendly to roller coating, spraying, curtain coating of water-based coatings, gravure/flexographic printing of inks, and troweling process of adhesives. It will not cause defects such as oil spots and color difference on coatings or printed matter due to defoamer aggregation, and is especially suitable for exterior wall coatings and packaging printing inks with high filler content.

III. Application Fields

Application Scenarios	Specific Role Description
High-Filler Water-Based Coatings	Suitable for exterior wall texture coatings (filler content ≥ 40%), fireproof coatings, anti-corrosion coatings, etc. It solves foam problems during grinding and construction to ensure that the coating film is smooth and has uniform hiding power.
Water-Based Printing Inks	Suitable for gravure water-based inks for packaging printing, paper coating inks, etc. It eliminates foam during ink preparation and printing to ensure clear pattern dots and accurate color reproduction.
Latex Adhesives	Used in latex systems containing fillers such as woodworking glue and packaging glue. It inhibits air bubbles mixed in during stirring, avoids cavities in the bonding layer that lead to reduced strength, and improves bonding reliability.
Other High-Filler Systems	Suitable for water-based putty, mortar coatings, PVC paste resin, etc. It controls foam generated due to filler dispersion during production and improves product appearance and construction performance.

IV. Usage Recommendations

It is recommended to add during the mixing and grinding stage of fillers and base materials, and disperse synchronously with fillers to ensure that the defoamer uniformly wraps the filler surface. If used in the finished system, it can be added slowly in the later stage of paint mixing and stirred at a low speed for 10–15 minutes.
For high-viscosity and high-filler systems (such as high-build coatings), it is recommended to pre-dilute the defoamer with 10% deionized water before adding to enhance the dispersion effect.

High-filler coatings/mortars: 0.3%–0.6% (of the total system mass);
Water-based inks/adhesives: 0.1%–0.3% (of the total system mass);
Before the first use, a small test (such as preparing 100g of filler-containing samples to test the defoaming effect of different dosages) is required to determine the optimal dosage to avoid slight oil floating caused by excessive addition.

Operation PrecautionsAvoid adding at the same time as strongly polar additives (such as amine neutralizers), and it is recommended to interval more than 15 minutes to prevent defoamer demulsification. When used in ink systems, it is necessary to confirm the compatibility of the defoamer with the color paste, and printing adaptability tests can be carried out first.

V. Storage and Safety

Storage Conditions: Store in a cool and dry place at 5–35℃, avoid direct sunlight or freezing. After opening, seal the drum mouth tightly and use it up within 6 months to ensure performance.
Shelf Life: The shelf life is 12 months in the unopened state (subject to the date marked on the package).
Safety Tips: Wear protective gloves and goggles during operation. If it comes into contact with the skin, wash with soapy water. This product is not a dangerous good and should be handled as an ordinary chemical during transportation. For details, refer to the MSDS Safety Data Sheet.
