Product Features

• Enhance Rheological Properties: In solvent - free and solvent systems, when used together with hydrophilic fumed silica and bentonite, it can significantly enhance the thixotropy and anti - sagging properties of the system. Through the synergistic effect with these materials, a stable three - dimensional network structure is constructed, effectively preventing the settlement of fillers in the system and ensuring the uniform stability of the system.
• Wide System Applicability: It has good compatibility with various resin systems such as epoxy resin system, polyurethane system, and acrylate system. Whether in the production of coatings, adhesives or composite materials, it can well play its role in rheological modification.
• Good Storage Stability: It can effectively prevent the system from delamination, precipitation and other phenomena during storage, and maintain the uniformity of the system and the stability of use performance.

Application Fields

• Coating Industry: In solvent - based coatings and solvent - free coatings, when used in combination with hydrophilic fumed silica and bentonite, it can improve the anti - sagging property of coatings, prevent pigment settlement, ensure that the coatings have good leveling property and uniformity during construction, and thus improve the coating quality. It is widely used in fields such as automotive coatings and industrial anti - corrosion coatings.
• Adhesive Industry: It is used in epoxy resin adhesives, polyurethane adhesives, etc., to enhance the thixotropy of adhesives, make them not easy to flow during smearing, facilitate construction operations, and ensure the stable performance of adhesives during storage.
• Composite Material Industry: When producing unsaturated polyester resin - based composite materials and epoxy resin - based composite materials, adding BYK - R607 can improve the dispersion stability of fillers in the system and improve the processing performance and mechanical properties of composite materials.

Recommended Dosage

Based on the total formula, the dosage of BYK - R607 is usually between 0.5 - 3%. However, the actual optimal dosage will be affected by various factors such as the type of resin in the system, the content and type of fillers, and the type of solvent. It is recommended to determine the most suitable addition amount through a series of experiments.

Addition Method

• It is generally recommended to add BYK - R607 to the resin or solvent system before adding fillers such as hydrophilic fumed silica or bentonite to the system, mix them thoroughly and evenly, and then add the fillers to achieve the best synergistic effect.
• It can also be added in the later stage of the production process, but it is necessary to ensure sufficient stirring and dispersion to ensure that the additive is evenly distributed in the system and plays its role in rheological modification.

Storage and Safety

• Storage Conditions: It should be sealed and stored in a cool, dry and well - ventilated warehouse, avoiding direct sunlight and high - temperature environments. The product may delaminate during storage. It can be used normally after being fully stirred before use.
• Shelf Life: Under the condition of meeting the storage conditions, the shelf life of the sealed packaged product is usually 24 months.
• Safety Precautions: Since this product has a low flash point and is a flammable liquid, it should be kept away from fire sources and heat sources during storage and use, and relevant safety regulations for flammable liquids should be strictly observed. Operators should wear appropriate protective equipment such as gloves and goggles when using it to avoid direct contact between skin and eyes.
