Because heavy calcium carbonate products have the advantages of narrow particle size distribution, large specific surface area, low oil absorption and low water absorption, they are used in many industries and are also recognized by users. The following small series introduces the application of heavy calcium carbonate in adhesives and sealants.

1. Heavy calcium carbonate has become the main raw material for reactive adhesives, hot melt adhesives, neoprene adhesives, water-based adhesives and sealants. Under the premise of drastically reducing costs, the bonding performance has been comprehensively improved;

Second, wood sticky agent special heavy calcium carbonate application surface is wider, such as PVC plastisol can improve its rheological properties, in silicone structural sealant can play a role in enhancing and reducing costs, applied in hot melt adhesive It can play an incremental reinforcement and heat resistance;

Third, heavy calcium carbonate can play the role of thickening and thickening in water-based adhesives. Application in adhesives and sealants can significantly reduce costs and improve bonding performance.

The above three points are the introduction of the application of heavy calcium carbonate in adhesives and sealants. Of course, it is not only for this purpose. The above content is for your reference. It is generally better to understand its use. Go to choose and use.
