Aglime Adhesives & Sealants Increasing Performance - Reducing Costs

There are many examples of essential manufacturing and infrastructure purposes that utilise high-performance and general-purpose sealants based on a variety of polymers. These include the construction of housing, offices and factories, the manufacture of automobiles (such as cars, buses, truck and planes), and the building of major roads and airports. Furthermore, there are a huge range of products that depend on adhesives as part of their manufacture. Many of these sealants and adhesives could be improved simply with the addition of ground calcium carbonate (GCC). This would be a cost-effective way of increasing the performance of an array of products, including adhesives and automotive and construction sealants. GCCs add to the whiteness and opacity of a sealant or adhesive, as well as decreasing costs and increasing the concentration of solids.

  • Automotive Sealants
  • Construction Sealants
  • Adhesives

Most sealants and many adhesives include a ground calcium carbonate in the formulation as a filler to reduce costs and increase the solids level. GCCs also contribute to opacity and whiteness.


Ground calcium carbonate (GCC) minimises expenses by substituting with polymers and other more costly raw ingredients in a product, and increasing performance by virtue of its features (such as rheological control, opacity, brightness, resistance to weather, resistance to cracking and its ability to absorb sound).


Ground calcium carbonate – or GCC – is a handy ingredient to have, particularly for automotive sealants. GCCs are utilised to reduce the costs of producing sealants by acting as a filler, and they add a slight thixotropic viscosity. Finer GCC grades result in higher viscosity, and lower grades produce higher loadings and are the most cost effective.

.What is an Adhesive? What is a Sealant? How Do They Differ?

Adhesives and sealants are different products, although you may see them grouped together as though they performed the same function.


Adhesives are products that bind two surfaces together through bondage. Adhesives usually are applied as a thin layer between two such surfaces. Two factors are important in order for a substance to act as an adhesive. The first is that the product must bond with the surfaces to which it is applied, and the second is that the adhesive must have enough strength internally so as to not separate when the two surfaces are pulled apart.


A sealant is designed purely to fill in a space – a joint, gap or cavity that occurs between two surfaces.

A sealant is not designed to stick two surfaces together, rather to form a protective layer against solids (dust or dirt), liquids (such as water on a tile in a bathroom) or gas (for example wind finding its way through a window frame).

Although a sealant must stick to the surface that it is applied to, its main function is to fill the gaps, not stick. Examples of sealants are putties, caulks, mastics, and high-performance sealants.
