In sealant systems, UltraCarb provides excellent slump resistance and a higher gunning rate than other fillers. This is because the chemically basic nature of the Huntite and Hydromagnesite minerals and their high surface area makes them efficient acid scavengers in pH-sensitive polymer systems.
MicaFort improves adhesion
When you add the Mica to the adhesive, it provides barrier properties and better adhesion to the substrate. You can use both Muscovite Mica and Phlogopite Mica for your adhesives and sealants. We promote both Muscovite and Phlogopite Mica under our MicaFort brand.
Chalk extends TiO2
When Chalk is uncoated, our customers use it as an extender for titanium dioxide. This is especially the case in acrylic sealants where the colour and opacity are maintained. Alternatively, coated Chalk products improve dispersion properties and reduce plasticiser demand in non-water based sealant systems.
ATH for fire retardancy
Many customers use Aluminium Trihydroxide (ATH) within adhesives and sealants to provide fire retardancy and smoke suppression. You can achieve high filler levels with this mineral. On top of that ATH remains stable within the adhesive or sealant at temperatures below 205°C.
Please get more information, your sample or quotation on our natural mineral fillers for adhesives and sealants by contacting your regional sales partner.
Fordacal cost and technical benefits
The marble extenders (Fordacal) offer significant cost benefits and advanced technical solutions. The product works particularly well in conjunction with Titanium Dioxide.
We have a variety of grades which improve:
