UltraCarb modifies sealants
The industry uses the mineral combination of Hydromagnesite and Huntite (HMH) as a rheological modifier in polysulphide sealants. Furthermore, it is an alternative to precipitated calcium carbonate.
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.
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. High filler levels can be achieved with this mineral and on top of that ATH remains stable within the adhesive or sealant at temperatures below 205°C.

Flowdol and Fordacal cost and technical benefits
The milled dolomite (Flowdol) and marble extenders (Fordacal) offer significant cost benefits and advanced technical solutions. These two products work particularly well in conjunction with Titanium Dioxide.
We have a variety of grades which improve:
