Activator S500 / FC500

Print this page Save this page as a PDF Product enquiry

Activators S500 and FC500 are finely micronised hydrating powders that are blended with moisture scavenger additives.

Their unique ability to absorb water from any given film will immediately assist the paint film in forming, and allowing correct cure in adverse weather conditions.  It will prevent the neccessity for all the water to evaporate from the paint system due to the Activator using up water when hydrating commences.

Warning:

Due to the alkalinity of Activators they must only be used in paints, cements and epoxy systems that Special Finishes Ltd recommend.

Uses - Aquepoxy:

We recommend the use of Activators in Aquepoxy, especially when temperatures are around 12°C or lower.

If they are not used in Aquepoxy at these low temperatures, after 2 hours pot life cure of the epoxy will take place, but will entrap water in the film and prevent adequate crosslinking of the epoxy.

Mixing Instructions - Aquepoxy:

First mix required quantity of Aquepoxy A & B that can be used within 20 minutes.  Then to 50% of the mixed Aquepoxy add Activator to form a very thick paste ensuring vigorous stirring using a drill or high speed stick.  Then blend with the remaining Aquepoxy for paint consistency.  Apply immediately. Quantities of Activator from 5% to 25% can be used.  Approximately 200 grams up to 1 kg of Activator per 4 litres Aquepoxy.  Only add sufficient Activator to give a reasonable rolling or brushing viscosity.

If difficulty is found in obtaining a smooth, lump free consistency, or problems with rolling, then we recommend pre-mixing Activator to a thick smooth lump free paste with water, then immediately add to pre-mixed A & B Aquepoxy.  Then use as required.

Uses - Cement Compounds:

Activators S500 and FC500 can also be used to speed up cure in Shieldpatch/Strongwall/Scribe and all cement high build powdered compounds.

Quantities generally from 1% to 10% have proven very beneficial in adverse weather conditions, especially in temperatures below 10°C

Mixing dry is recommended with Strongwall or any cement compound, then mix with the required water quantity.

Activator can be used with some types of Special Finishes Ltd paints and textures, but due to high alkalinity approval from Special Finishes Ltd must be obtained before uses.

Pot Life S500 - 60 minutes approximately

Pot Life FC500 - 30 minutes approximately
