FAQs


If your question is not listed here, please get in touch.

Where are the product number, batch number and manufacture date marked on the cartridge?

They are inkjet printed around the nozzle end of the cartridge

I’m half way through moulding my sculpture and I’ve run out of rubber, can I add more to it later? How long can I leave it before adding more?

As long as the surface of the cured rubber is kept dust and grease free, more rubber of the same type can be poured on top and will bond with the surface. There will be no detectable join. (unless a different coloured catalyst is used, of course) If the above is strictly adhered to then there are no time constraints.

How can I make the silicone cure more quickly?

1 parts condensation cure: - by increasing the humidity 2 parts: Silcosets - increase the amount of catalyst to a Maximum of 1% - Apply heat, again not more than 40C 900 Series - Use Cat Red 5 – see technical data sheet for more information Addition Cure 2 part – Increase temperature of curing oven – see individual data sheets. It should be noted however, that the slower the curing of silicone rubber, the better the quality and durability. You will note that any testing undertaken is done after 7 days, when the rubber has fully cured and all volatile products have evolved at which point the rubber has reached its optimum properties.

How can I repair my torn mould?

by using a 1 part RTV - ensuring the edges of the tear are clean and grease free - apply as per the Technical Data Sheet

How many cartridges will I need to complete the job?
