Please note this silicone is powder filled, the filler is added to allow the silicone to withstand high temperatures for hot materials, therefore adds weight to the silicone, so the weight to volume ratio is considerably different, all our high temperature kits are sold by weight.
Base and catalyst use universal containers for various kit sizes and are supplied by weight, while the supplied containers may not be full, they will contain the correct amount of both base and hardener according to the listing. At point of packaging and dispatch lids may be taped to prevent damage or spillage during transportation.
This silicone is not suitable for food use. It is also not suitable for direct use on skin.
