This is a  500 gr Silicon Rubber bicomponent that vulcanizes by rapid-hardening polyaddition reaction. It is suitable for quickly making small molds, as fossil mono-valva. It has a very low ammount of liquid silicon so it is suitable for high quality cast with low wet look. The result is a vulcanized of medium hardness and low elasticity. It can also be used to draw anatomical casts directly on the skin, since the product is non-toxic and antiallergic: the certificate of suitability issued by an authorized laboratory is available. In any case avoid contact with the eyes: in the event of contact, wash with plenty of water and consult a doctor if necessary.
