Description of RTV Silicone for Mold Making:

RTV Silicone for Mold Making is generally named two-components silicone rubber, Part A and part B. It features an exceptional fluidity and good operability. The mixing ratio is 100:3, mainly be suitable for making molds application.

Typical applications of RTV Silicone for Mold Making:

RTV Silicone for Mold Making  could be mainly used for making concrete stones, wax molds, PU molds, resin molds, gypsum casting, candle molding and chocolate , candy and any other FDA food product mold making,prototyping etc.

Features of RTV Silicone for  Mold Making:

Outstanding release properties

High flow-ability and long working time

Medium Hardness

High tear resistance

High elasticity for easy removal of complex replica parts

Can be made thixotropic (non flow-able) for vertical surface replication.

 How to calculate that how many silicone you probably need to make one mold?

1) measure the size, the length, the width and the height of the  mold

2) Computational formula: [{length+3}*{height+3}-length*width*height]* density  of the   silicone rubber

NOTE: usually, the density of our OTT Silicone Rubber would be about 1.08~1.10 according to the different models.
