Two-Part Silicone Mold Putty For Dental Impression
Introduction
Silicone Impression Putty is a hydrophilic addition silicone rubber impression material, Silicone Impression Putty contains two components, Part A is platinum catalyst, and Part B is
hydrogen containing polysiloxane. Silicone Impression Putty comprises liquid material and powder material. The main raw
material is a silicone oil, silicone resin, alumina, quartz powder
and etc.
Main Features
1. Good plasticity, small volume incorporation rate, it needs only
3-5min to vulcanize into elastomer at oral temperature, very easy
to remove from the mouth after the stamp, and has good chemical
stability.
2. High accuracy of mold impression, capability of reproducing the
fine structure of the mouth, with good elastic recovery, and good
tear strength and dimensional stability, it can provide accurate
and reliable morphological basis for clinical dentistry.
3. Silicone Impression Putty has compatibility with almost all
model materials, reusable for a period of time and can be
sterilized.

Usage Instruction
1. Under the room temperature, take the same amount of base
component (blue) and catalyst component (white).
2. Mix the two components together. It is recommended to use the
blue spoon to take the base component and white spoon to take
catalyst component.
3. Use your fingertips to mix the two components together and knead
for at least 30 seconds until they are mixed completely.
4. Close the lid immediately after usage, the cover can not be
interchanged.
Package
350g,500g, 1kg, 5kg, 10kg, 20kg,25kg
Storage : it has a shelf life of 12 month in original package at a
cool dry place.
Precautions
1. Do not use natural rubber gloves. It is recommended to use
disposable polyethylene plastic gloves.
2. The product contains platinum catalyst, sulfur, phosphorus,
amine, etc. will slow down or even stop the curing reaction, and
thus it must avoid sulfur, phosphorus, amine, acrylic and meth
acrylic acid esters and other chemical products in use.
3. Close the lid tightly and immediately after use, keep it in cool
place, and be refrigerated in summer.
4. The temperature has a significant impact on the curing time; the
curing reaction will slow down at low temperature, and speed up at
high temperature curing speed. It should adjust operation rhythm
according to the environment and the finger temperature.
5. It is strictly recommended to use the same amount of base and
catalyst. Unequal amount will lead to delayed or accelerated cure.
