Two-Part Silicone Mold Putty For Dental Impression
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.

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.
