Operation instructions

1. Mix part A and pars B evenly with 1:1 mixing ratio.

Notes: 1) Weigh the two parts exactly by electronic weight. For example, the operation time will be shorten after adding too much catalyst.

1. Mix part A and part B evenly. Otherwise the silicon rubber will be partly solidified which will make the finished molds meet a short life and waste silicon rubber.

 

    2. Vacuum pumping

Notes: 1) This step is not have to have, but it is best if there is one. It will discharge all air in the mixture successfully, so as to ensure that there
will be no bubbles in the finished mold.

2) This step is less than 10 minutes. Otherwise, it
Will cause cross-linking reaction, and no more
further steps will be available. 
 

1. Pouring casting

Notes: We suggest to set the mold for another 12 hours after demould before put it into large production.




Handing and Storage

1. Precautions for safe handling:

Protective measures: Training should be provided to anyone working with or near this material. Training should cover potential health effects and proper handling techniques. Avoid contact with eyes, skin and clothing. Avoid ingestion and inhalation.

Measures to prevent fire: Ensure good local exhaust ventilation. Keep container away from any sources of ignition or heat (e.g. open flames, hot surfaces). The work area should be equipped with the corresponding species and quantity of emergency equipment, spills emergency treatment equipment and appropriate storage material.

Measures to prevent aerosol and dust generation: Ensure good local exhaust ventilation.

Measure to protect the environment: Do not allow this products to be released to the environment without proper treatment.

Advice on general occupational hygiene: Eating, drinking and smoking should be prohibited in areas where this material is handled, stored and processed.

 

1. Conditions for safe storage, including any incompatibilities:

Technical measures and storage conditions: Store in a cool, dry, well-ventilated area away from 
incompatible substances, feedstuffs, beverages and foods. Keep away from heat, sparks and flame. Treat carefully, avoid physical damage to containers. The storage area should be equipped with the corresponding species and quantity of emergency equipment, spills emergency treatment equipment and appropriate storage material.

Requirements for storage rooms and vessels: Keep container tightly sealed.

Package
5KG, 20KG, 25KG and 200KG per drum.
(There are metal drum and plastic drum for your choice for 5KG and 20KG)



Shelf life
Twelve(12) months when stored under dry and cool place by original package under 25ºC.
 

Features:

1.Almost no shrinkage

2.Good fluidity, operability and excellent operation

3.Good resistance to weather, temperature, aging, acid

4.Excellent tear strenght, comfortable duplcation times

5.High chemical resistance to aggressive components of some types of resins

6.Food grade silicone(environmental, odorless and nontoxic

7.High resistance to high temperature and aging(resist -60 to 250ºC)

Operate Process:

1. The surface of the original is clean and free. 

2. Weight 100 Part A base and 100 part B in a clean container.

3. Stirring Part A base silicone before using thoroughly , as filler separation may occur upon prolonged storage.

4. Mixing Part A and Part B evenly until completely dispersed in the base. 

5. Pouring the mixed base silicone and platinum curing agent as soon as possible onto the original

6. De-mold after 24 hours ,it is will improve the replicate times of silicone mold.

Note:It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mix to completely expand and then collapse. After a further 1-2 min under vacuum, the mix should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture. So a suitably large container should be chosen.
