HM-E-340Product Information

Features：

Transparent.

Room temperature cure or rapid hot cure.

Low shrinkage.

Stable and flexible from-50℃to 250℃.

Typical properties:

Note: The sample was prepared at25℃.

Mixing

The two components should be thoroughly mixed using a weight or volume ratio of 1:1 until the mixture has a uniform color. Vacuum de-air is recommended. A residual pressure of 10-20 mmmercury applied for 5-10 minutes will sufficiently de-air the material.

Pouring the mixture and curing

Pour the mixture onto the original as soon as possible, avoid air entrapment the catalyzed material would cure to a flexible rubber within 24 hour at room temperature and then the mould can be removed. If the work temperature is significantly low, the cure time would be longer. Heat accelerating the cure is possible, but this will produce some apparent shrinkage of the mould due to the difference in volume contraction on cooling between the silicone rubber and original.

Inhibition of cure

All addition-cured silicone elastomers are suspect to cure inhibition when contact with certain materials and chemicals. Inhibition has occurs if the elastomer is only partly cured after 24 hours or has a sticky suface in contact with another material. Amines and sulphur-containing materials are strong inhibitors, as are organotin salts used in condensation cure silicone elastomers. Mixing containers, originals and release agents should be checked for any inhibition effect before use.

Usable life and storage

Base A and curing agent B has a shelf life of 12 months from the date of manufacture.
