Why does the mold appear oily?

The mold itself does not emit oil. Oil is caused by adding composite silicone oil (containing white mineral oil) during operation.

Why does the silicone mold have traces, streaks, and unevenness on the surface?

This occurs if the original model is not smooth or polished, or if the release agent was not applied evenly.

What are the wonderful usages of mold silicone?

It is used in toy, gift, furniture, character reproduction, building decoration, resin crafts, candles, plastic toys, gypsum crafts, glass products, and sculpture industries.

Product Q&A

Q:Why could the silicone mold be reused only for a few times?

Reasons include adding too much silicone oil which destroys molecular weight, adding too much catalyst (more than 2% for tin cure) which reduces tension, or using wrong hardness for the design type.

Q:Why does the silicone mold get burnt out?

This happens when using unsaturated resin without demolding within 3 minutes, as the resin produces great heat. Our rubber includes special materials to resist high temperatures.

Q:Why does the silicone mould appear to be dry outside but wet inside?

Condensation silicone rubber solidifies by absorbing moisture. To fix this, add 0.05% water and stir briefly at low speed before use.

Q:Why is the tear strength of silicone molds weak?

Weak tear strength is caused by adding too much silicone oil, adding too much catalyst (recommend max 5%, ideally 2%), or using the mold prematurely before 24 hours.

Q:Why does the mold silicone have poor tension?

Adding large amounts of silicone oil to reduce viscosity makes the rubber too soft, resulting in poor tensile strength and short service life.
