Why does the mold appear oily?

The mold itself does not emit oil; the 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 polished or if the release agent is not applied evenly on the mold surface.

What are the wonderful usages of mold silicone?

It is used in toy, gift, furniture, character reproduction, building decoration, resin handicraft, candle craft, and sculpture industries for product replication.

Product Q&A

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

This may happen due to adding too much silicone oil which destroys molecular weight, adding too much catalyst (over 2% for tin catalyst) which reduces tension, or using wrong hardness for the design size.

Q:Why does the silicone mold get burnt out?

Burnt out molds occur when using unsaturated resin without demoulding within 3 minutes, as the resin generates great heat when the curing agent is added.

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

This is due to condensation silicone rubber absorbing moisture from the air. Solution: 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 excessive catalyst (over 5%), or using the mold prematurely before 24 hours of curing.

Q:Why does the mold silicone have poor tension?

Poor tension results from adding large amounts of silicone oil to reduce viscosity, making the rubber too soft and reducing its durability and service life.
