Chemical compatibility tests were conducted to decide suitable materials which do not react to each other.
What causes yellowish?
Compatibility Test1 One of three items could affect yellowish:
Oxime silicone, Water, Flaxseed oil. Oxime silicone sealant
was used for attaching the wood cover.
When Silicone and Flaxseed oil meet aerogel respectively,
contact surface of Aerogel becomes white gradually .
Aerogel becomes white also when it absorbs physical shock.
It was interesting that water doesn’t affect Aerogel at all, while the sticky substance
of Aerogel surrounding is easily wiped out or melted with water flow.
Since none of components changes the color of Aerogel from the test1, the combination of each two components to Aerogel were newly set up.
Obviously, the combination of Oxime silicone and flaxseed oil affect yellowing. After 2 months, it becomes brown.
