Ultra-low hardness two-component curing gel urethane system
PANDEX GC
DIC's uniquely designed ultra-low hardness, highly transparent gel urethane product (two-component curing type consisting of polyisocyanate and polyol components)
Features
-
Ultra-low hardness (Asker C, Asker F range)
-
High transparency
-
Excellent durability
-
High tan δ value over a wide temperature range
Ultra low hardness
Due to the flexibility resulting from the ultra-low hardness, the molded sample stretches well as shown in the top row (the bottom row is the original sample).
High transparency
The "DIC" lettering is clearly visible through the molded sheet in the upper right corner.
Main Application
-
Various buffer materials (for optical applications such as air gaps).
-
Shock absorbing material.
