CAS No.14228-73-0
1,4-cyclohexanedimethanoldiglycidylether
Shofree CDMDG
CDMDG has an alicyclic structure, it has excellent properties such as hydrophobicity, low water absorption, and low dielectric property.
In addition, it has
low molecular weight and liquid at room temperature, so it has good affinity with various epoxies.
Merit
Low water absorbency, Low dielectric, Liquid in r.t.
Total Cl
＜50ppm
