Moisture Absorption

Water absorption impacts both the electrical properties and processability of dielectrics. Extended bake-out cycles are needed to remove water from materials with high (> 1%) moisture content or else blistering and delamination occur. CYCLOTENE* Advanced Electronics Resin products are known for their extremely low water absorption. No bake-out is required during processing
