U4720 + D72 two-component resin, polymerization at ambient temperature

Application:
Half hard system is used for electronic flooding.
- transformers,
- PCB,
- Electronic components flooding.

Description:
It is excellent resin with very good physical and electrical preferences. It is self - extinguished, and its compatible with insulation system class B.

Storage conditions:
We recommend:
- Storage away from light source, heat or cold, in the closed original container.
- PRODUCT HIGHLY SENSITIVE FOR HUMIDITY,
- storage time: 6 months in temperature
  10°C - 25°C.
For hardener: 12 months in temperature 5°C - 30°C,
- usage:open in ambient temperature

Hygiene and protection:
- Resin components don't corrode.
- it is prohibited to touch with skin, or inhale
- it is recommended to use gloves, glasses and mask.

Packing:
- in containers 1, 5 i 20 kg and barrels 220 kg,
- part B is delivered in corresponding proportion to part A.
