Polyurethane resins - impregnation methods

Description:
Different physical, chemicals, electrical preferences make polyurethane resins excellent material in electronic industry

Preferences:
Polyurethane resins has following preferences:
- exothermic constant. ,
- weak shrinkage,
- penetration,
- adherence properties.
- self-extinguishing,
- thermal conduction.

Resin preparation:
They are delivered as two components, which react to the ambient temperature. They can be mixed manually or automatically.
- Preliminary resin heat up to 40C Caution. This can shorten resin lifetime.
- Add hardener in proportions shown on the table, then mix.

Resin usage:
Dependent on resin type and application it is recommended to:
- Preliminary heat up parts (60°C max)
- Pour out resin in the room temperature and the atmosphere pressure.
- in some special cases it is possible to pour resin in vacuum.

Polymerisation:
- it is recommended in ambient temperature (23°C),
- it is possible to speed up polymerisation by putting parts in max temperature 60C,
- later hardening in some cases allow to give resin better thermal and mechanical preferences.

Safety measures:
Because of hardener chemical properties it is not recommended to leave it on air for to much time.

Storage conditions:
3-6 months depending on the product, in original, closed container. Far away from sun or other heat source.

Packing:
In containers: 1, 5 and 30 kg or in barrels 200 kg

Protection and hygiene.
They are not much toxic. Skin contact not recommended.
