PU200W 电子传感器灌封胶

PU200 has been developed as a cold pour system to encapsulate piezo sensors and to stick surface mounted sensors.
The material is available in 4kg kits

METHOD OF USE
The resin is a filled system and therefore some degree of sedimentation may occur, particularly if the resin has been left standing over long periods of time or stored at elevated temperatures (in excess of
25oC).  This can be readily dispersed by mixing with an electric drill and suitable attachment or a broad
bladed spatula.

The resin and hardener are mixed in the ratio:
7.22 : 1   By weight
7.53 : 1  By volume

Colour of mixed system

Black

Density of resin

1.86

Density of hardener

1.23

Density of mixed system

1.74

Viscosity of resin

15,000 cp at below 15oC

Viscosity of hardener

4 Poise at below 15oC

Viscosity of mixed system

13,000 cp at below 15oC

Pot life

5 - 10 minutes at below 15oC (150g mass)

Set time

10 - 15 minutes at below 15oC (150g mass)

Full Cure time

2 days

Peak Exotherm

60oC (150g mass)

Shore D Hardness after 24hrs at room temp.

A: 75        B: 70 after 5 seconds



Gel time is very much dependent upon ambient temperature, mixing time and road temperature
It should be noted that road slots are natural heat sinks and cure times may be extended by the prevention of exothermic heat developing.

Cleaning Equipment
All equipment should be cleaned before the compound has hardened.

Storage
The resin and hardener should be stored separately in tightly sealed containers until required for use. The shelf life on this material is 12 months unless otherwise stated on the label.
Preferred storage temperature is around 20oC but must not be allowed to reach freezing or exceed
temperatures of 30oC.

CAUTION
Polyurethane systems are generally quite harmless to handle, provided that certain precautions normally taken when handling chemicals are observed. The uncured materials must not, for instance, be allowed to come into contact with foodstuffs or food utensils, and measures should be taken to prevent the uncured materials from coming into contact with the skin. The use of barrier creams or impervious gloves is advised.  The skin should be thoroughly cleansed at the end of each working period, either by washing with soap and warm water or by using a resin removing cream - use of solvents is to be avoided. Disposable paper towels - not cloth towels should be used to dry the skin. Adequate ventilation of the working area is recommended.

Polyurethane hardeners are moisture sensitive. Containers of both resin and hardener should be kept tightly closed when not in use to prevent ingress of atmospheric moisture.
