(II) Product Introduction

Polyurethane electronic potting glue is a kind of electronic sealing material recently developed by our company. It is used for the sealing of electronic devices such as computer controller, water heater electronic components, sanitary ware and other household appliances and other electrical appliances of automatic washing machines, and it is used for moisture-proof and waterproof. Buffer, shock absorption and other effects.

advantage:

1. Transparent color and good appearance;

2. Short defoaming time (about 3 minutes), complete deaeration, easy operation;

3. Curing faster

4. The relevant performance can be changed to meet the different requirements of different users.

Instructions

1. Weigh AB two components according to A:B=1:1 (weight ratio), mix, and mix well;

2. Place in a vacuum box and pump 2Kpa vacuum for about 3 minutes;

3. After the foam is pumped out, it is poured into the mold containing the circuit board of the electronic product, and cured after more than 2-3 hours to form a preliminary gel, which can be used for the next operation.

Storage and transportation methods and precautions:

1. Non-dangerous goods of this type are stored and transported as general chemicals.

2. Keep in sealed condition. It is forbidden to mix in water and sundries and to prohibit pyrotechnics.
