Features
1. Low viscosity, easily process
2. Excellent performance on low-temperature and aging
3. Excellent and stably electrical dielectric
4. Very low Water absorption
5. Good adhere to most metals and plastics

Usage
It's specifically formulated for automotive sensors, switches, and other electrical devises requiring environments protection.


Preparations
Material preparation: Stirring in the original drum, then pouring into dispenser.
To avoid bubbles inside of finished products, both tank should be usually kept 40 to 60 minutes under the vacuum pressure 0-2mmHg.
Max tolerance: Mixing proportion of deviation may affect mechanical properties, tolerance should be less than 1%.
Other: Through the production, should always maintain the tank airtight. The compressed gas should be dry if need, otherwise part B will become sticky, and influence the mechanical properties.
Suggestion of molding condition
Machine low pressure Pouring machine
Mould temperature 50-60 o C
Material temperature Part A 25-30 o C
Part B 25-30 o C
Demoulding time 10~60min

Manual process
Temperature: Before using, keep the material under 25 ± 2o C to ensure its reactivity and viscosity.
Mixing: Weigh the material at a ratio according to the above.
Preparation: Dry all containers and mould in 70-80 o C oven for 1-2 hours to remove moisture.
Process: Put A and B into a container. Mixing 1-2 minutes. Degassing under 0.1 Mp negative pressure to avoid the bubble. Then potting smoothly. Should avoid the excessive speed to involving into air bubbles.
Cleaning: Cleaning the containers by organic solvents, such as acetone and chloroform, etc.
