Rtv Two Component Low Viscosity Compound Resin Sp2204 - China

price: contact company for price

SP2204 is two component no solvent RTV/ Heating curing resin

elastomer compound


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


It' s specifically formulated for automotive sensors,

switches, and other electrical devises requiring

environments protection.


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.

Manual process

Temperature: Before using, keep the material under 25 ± 2ºC

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 ºC 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.
