Product Description
Two Component Polyurethane Compound for Metals and Plastics Adhesion (SP2204)
SP2204 is two component no solvent RTV/Heating curing resin elastomer compound
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.

Founded in DEC. 2003, SEPUNA has been engaged in researching, manufacturing and marketing automobile sealant and adhesive for 9 years.
Since the foundation, SEPUNA Chemical has been focusing on adhesive's researching and application. Then in 2005, We acquired PUNADE technology which is from Switzerland.
Within 9 years, SEPUNA mainly develops Silicone, Polyurethane and Epoxy resin adhesives. And in the future, we will enlarge our line to Unsaturated, Natural and Acrylic Resin adhesive.
After 9 years' improvement, by the keep researching and innovation, SEPUNA is already a mature adhesive supplier with the core competitiveness.
