What is GLUDITEC SS2210?
GLUDITEC SS2210 is a two-part, addition-cure (platinum-catalyzed) potting silicone rubber made by GLUDITEC (Glue & Dispensing Technology) for protecting electronic and electrical assemblies. It mixes at a simple 1:1 ratio, cures with no shrinkage and no exotherm, and works from -50°C to +200°C.
After cure it forms a grey, flexible rubber (Shore A 55) with a dielectric strength of 15 kV/mm, volume resistivity of at least 1.0×1014 Ω·cm, thermal conductivity of 0.7 W/m·K and a UL94 V-0 flammability rating. It seals components against water and moisture without inducing mechanical stress on delicate circuitry – a key requirement for PCB, power module and connector potting.
In Vietnam, GLUDITEC SS2210 is supplied by PROSTECH, with technical support for material selection, dispensing equipment and on-site trials. Pack size: 40 kg set (Part A 20 kg + Part B 20 kg).
Key Benefits of SS2210
-
Stress-free encapsulation: addition cure gives no shrinkage and no exotherm, so solder joints and sensitive components are not stressed during cure.
-
Wide service temperature: -50°C to +200°C for parts exposed to thermal cycling, engine-bay heat or cold environments.
-
Strong electrical insulation: dielectric strength 15 kV/mm, volume resistivity ≥1.0×1014 Ω·cm and dielectric constant ≤4.0 (60 Hz) for high-voltage protection.
-
Flame retardant: UL94 V-0 compliant.
-
Heat dissipation: thermal conductivity 0.7 ± 0.05 W/m·K helps move heat away from power components.
-
Waterproof and non-corrosive: protects assemblies from water and moisture without attacking metals or components.
-
Easy 1:1 processing: mixed viscosity 1,500–1,900 cps flows around components; operation time 30–60 minutes; suitable for manual mixing or meter-mix dispensing.
-
Flexible cure schedule: 6–8 hours at room temperature, or 60 min at 60°C, 30 min at 80°C, 20 min at 120°C for faster production.
Applications and Industries
SS2210 is used by electronics and electrical manufacturers who need waterproof, high-voltage protection with low stress on components:
- Electronics manufacturing: potting of printed circuit boards, control modules, sensors and connectors
- Power electronics: power modules, power supplies, drivers and inverters that need insulation and heat dissipation
- Automotive electrics: encapsulation of automotive electric parts exposed to vibration, moisture and heat
- Electrical products: encapsulation of all kinds of electric products that need waterproofing and high-voltage resistance

Frequently Asked Questions about GLUDITEC SS2210
Q: What is GLUDITEC SS2210 used for?
A: SS2210 is a two-part addition-cure potting silicone for protecting electronic components, PCBs, power modules, connectors, automotive electric parts and other electrical products against water, moisture and high voltage.
Q: What is the maximum operating temperature of SS2210?
A: SS2210 has a service temperature range of -50°C to +200°C.
Q: Does SS2210 shrink or generate heat during cure?
A: No. As an addition-cure (platinum) silicone, SS2210 shows no shrinkage and no exotherm during cure, so it encapsulates sensitive components without inducing mechanical stress.
Q: What is the mix ratio and working time of SS2210?
A: Part A and Part B are mixed 1:1 by weight; the weighing error between parts should be less than 3%. Mixed viscosity is 1,500–1,900 cps and operation time is 30–60 minutes. Viscosity roughly doubles within 40 to 60 minutes at room temperature.
Q: How long does SS2210 take to cure?
A: It cures fully in 6–8 hours at room temperature. For faster production it can be heat cured: 60 minutes at 60°C, 30 minutes at 80°C, or 20 minutes at 120°C.
Q: Is SS2210 flame retardant and electrically insulating?
A: Yes. SS2210 is UL94 V-0 compliant, with a dielectric strength of 15 kV/mm, volume resistivity of at least 1.0×10^14 Ω·cm and a dielectric constant of 4.0 or less at 60 Hz.
Q: What can inhibit the cure of SS2210?
A: Like other addition-cure silicones, SS2210 can be inhibited by organotin and other metal-organic compounds, sulphur and polysulfide materials, amines and other ammoniac compounds, phosphorus compounds, organic acids and some flux residues. Keep parts clean and dry, and run a small trial on your actual parts before production. PROSTECH can support this trial.
Q: What is the difference between SS2210 and GLT 285W2?
A: SS2210 is a 1:1 addition-cure silicone with no shrinkage or exotherm, UL94 V-0 and a heat-cure option, suited to stress-sensitive and high-voltage electronics. GLT 285W2 is a 10:1 two-part silicone for deep potting over 2 cm that also bonds to metals and plastics such as aluminum and PC.
Q: Where can I buy GLUDITEC SS2210 in Vietnam?
A: PROSTECH supplies GLUDITEC SS2210 in Vietnam in a 40 kg set (Part A 20 kg + Part B 20 kg). Use the Request Quote or Request Sample button on this page, or contact PROSTECH for the TDS, SDS and technical support.
