Product Description
Kootai 9210T Thermal Adhesive is a neutral-cure, RTV silicone-based compound specially designed for thermal management in electronics. Its high viscosity and single-component format make it easy to apply without additional mixing. Once cured, it forms a resilient, flame-retardant elastomer with strong adhesion to metals, glass, plastics, and PCBs. It combines excellent dielectric strength (25 kV/mm), volume resistivity (1.210 cm), and weather resistance, making it ideal for bonding components exposed to heat cycles and demanding environments. It shows no copper corrosion, is safe for electronics, and meets industrial insulation and flame-retardance standards.

FAQ
Q1: What is the curing behavior of 9210T?
A: Curing progresses with humidity at ambient temperature. Tack-free time is approx. 1015 minutes at 25C/50% RH. Full cure depends on thickness and conditions but typically completes within 57 days.
Q2: Can it withstand thermal cycling?
A: Yes, it operates reliably between -50C and +200C without cracking or loss of adhesion.
Q3: Which substrates does it bond well with?
A: Excellent on copper, aluminum, stainless steel, brass, glass, ABS, PET, and PCB. Moderate adhesion on PC; poor on PP/PE unless pretreated.
Q4: Is it electrically insulating?
A: Yes, with dielectric strength 25 kV/mm and low dielectric loss (0.015 at 50Hz).
Q5: How should it be stored?
A: Store sealed in a cool, dry place under 25C. Shelf life is 6 months.
