ThinkBond 8 Premium Electrical Insulator Adhesive for Polymer & Metal Bonding
Product Description
ThinkBond 8 is a specialized insulator adhesive designed for bonding critical electrical components like polymeric insulators. This one-coat, heat-reactive primer creates superior bonds between peroxide-cured elastomers (VMQ, FKM) and substrates like steel, aluminum, galvanized metal, and resin composites during vulcanization. Its defining characteristic is an extremely low electrical conductivity, making it the essential insulator adhesive for applications where preventing current leakage is paramount. ThinkBond® 8 is also a heavy metal-free, environmentally conscious solution.

ThinkBond 8 Insulator Adhesive - Frequently Asked Questions (FAQ)
-
Q: What makes ThinkBond® 8 suitable specifically as an insulator adhesive?
A: Its extremely low electrical conductivity is the critical property, preventing current flow and ensuring the insulator functions correctly.
-
Q: What elastomers can ThinkBond® 8 bond for insulator production?
A: It is primarily formulated for bonding peroxide-cured silicone rubber (VMQ) and fluorocarbon rubber (FKM), the most common elastomers used in polymeric insulators.
-
Q: How is ThinkBond® 8 applied?
A: It can be applied via dipping, brushing, or spraying. Dilution with MEK or MIBK is required: typically 1:1 for dip/brush, 1:2 for spray. Surface preparation (cleaning & sandblasting >15μm Ra) is crucial.
-
Q: How long does ThinkBond® 8 take to dry?
A: Drying at room temperature takes 20-30 minutes. Oven drying below 82°C can accelerate this. Ensure the film is completely dry before vulcanization.
-
Q: Is ThinkBond® 8 safe to use?
A: While heavy-metal-free, it contains volatile solvents (MEK/MIBK). Use with adequate ventilation, wear protective gloves and a mask. Avoid skin contact and ingestion (fatal if swallowed). Always consult the MSDS before use.
-
Q: How should ThinkBond® 8 be stored?
A: Store sealed in a cool, dry, well-ventilated place away from heat, sunlight, and open flame. Shelf life is 6 months at 21-27°C.
