Frequently Asked Questions
What is the mix ratio for MG Chemicals 832B?
The mix ratio is 2 parts A to 1 part B by volume (2A:1B). This ratio is compatible with most standard two-component dispensing equipment. Accurate metering is critical — incorrect ratios will result in incomplete cure.
Can 832B be used for submersion applications?
Yes — it provides extreme resistance to water and humidity and is suitable for applications requiring submersion protection of electronic assemblies.
What is the service temperature range?
832B performs reliably from -40°C to +140°C (-40°F to +284°F), making it suitable for both cold-environment and elevated-temperature industrial applications.
How does 832B cure?
It can be cured at room temperature or accelerated with elevated heat. Refer to the Technical Data Sheet for specific cure schedules and handling strength timelines.
What sizes does MG Chemicals 832B come in?
832B is available in four sizes: 375 mL (2-bottle kit), 450 mL (dual cartridge), 2.55L (3-can kit), and 60L (3-pail kit). This listing is for the 60L production-scale pail kit. Contact MTE Solutions for other sizes.
