Product Description
LINQBOND PM-PU211 is a two-component flame retardant polyurethane material engineered for wide applications such as bonding of pre-treated materials, potting, and encapsulation. PM-PU211 system is composed of naturally occurring hydroxyl resin and isocyanate-based hardener, exhibiting rigid elastomer properties upon curing.
LINQBOND PM-PU211 passed HWI, HAI and CTI tests with PLC 0 rating and relative thermal index (RTI) value of >105°C. Additionally, with a UL 94 V-0 flammability rating and Class B insulation, PM-PU211 guarantees strong performance and outstanding reliability. This product is deliberately formulated without the inclusion of substances prohibited by the European Union RoHS and REACH. LINQBONDTM PM-PU211 seamlessly integrates into your projects, ensuring a smooth and reliable package. Viscosity and pot life of PM-PU211 can be adjusted to match the customer requirements.

Additional Information
Processing Instructions
Before mixing, stir both Part A and Part B to homogenize.
Mix components A and B according to the specified weight ratio. Stir thoroughly to ensure uniformity while preventing air from introduced into the mixture. Ensure contamination is avoided.
To ensure complete mixing of both parts, machine mixing and dispensing are recommended. Static and dynamic mixer can also be used for mixing.
Degas the mixture to remove the bubbles for about 10 minutes. Do not fill the container more than half full to prevent overflowing during degassing.
Gradually pour the mixed compound into the device being potted.
Allow the potted workpiece cure at 25°C until the surface is dry. Full curing typically occurs within 24 hours. The curing process is influenced by temperature variations; generally, higher temperatures result in faster curing, while lower temperatures lead to slower curing.
Precautions
Use the mixture promptly after combining components A and B to prevent a significant increase in viscosity.
If the components have been stored for an extended period and exhibit precipitation or stratification, they should be thoroughly mixed before use.
Packaging
Part A is available in 30 kg open top plastic bucket. Part B is available in 250 kg metal barrels or 40 and 24 kg plastic cans.
Storage and Handling
Store in a ventilated, dry, and clean environment at 25°C–40°C Keep away from fire and heat sources. It is strictly forbidden to store in outdoor environments. At proper storage conditions, Part A has a shelf life of 6 months and Part B has a shelf life of 12 months.
