Product description

MDSI 7320 is hygroscopic curing of neutral dealcoholized silicone, adding special thermal conductive materials made of thermal silica gel, after curing to form a flexible rubber body, fully in line with the EU ROHS directive requirements. The release of alcohols during the curing process is non-corrosive to polycarbonate (PC), copper and other materials, and has good bonding and sealing performance for most materials, protecting electronic products in a stable state under harsh conditions.

How to use

Operation process

Clean the surface: the surface of the sticky or coated material is cleaned, and the rust, dust and oil are removed with cleaning agent.
Sizing: Cut the nozzle to the required size and load it into the glue gun. Squeeze the glue solution onto the cleaned surface for an even distribution. When bonding, the adhesive surface can be closed and fixed.
Curing: curing process is a curing process from the surface to the inside, within 24 hours (room temperature and 55% relative humidity) glue will cure 2 ~ 4mm depth, if the glue position is deep, especially not easy to access to the air, the full curing time will be extended, if the temperature is low, curing time will also be extended, It takes more than 3 days for the 6mm thick sealant to fully cure.
Precautions: use as much as possible once after opening, once not used up, when used again, squeeze out the cured part, continue to use, does not affect normal use.
