Product Details
Product Description
DM-HT718 RTV silicone sealant （high temperature resistant to 300℃）
DM-HT718 is a condensation-type one-component room temperature vulcanized silicone rubber,
The condensation reaction with moisture in the air releases low molecular weight to cause cross-linking, and then solidifies into a high-performance elastomer
Precautions
A small amount of solidification may appear at the mouth of the nozzle during use, and it can be used normally after being removed without affecting product performance;
After the operation is completed, the unused glue should be tightened immediately and the cap should be sealed and stored;
There is a slight irritating smell released during the curing process, pay attention to the ventilation of the working area.

Product Applications
Application area
High-strength bonding of metal, glass, plastic, ceramics, rubber, etc.
Adhesion and sealing of household appliances, kitchen appliances, instruments and meters, electronic appliances and other industries.
A variety of applications that require bonding or sealing in other industries.
Application tips
The bonded surface must be clean, dry and free of putty before bonding.
Substrates that may seep out of oil are not suitable for direct application of sealant.
For rusted or corroded metal surfaces (such as aluminum oxide, copper, iron oxide rust surface), in order to ensure the bonding effect, the rust on the surface layer needs to be worn off before coating.
Due to the construction environment, construction methods, and material differences, pre-testing is required before use to ensure adhesion performance.
The optimal coating temperature is +5 ~ +40°C. When the temperature is low, the extrusion resistance
