4. Thermal performance (2mm film thickness)
The lower limit of using temperature is ……… To 60℃(brittle point)
Maximum temperature for continuous use …………………+ 150℃
(Maximum temperature at 1000h)
Maximum instantaneous service temperature …………… . + 185℃
(Maximum temperature at 72h)
Note: Mechanical properties and Shore hardness A were measured before and after thermal aging. These service temperatures are not absolute limits; they represent the temperature range at which the mechanical properties are reduced to more than 50% of the initial value. If not continuous 72 hours, instantaneous can withstand higher temperatures.
5. Adhesive performance
After 14 days of curing at 23℃×50%RH, the shear strength of 1mm specimen thickness at the joint was obtained according to the standard NM748.

This product can also be a bottomless coating bonding a variety of substrates such as: enamel, spray steel, cast iron, and are 100% cohesive destruction.
Product process
This product can be "ready to use", so the use process is relatively simple. It can be operated manually or automatically by equipment.
The product is applied to one of the two joint surfaces to be bonded before the skin is formed.
It is recommended to apply this product on a clean and dry surface. Do not apply immediate pressure to the joint.
