thermal grease for cpu

Description:

 

ZR340 silicone compound  is a room temperature/heating curing and molding organic silicone materials. This kind of two-component elastic silicone potting, designed to protect in harsh conditions of electronic products.

ZR340 organic silicon encapsulating glue used new technology without heating , would be curing. When used according to 1:1 (weight ratio or the volume in the thorough mixing proportion of A and B two components, products will be in A certain time, form of the elasticity of curing buffer material.

 

After curing glue has the following characteristics:

 

uAgainst moisture, dirt and other atmospheric composition

uRelieve mechanical, thermal shock and vibration of mechanical stress and tension caused

uEasy to repair

uHigh frequency electric performance

uNo solvents, no cure by-products

uHave stable mechanical and electrical properties between -50°C-200°C

uExcellent flame retardancy

Operation time is a quantity of cement with 100 g.

 

A, B two components in proportion to remove, stir to mix evenly, vacuum suction bubbles in operation period, remove the need of the potting casting products, if the potting product is too big, can divide times, then potting according to (60 °C / 30 min or 25 °C / 10 hr) can be cured.

 

Operation caution:

 

uAgent A place for a long time, maybe produce precipitation, mix part A and B access should be paid attention to save after sealing.

uMixing should pay attention to the same direction, otherwise, it will stir with too much bubble; Borders and the bottom of the container sizing material should also stir well, can appear otherwise stir caused by uneven local not curing phenomenon.

uCasting the product vacuum pumping, remove again bubble can improve after curing products comprehensive performance.

uTemperature is too low will lead to curing speed partial slow, heat cure advice; Potting thickness more than 2 cm above 80 °C not directly in the curing, lest cause explosive together.

uZR340 with contain N, S, P element of compounds and some heavy metal ion compounds, will appear difficult contact curing or not curing phenomenon. These heavy metal ions including Sn, Pb, Hg, Bi, As, etc.
