116-04A / B-187極導(dǎo)熱環(huán)氧灌封料

說明：116-04A是一種氮化物填充的雙組分環(huán)氧灌封和封裝化合物。產(chǎn)品是

設(shè)計用于在固化過程中迅速釋放滯留空氣，從而形成光滑、無針孔的表面。使用B-187時

希望使用壽命長，耐熱性高。116-04A是F940A更導(dǎo)熱的版本。

116-04A / B-187極導(dǎo)熱環(huán)氧灌封料

116-04A / B-187
EXTREMELY THERMALLY CONDUCTIVE, EPOXY POTTING COMPOUND
DESCRIPTION: 116-04A is a nitride filled, two component, epoxy potting and encapsulating compound. Product is
designed to release entrapped air rapidly during cure, resulting in a smooth, pinhole free surface. Use B-187 when
long pot life and higher heat resistance is desired. 116-04A is a more thermally conductive version of F940A.

Part A Part B-187 Mixture
Appearance: Grey Amber Grey
Viscosity (cps): 3600 500 3100
Mix Ratio (By Weight): 100 3 ----
 Pot Life: ---- ---- > 4 Hrs
MIXING INSTRUCTIONS: Premix Part A in original container prior to adding curing agent. Add Part B to Part A
and mix until uniform. Use with Part B-187 when high temperature performance is desired. NOTE: It is not
unusual for crystallization of the B-187 to occur. Warm to 40-45°C in a water bath to return the material to it's
original viscosity. The crystallization of the catalyst does not affect the performance of the product in any way. To
prevent re-crystallization, store the B-187 at temperatures between 35-45°C.
