查询经销商

单组分、透明、可以通过轻微加热加快湿气 RTV 固化、坚硬光滑的表面具有耐磨性、溶剂型（在许多区域挥发性有机化合物被免除）、UL 和军用规格、含有 UV 指示剂。

用途:

Conformal Coating suitable for protective coating for rigid and flexible circuit boards and for PCB system Printed Wiring Board (PWB) applications, particularly those requiring toughness and abrasion resistance.

优势:

Cures to a tough, elastoplastic, resilient, abrasion resistant surface
One-part Solvent-borne resin coating
Room temperature cure, no ovens required
Optional mild heat acceleration (after solvent flash-off) can speed in-line processing
UV indicator allows for automated inspection
UL 94 V-0 flammability rating
UL 746E / UL746C Recognized
IPC-CC-830, Amendment 1 Approved
Mil-I-46058C, Amendment 7 Approved
Good adhesion allows use with many low-solids (no clean) and no-lead solders
