High rwb thaiv tsev Polyurethane Potting Adhesive rau hluav taws xob tiv thaiv
Khoom Description
cov khoom siv yog yooj yim los lis thiab ua tau raws li ib puag ncig tus qauv. Cov nplaum txheej zoo li grey nrog me ntsis hardness, muab zoo heev waterproofing thiab rwb thaiv tsev zog. Nws yog qhov zoo tagnrho rau kev sib khi cov khoom siv hluav taws xob hauv ib puag ncig nrog kev vibration, av noo, lossis muaj zog corrosive, muab kev poob siab, kev tiv thaiv noo noo, rwb thaiv tsev, thiab corrosion kuj. Nws daim ntawv thov tseem ceeb yog sealing cov khoom siv hluav taws xob ntawm PCB boards.
