C-EP 3125A/B Technical Data Sheet
HEAT/CHEMICAL-RESISTANT ADHESIVE KAN抗熱/化學(xué)侵蝕膠粘劑
PRODUCT DESCRIPTION 產(chǎn)品介紹
C-EP 3125 is a two-component, room-temperature curing paste adhesive of high strength and toughness. It is Thixotropic with good environmental and excellent chemical resistance. Used for bonding electronic components, GRP structures, and most other items where a higher than normal temperature or more aggressive environment is to be encountered in service. C-EP 3125 是一種雙組分，高強(qiáng)度和韌性的室溫固化糊狀膠粘劑。它具有很高的觸變性并且具有極佳的環(huán)境和化學(xué)侵蝕抵抗性。C-EP 3125在用于粘結(jié)電子元件，玻璃增強(qiáng)纖維塑料結(jié)構(gòu)件和大多數(shù)其他組件中，將可抵抗更高的溫度和更惡劣的環(huán)境條件
