CHT Group AS1745T (ESP508) High strength adhesive
Categories:	Polymer; Adhesive
Material Notes:	AS1745T is part of the AS1740 range that comprises of: AS1740 – Liquid adhesive for shallow potting and coating AS1745T – High strength translucent, adhesive paste AS1745G – High strength, high temperature adhesive paste This is a specially formulated neutral cure silicone sealant specifically designed to meet the physical, chemical and temperature resistant requirements of MIL-A-46146B. It features exceptional physical properties and is compatible with many sensitive substrates including copper, brass, steel, aluminium and FR4, making this an ideal option for many electronic applications where high performance is paramount. It is described as an Alkoxy 1-part room temperature vulcanising (RTV) silicone sealant. The Alkoxy cure system produces a silicone sealant with excellent adhesion to most common substrates Key Features: Meets the physical and chemical requirements of MIL A- 46146B High strength Non corrosive Adhesion to many substrates Typical Applications: Assembly of electrical and electronic equipment Sealing and bonding of corrosion sensitive devices Shallow encapsulation of small circuits and connectors Formerly Amber Chemical Co (ACC Silicones), aquired by CHT in 2017
