Selector Guide for Radomes: JEC 2010

New Literature
TenCate Radome Selector Guide – TenCate has developed a new Radome Selector 
Guide which provides information for material and design engineers on TenCate’s line of 
cyanate ester and low dielectric epoxy prepreg resins and 
adhesives. The four-page guide provides a comparison of 
TenCate materials for high energy radomes used on 
commercial aircraft, shipboard radar, unmanned vehicles, 
satcom antennas and military aircraft radomes. The guide 
provides dielectric constant and loss tangent information on 
both neat resins and quartz laminates.  TenCate maintains 
separate carbon-free areas for the production of glass and 
quartz radome materials which is a critical factor in 
developing high purity non-conductive radomes.
Current Product Updates
RS-36 – TenCate is providing extended data on RS-36 which is currently in several 
structural satellite qualification programs. The new data provides both high modulus 
unidirectional and fabric data.  RS-36 is a high performance epoxy resin system with 
tailored properties for spacecraft and satellite usage including excellent thermal stability, 
low outgassing, enhanced chemical resistance and an excellent balance of properties 
under both autoclave and vacuum processing.  RS-36 is a cost effective alternative to 
cyanate ester resin systems usage on satellite structures. – TenCate’s newest 250°F/121°C cure ultra-low moisture cyanate ester prepreg 
resin will be the subject of a SAMPE paper in Seattle by ITT Geospatial Systems.
TC410 was developed for and qualified by ITT for use in satellite stable structures such as 
optical benches, reflectors and solar arrays.  The paper that will be presented is  titled “A 
Novel Cyanate Ester for Space Based Applications” by M. Rommel, C. Larsen, M. 
Drey, ITT Geospatial Systems - Rochester NY  and  F. Lee, K. Cao, Tencate Advanced 
Composites -  Morgan Hill CA.  A data sheet with high modulus fiber data can be found at:
