KE40RTV
Product Information
UL 94V-0 ratingLow corrosion
Low odour
Excellent adhesion to many sub straights
Excellent heat and flame resistance
Flowable or thixotropic
Shin-Etsu KE-40RTV silicone is UL 94V-0 rated neutral curing, adhesive/sealant applications in consumer electronics, transportation and aerospace where outstanding flame resistance is required. KE-40RTV Grey meets the requirements of AMS 3374 as a fire wall sealant.
KE-40RTV adhesive/sealant is a non-sag, thixotropic material that may be applied overhead or on sidewall joints and surfaces.
KE-40RTV cures to a tough, flexible silicone rubber elastomer upon exposure to atmospheric moisture at room temperature. These adhesives/sealants exhibit excellent adhesion to many substrates, including glass, wood, ceramics, clean metals, epoxy composites, other silicone elastomers and plastics like ABS, polycarbonate, and PVC.
This product is UL registered. A brief description of UL 94 Flammability Rating can be found here
