DYKEM® Cross Check Plus Skydrol®-Resistant Torque Seal® has been certified to meet the Boeing specification BMS8-45H Type I/III for a Skydrol-resistant, quick-dry tamper proof marker. This specification requires strict adherence to key performance properties such as dry-to-touch time, full cure time, Skydrol resistance, and dielectric strength, along with other critical physical, mechanical, and flammability requirements. Additionally, Organic Products F-925 continues to be referenced in Aircraft Maintenance Manuals and on many task cards as the required torque marking product to use in aviation applications. Because Organic Products is no longer operational, F-925 is no longer manufactured. With proven resistance to Skydrol PE-5 fluid, Cross Check Plus is the only direct substitute for F-925.
As the only fast-cure torque sealant with proven resistance to Skydrol PE-5 fluid, Cross Check Plus brings unsurpassed value to aircraft assembly processes as well as maintenance, repair and overhaul operations. The fluorescent colors are unique, providing enhanced visibility during inspection. Cross Check Plus remains the only offering in the market that carries a 2-year shelf life.
