Long-strip multi-gap resistive plate chamber (LMRPC) were built with (Module 1) or without (Module 2) adhesive tapes and silicones. Their performances were investigated by working gas mixtures of different gradient contents (Test 1: 94% freon, 5% iso-butane and 1% SF₆; Test 2: 90% freon, 5% iso-butane and 5% SF₆). Both the modules achieved 100% efficiency, with time resolutions of 75 and 70 ps. Comparatively, the Module 1 works with a lower applied HV at the higher noise level, and time resolution was not influenced greatly by the adhesive tapes and silicones.
