Rapidstick™ 8-7400 Tamper Evident Ink/Varnish Seal
Rapidstick™ 8-7400 Tamper Evident Ink/Varnish Seal is a red, solvent-based marking seal for electronic tuneable items, factory fixed components, screws, nuts, and other applications where evidence of unauthorised tampering or access is visibly required. It is water and moisture resistant and offers excellent flexibility.
8-7400 is ideal for tamper-proofing rotary controls to ensure that pre-set or tested parameters do not move under vibration or accidental drop.

Chemicals, Lubricants & AdhesivesCHEMTOOLS Rapidstick™ Surface Mount Epoxy (Red)
Rapidstick™ Surface Mount Epoxy is an easy-to-use one-part epoxy adhesive, specially designed for electronic assemblies. It bonds surfaces of mounted devices to printed circuit boards prior to double-sided reflow or wave solder assembly, and is ideally suited to printing a range of dot heights with one stencil thickness, and where high wet strength characteristics and high print speeds are necessary.
Surface Mount Epoxy has rapid thermal cure properties, robust handling characteristics, and is formulated to resist shear thinning. The viscosity and surface tension prove ideal for high speed placement equipment.
SME offers excellent adhesion to metal, ceramics, and glass-filled epoxy surfaces, and is suitable for all open squeegee and enclosed head stencil printing systems.
