BLR/BLV
Tamper Evident Seal
BLR and BLV are single part, air-drying, tamper evident seals for screws, nuts, tuneable items and other
“factory fixed” components where evidence of unauthorised access is required. It is ideal for application onto
rotary controls to ensure that settings do not move under vibration loads, for example.
• One-part, fast drying tamper evident seal; available in red (BLR) or green (BLV) colours
• Ideal for sealing screws, nuts and tuneable items to show if changes to factory settings have occurred
• Provides good anti-fungal properties; resistant to mould growth
• Suitable for showing if settings have moved during transportation, etc.; ideal for rotary controls
Approvals RoHS-2 Compliant (2011/65/EU): Yes

Directions for Use
BLR/BLV should be applied directly onto the component with the brush contained in the lid of the bottle (15ml
sizes) or directly from the syringe (BLR10SL). It should be applied in an even film in sufficient quantity to be
easily visible. The coating will be tack free after 10 minutes but remains flexible for up to 24 hours. This is to
allow fine tuning. After this time the seal will become brittle and any interference or tampering will break the seal
and become self-evident.
BLR/BLV is usually removed mechanically, however it can also be removed or surfaces cleaned using
Electrolube Ultrasolve, ULS. Please check plastics compatibility prior to use.
