WEICON Threadlocking Varnish red RAL 3000, 30 g, security lacquer for threads, fast-drying, non-conductive
0
Description
WEICON Threadlocking Varnish in red (RAL 3000), 30 g, is a fast-drying, non-conductive security lacquer for marking and tamper-evident sealing of threaded joints and adjustable components. It forms a durable, matte coating with excellent adhesion on many substrates and resists water, fuels, mineral/paraffin oils and diluted acids/alkalis—perfect for quality control and service inspections.
Benefits & key features
- Fast drying and easy application—speedy assembly checks.
- Non-conductive, matte film with high adhesion.
- Chemical resistance to water, fuels/gasoline, mineral & paraffin oils, diluted acids and alkalis.
- High-visibility red colour for sealing and marking (RAL 3000).
- Tamper-evident protection and support against self-loosening.
Properties & applications
- Quality control & service: clear “seal” on bolts, nuts and adjustment points.
- Corrosion protection: barrier coating limiting environmental contact.
- Tamper evidence: immediate detection of adjustments or misuse.
- Broad substrate compatibility: metals and common engineering materials.
