Adhesive Systems RP 45 Low-Viscosity Cyanoacrylate Adhesive

Description

RP 45 adhesive is a low-viscosity cyanoacrylate for fast fixture work on similar and dissimilar materials. Chemical Concepts lists handling strength in 5 to 10 seconds, and the technical data sheet calls out clear color, 45 cP viscosity, and ethyl chemistry for assembly, maintenance, and repair jobs that need a quick set without mixing.

RP 45 Adhesive Benefits

• Low viscosity helps the adhesive wet close-fitting parts and narrow bond lines.
• Fast fixture time keeps bench assembly, small part work, and repair flow moving.
• Clear cured appearance is useful where bond lines should stay less visible.
• Ethyl cyanoacrylate chemistry fits many day-to-day bonding tasks across plastics, rubber, and metal.
• Post-application capability helps when the joint cannot be fully coated before the parts come together.

This grade fits shops that bond ABS, PVC, polycarbonate, phenolic, neoprene, steel, aluminum, wood, and leather in short-cycle work. The RP 45 data sheet also lists electrical properties and solvent-resistance retention figures, which makes it useful for light industrial builds where operators want a straightforward instant adhesive and do not need a paste or gap-filling gel.

RP 45 Adhesive Applications

• Bonding plastic housings, trim pieces, and molded components.
• General repair of rubber, leather, and mixed-material parts.
• Small metal-to-metal or metal-to-plastic assemblies with close fit.
• Bench work where quick handling strength matters more than long open time.
• Production support jobs that need a clear instant adhesive kept ready at the station.

For best results, parts should be clean and free from contamination on the bonding surface. The technical data sheet notes that thin bond lines cure faster, while larger gaps lengthen cure speed. When parts do not mate flush, the sheet recommends moving to a higher-viscosity product rather than forcing this grade to bridge a gap it was not built to fill.
