Description
Adhesive Systems RP 4000 is a high-viscosity, rapid-curing cyanoacrylate adhesive built for bonding a wide range of similar and dissimilar substrates. It reaches handling strength in 15 seconds on most material combinations, which keeps assembly-line cycle times short. The formulation meets MIL-SPEC A 46050C Type II Class 3 for industrial use.
Where Adhesive Systems RP 4000 earns its place
The high viscosity grade resists run-off on vertical surfaces and gap-fills small irregularities better than thin-grade cyanoacrylates. Common substrate combinations include rubber to metal, ABS to PVC, neoprene seals, and small assembly bonds on plastic housings. The cure speed makes it well suited to fixturing operations where a temporary hold replaces a clamp.
How the adhesive performs
Tack happens in seconds against most porous and non-porous substrates with light pressure applied. Full handling strength follows within 15 seconds on representative substrates, and full cure builds over the next several hours. Working tolerance is small (use thin films), and bond performance depends on clean dry mating surfaces. Avoid moisture-laden parts.
