Harmonization Code : 3214.10.00 | Putty and other mastics | Resin cements, caulking compounds and other mastics
Main features
- 2.8 to 4.0 Pa s Melt Viscosity
- Flexibility to -35 deg C
- 23 kV/mm Dielectric Strength
Product Description
EUREMELT 3413 is a black copolyamide thermoplastic hot-melt adhesive supplied as granules for low-pressure injection molding around electrical and electronic devices. It combines a specified softening point of 150–160 °C with a specified melt-viscosity range of 2.8–4.0 Pa·s at 210 °C. The material is applied at 180–220 °C and provides flexible molded encapsulation, including low-temperature flexibility to −35 °C. It adheres to PVC and other plastics and is used where low-pressure molding must form a protective molded body around components, connectors, wiring, or related assemblies. Typical electrical properties include 23 kV/mm dielectric strength, 3 × 1012 Ω·cm specific resistance, and CTI 600.

Melt, inject, cool, and demold
The granulated material is thermally melted and injected around the electrical or electronic assembly using a low-pressure molding process. EUREMELT 3413 does not require reactive mixing or chemical cure; the molded part develops through cooling after injection.
