Optimax® Wire Tacking UV Adhesives for Precision Electronics Assembly

Overview

Optimax® wire tacking UV adhesives are fast-curing, light-activated adhesives designed to secure fine wires and delicate components in place during electronics assembly. As electronics manufacturing moves toward miniaturisation and higher component densities, the need for a controlled, instant-tack solution has never been greater. These adhesives allow manufacturers to achieve high precision on PCBs, sensors, and micro-electronic devices without thermal stress or mechanical distortion.

UV curing ensures rapid processing while maintaining the integrity of sensitive components. Optimax® wire tacking adhesives provide a fast, controlled, non-conductive tack that enables automation, reduces rework, and increases line output by stabilising components long enough for downstream processing — including soldering, overmoulding, and final cure.

Novachem supplies these adhesives to electronics manufacturers across the UK and EU who demand speed, reliability, and process efficiency.

Key Benefits

Instant cure in seconds under UV/LED exposure
Precise placement with minimal spreading or slump
Strong adhesion to metals, plastics, and PCB substrates
Compatible with automated dispensing systems
Non-conductive — safe for use directly on live circuit areas
Low exotherm — no heat damage to sensitive components
RoHS and REACH compliant for UK and EU manufacturing

Applications

PCB assembly and prototyping
Sensor and micro-electronic assembly
Automotive wiring harnesses
Aerospace electronics
Medical devices — wire leads in probes and sensors
Industrial electrical and sensor assemblies

Selecting the Right Grade

When specifying a wire tacking adhesive, key parameters to assess include viscosity relative to wire gauge and spacing, UV light accessibility to all bond lines, whether reworkability is required at a later assembly stage, and the thermal and chemical environment the cured assembly will encounter. Novachem's technical team can assist with grade selection based on your specific substrate and process requirements.

Process Integration

Optimax® wire tacking adhesives are engineered for compatibility with automated dispensing equipment. Low-viscosity grades work with pneumatic dispensers and dispensing pens, while higher-viscosity options suit manual or semi-automated application. UV or LED curing stations can be integrated inline for high-throughput production.
