CATIONIC/DUAL CURE UV ADHESIVES

Novachem's range of Cationic and Dual Cure UV Adhesives has been developed for bonding applications where conventional UV curing may be restricted by shadowed areas, opaque substrates, or complex assembly geometries. These advanced adhesive systems combine the speed of UV curing with a secondary curing mechanism, ensuring complete polymerisation throughout the bond line.

Dual cure formulations typically utilise UV light for rapid fixture and handling strength, followed by moisture, heat, or anaerobic curing to achieve full cure in areas inaccessible to UV light. Cationic UV technology offers low shrinkage, excellent chemical resistance, superior adhesion to a wide range of substrates, and continued curing after exposure to UV energy.

These high-performance adhesives are widely used in electronics, medical devices, automotive components, optical assemblies, industrial manufacturing, and precision engineering applications where reliability and durability are critical.

Optimax^®Grade	Description	Viscosity	Shore Hardness
6439	UV structural adhesive offering multiple cure options – UV light, heat and activator. This offers advantages in bonding where the UV light will not reach and a secondary cure is required. Superior bond strength with a low shrinkage result, excellent flexibility and environmental resistance make it superior to other bonding adhesives.	1450	74D
6440	UV structural adhesive with a secondary anaerobic curing mechanism where light transmittance is difficult. Ideal for “shadow” cure applications, and also where a tough cured polymer and rapid cure speed is required. Can be used as an anaerobic adhesive and uncured fillets outside the bond line area can then cure with a UV light.	5000	78D

Applications for Cationic/Dual Cure Adhesives:

Electronics Assembly - ideal for bonding components where shadowed areas exist beneath housings, connectors, shields, and intricate assemblies. Provides rapid UV fixation with complete secondary curing throughout the assembled part.

Automotive Components - suitable for sensors, lighting systems, switch assemblies, and electronic modules where durable, vibration-resistant bonds are required.

Glass and Metal Bonding - provides excellent adhesion to glass, stainless steel, aluminium, and plated metals while maintaining long-term environmental resistance.

Optical and Precision Assemblies - low shrinkage characteristics minimise stress on delicate optical components, lenses, and precision-engineered parts.

Industrial Manufacturing - used in general assembly operations where fast production speeds and complete curing in difficult-to-access areas are essential.
