DELO Unveils Three Flexible Acrylate-based Sealants

Published on 2015-09-25. Author : SpecialChem

DELO, one of the world’s leading manufacturers of industrial adhesives for automotive, consumer and industrial electronics applications, now offers three highly flexible, acrylate-based sealants that can withstand temperatures up to 150°C and reach final strength within seconds of curing.


While DELO-PHOTOBOND GE4009 is a purely light-curing adhesive, well-suited for translucent materials, DELO-DUALBOND GE4707 and DELO-DUALBOND GE4906 use light-curing in conjunction with either heat or humidity, respectively. This dual method eliminates uncured adhesive in shadowed areas that may penetrate the components and cause corrosion at electrical contacts.

Ideal for sealing and casting small volume applications like relays, microswitches, connectors and pins as well as for fixing electronic components and bonding housing parts, these new temperature-resistant, tension-equalizing acrylates are particularly useful in the automotive industry.

DELO’s new light-curing adhesives offer universal adhesion to many substrates and are able to offer full leak-tightness after 300 thermal shock stress test cycles.

DELO-PHOTOBOND GE4009 has a viscosity of 1,600 mPas with a minimum curing time of 9 seconds. DELO-DUALBOND GE4707 is both a light- and heat-curing adhesive with a viscosity of 1,500 mPas and minimum curing time of 7 seconds. DELO-DUALBOND GE4906 is both light- and moisture- curing, has a viscosity of 2,200 mPas and a minimum curing time of 7 seconds.

Technical Specifications
• Highly flexible, leak-tight
• Temperature resistant from -40°C to +150°C
• Cures in seconds, short cycle time
