Adhesives & Sealants
Ester gums and rosin esters for hot-melt, pressure-sensitive and tape-label adhesives, plus polyamide hardeners for epoxy adhesive systems.
Most adhesive systems start with tack and compatibility. Unigum ester gums and UMaleic SS rosin esters support the pressure-sensitive, hot-melt and tape-label adhesive systems we supply.

What to think about
Pick softening point by use
PSA uses lower-melt E-90; hot-melt and tape applications lean on E-105.
Colour matters for clear adhesives
Unigum grades remain under Gardner 2, suitable for transparent tape work.
Epoxy adhesives
Unimide 115 brings high-build, flexible epoxy adhesive performance with a forgiving cure profile.
Tape-label adhesive standardised on E-105 and a secondary tackifier blend.
A label converter rebuilt its tape adhesive using Unigum E-105 as the primary tackifier. The higher softening point improved thermal stability versus older E-95-based formulations during warehouse storage.
