Laboratory Facilities

Adherent Laboratories has a fully equipped adhesives and materials laboratory of its own and with its strategic partnerships with other research, educational, and testing laboratories Adherent's capabilities rival that of any major adhesive company.  Our capabilities include:

Analytical

• Complete adhesive analysis (qualitative or quantitative)
• AA, TGA, TMA, NMR, DMA, FTIR, DSC, GPC, ...
• Electron microscopy
• Flavor, odor and sensory analysis

Physical and Material Testing

• Instron tensile and compression testing
• Rheology (oscillatory, capillary, Brookfield)
• Gardner and Hunter Colors

General Adhesives Testing

• Viscosity
• Heat resistance (SAFT, PAFT, IOPP)
• Thermal stability
• Mettler Softening Point
• Needle Penetration
• Adhesion testing (various substrates and temperatures)
• Open time and set time

Nonwoven Diapers

• Initial and aged T-Peels to PE/NW
• Aged color and odor testing
• Bleed through
• Application sprayability
• Elastic leg and waist band creep resistance and adhesion

Pressure Sensitive Adhesives

• Peel adhesion (180 degree, 90 degree, various rates, temperatures, and substrates)
• Static, isothermal creep (various temperatures)
• Programmed temperature creep (SAFT)
• Tack (rolling ball, probe, loop)

Pressure sensitives

• 180 peel
