TYPICAL CURING PERFORMANCE

Under normal conditions, the atmospheric moisture initiates the

curing process. Although full functional strength is developed

in a relatively short time, curing continues for at least 24 hours

before full chemical/solvent resistance is developed.

Cure Speed vs. Substrate

The rate of cure will depend on the substrate used. The table

below shows the fixture time achieved on different materials

at 22 °C / 50 % relative humidity. This is defined as the time to

develop a shear strength of 0.1 N/mm².

Fixture Time, seconds:

Mild Steel (degreased) 50 to 100

Aluminum (degreased) 15 to 40

Zinc dichromate 50 to 150

Neoprene <20

Rubber, nitrile <20

ABS 30 to 60

PVC 50 to 100

Polycarbonate 50 to 100

Phenolic 20 to 50

Cure Speed vs. Humidity

The rate of cure will depend on the ambient relative humidity.
