TECHNICAL DATA SHEET
POLYEURO MH-752HH
®
Two Component Aromatic Hybrid
Polyurethane Protective Coating

Product Description
Polyeuro MH-752HH is a fast set, rapid curing, aromatic, two Technical Data (Based on Draw Down Film)

component, hybrid polyurea/polyurethane spray designed Mix Ratio by Volume 1A : 1B
to be applied over EPS, wood, and many other surfaces with Pot Life @ 150ºF (65.5ºC), 50% R.H. 2-4 seconds
better heat stability and greater stiffness. Its excellent balance
of stiffness and impact resistance provides excellent plastic Tack Free Time (thickness & substrate 60-120 seconds
“shell-like” protection for delicate foams and EPS. Polyeuro temperature dependent)
