VORAMER MS 7045 Polyol
PAPI™ 27 POLYMERIC MDI Isocyanate
Description VORAMER™ MS 7045 / PAPI™ 27 POLYMERIC MDI is a solvent free, two component polyurethane adhesive designed for the production of steel, aluminium, GRP or PVC faced sandwich panels with extruded or expanded polystyrene as in core insulation material.
This system has been especially developed for discontinuous panel production lines requiring an extended open time of 2 hours at 20°C.
It can be applied with low pressure, drip dispensing equipment or manually by spatula or roller.
