This product must be used at workshop temperature between 15 and 30°C.

No dilution is requested, only add the catalyst.

Catalyze: between 1.0 and 2.0 % of MEKP 50, according to the requested thickness and production cycle.

Homogenize the product before use.
Stop mixing before projection.
Check machine cleanness.
FSP-BC 1102 should be used on polymerized gelcoat “tacky”. Check that the product color changes after having catalyzed. Spray FSP-BC 1102 at about 70-80 cm from the support. Check regularly the sprayed thickness with a thickness gauge. The coat must be 500 to 800 microns.

Spray by doing crossed passes.

  • Much less water penetration than with a skin coat ( thin mat with only resin )
  • Catalyst revelator
  • Good thixotropy, enabling to apply 600 microns in verticalwithout sagging.
  • Easy to use.
  • Reduces fiber marking
  • Improves osmosis resistance
  • Reduces porosity risks
  • Reduces pre-release risks
  • Eliminate risks of elephant skin

Storage Condition

Product should be kept away from direct sunshine and at temperature below 20°C. Under these conditions, the product will keep its properties 4 months from production date.
