Orca 301 is a superior grade isophthalic laminating resin. This resin is used in the same applications as ortho resin but where improved physical properties are desired (ie better bonding, more impermeability to moisture, better tensile strength etc.). It cures with a surface tack for better bonding between layers. Because of the surface tack there is no need for sanding between layers.
