Pre-accelerated, resilient, low profile vinyl ester hybrid resin, specially formulated for applications requiring superior osmosis resistance, good toughness and improved cure. DEXATMGUARD 5101 PA has good low shrink properties and therefore reduces the likelihood of print through, along with low viscosity affording rapid wet out of reinforcements. A futher advantage of this resin is that, being pre-accelerated, only a suitable catalyst is required to initiate the curing process. DEXATMGUARD 5101 PA has been specifically designed for infusion/RTM processes and is especially suitable for marine applications.
