New 100 Solids Acrylated Allophanate Oligomers Offer Low Viscosity and High Functionality while Maximizing UV Coating System Performance

摘要

The coatings industry's desire for 100% solids, low viscosity, high functionality and exterior performance has resulted in a new class of oligomers based on acrylated allophanates. These new polyurethane products offer viscosities in ranges from 8,000 -60,000 cPs, functionalities as high as 4, T_g's from 30-80 °C and pendulum hardness values from 60-180 seconds. This unique class of oligomers gives UV formulators the ability to minimize the amount of acrylated monomer and maximize coating performance.
