Description

VESTALITE® P 311 is a polyurethane based resin formulation specially designed as matrix for fast curing prepreg applications. It gives room temperature stable, dry and non-tacky prepregs, which can be formed thermoplastically at 70 - 100°C and cured at temperatures between 150 and 180°C.

This material data has been provided by Evonik Industries AG.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
