Material Notes:
Resinlab™ EP1056LC is a two part urethane modified epoxy adhesive designed to give good adhesion to metals and hard to bond surfaces such as PVC. It is thixotropic to provide good gap filling ability and prevent running and sagging during cure. It has very good resistance to water, acids and bases and most organic solvents. It was especially formulated to a 2A:1B mix ratio for use in automatic mixing equipment and dispensers with static mixers. EP1056LC will reach handle cure at room temperature within 8 – 16 hours. Cure time can be accelerated by the application of heat. Times and temperatures from 2 hours at 65°C to 10 minutes at 100°C are typical for most applications. Time to heat substrate must be taken into account. Cooler temperatures will also extend work time and increase cure times.Information Provided by Resinlab L.L.C., an Ellsworth Adhesives Company.
