Product Description

Atlac® 580 is a high-grade bisphenol A vinyl ester urethane resin combining exceptional chemical resistance with an outstanding balance of heat resistance and flexibility. It is especially resistant to alkaline media and hot water, and offers very good handling and curing properties. Components based on Atlac® 580 handle well with carbon, aramid, or glass fiber to make strong, durable parts.

Need a version purpose-built for hand lay-up and spray-up only, with enhanced thixotropy for inclined-mold work? See Atlac® 580 ACT.

Benefits

● No-foaming curing system, even with standard MEKP

Liquid Resin Typical Properties

Application

Atlac® 580 can be used in all fabrication methods, and is especially adapted to filament winding, centrifugal casting, pultrusion, hand lay-up, and spray-up. Extra styrene addition lowers viscosity for resin injection molding techniques. It may also be formulated for mortars, floor toppings, and lining systems based on flake glass or mica, and can be used as a gelcoat base resin and laminating resin for marine applications.
