Product Description

Synolite™ 8175-W-1 is a fire retardant unsaturated polyester resin, pre-accelerated, thixotropic, and filled. It is halogen-free, and components made with it feature excellent fire retardant, low smoke, and low toxicity properties.

Liquid Resin Typical Properties

Benefits

● Excellent fire retardant, low smoke, and low toxicity properties

● Good heat resistance

● Good mechanical properties

● Easy processing

Application

Synolite™ 8175-W-1 is designed for ease of fabrication using hand lay-up and filament winding techniques. It is recommended for building and construction, and for transportation fire retardant applications.

Processing Guidelines

● Condition the resin before use at a well-defined, application-dependent temperature (usually 15°C minimum for a MEKP/Co cure)

● Synolite™ 8175-W-1 contains cobalt accelerator; MEKP is the recommended peroxide — confirm the peroxide is within shelf life before use

● Maintain shop temperatures between 18°C and 32°C and humidity between 40% and 90% for consistent gel times

● Stir the product thoroughly before use; avoid styrene dilution to maintain fire retardant properties

● Fire resistance performance can be increased by adding 5–7% fire retardant to the resin

● Post-cure at elevated temperature (e.g. 80°C) for several hours to further optimize final cure state

Storage & Handling

Store indoors in the original, unopened, undamaged packaging, in a dry place at temperatures between 5°C and 30°C. Shelf life is reduced at higher temperatures, and resin properties may change during storage. Store in the dark, in 100% light-tight containers only.
