Product Description

Product Description

8505 resin is a highly active m-phenylene neopentyl glycol unsaturated polyester resin with excellent mechanical properties, high elastic elongation, excellent crack resistance, excellent wettability and heat resistance and chemical resistance.
It is especially recommended for glass fiber reinforced plastic products, high-grade artificial stone products and gel coat substrates that require good water and corrosion resistance.

Transportation and storage

It is highly recommended to store the resin in a room below 25ºC to avoid direct sunlight. Exceeding the storage conditions will affect the resin properties such as viscosity and gel time. The resin should be mixed thoroughly before use. Keep the barrel sealed to prevent moisture from entering, and tighten the lid.

If the ingredients in the resin are used improperly, it will cause injury. Avoid contact with skin and eyes.

Wear necessary protective equipment and clothing when using it.
