About Aropol M 105 TBR Lloyd’s Approved Resin

Aropol M 105 TBR is a polyester resin with low styrene emissions and is manufactured by a well-respected composites manufacturer, Ashland.

It is an unsaturated polyester resin based on an orthophthalic acid.

This resin is approved by Lloyd’s register meaning it is suitable for use in the construction of boats.

It also complies with the requirements of ISO 12215-1 which is the industry standard for the construction of small crafts.

In terms of styrene emission, this resin performs very well when compared to many standard polyester resins. Styrene emission when using this resin is reduced by up to 50%.

Emission testing on the Aropol M 105 TBR is 2-5% of polyester resin usage. Standard polyester resins may have up to 5-10% emission rates.

Another benefit of this resin is its fast wet-out properties. It is also very easy to work with.

Aropol M 105 TBR polyester resin is pre-accelerated and only requires a catalyst to start the curing process. Metox catalysts would be the standard range of hardeners used with this resin.
