REL105
Low Styrene Emission Resin
1.When applying REL 105 resin, styrene emission is reduced by up to 50% compared to other general purpose resin.Emission is only 3-5% of polyester resins used compared to 6-10% of standard polyester resin.
2.Excellent glass fiber wet out properties and easiness of application is characteristic of REL 105.
REL 105 resin is recommended for spray-up,hand lay-up and filament winding methods for manufacturing numerous FRP products for the marine, building and construction and transportation markets.
