Isophthalic Synolite 3720-L-1 Resin x 25kg
£99.50
Chemical/physical nature
Synolite 3720-L-1 is formulated for hand lay-up and spray-up applications. The thixotropic nature of the resin allows application on vertical parts without the risk of sagging or drainage.
Principal properties
Synolite 3720-L-1 is an unsaturated, isophthalic based polyester resin, diluted in styrene. This resin is thixotropic and pre-accelerated.

Guidelines before use
Before use, the resin should be conditioned at a well defined, application dependent temperature (usually15°C minimum for a MEKP / Co cure). Ensure the product is thoroughly stirred before use.
Storage guidelines
The resin should be stored in the original, unopened and undamaged packaging, in a dry place at temperatures between 5°C and 30°C. Shelf life is reduced at higher temperatures. The shelf life of styrene containing unsaturated polyesters will be significantly reduced when exposed to sunlight. Store in dark and in 100% light tight containers only.
