Hand Lay-Up epoxy resin system specially suitable for epoxy composites
Product Description
SWANCOR 2713- A/4BF is designed for the process of hand lay-up(15℃-20℃) which is composed of particular epoxy resin and hardener. t is especially good for application in yachts or large parts manufacturing. Their main characteristics are suitable viscosity, very short pot life, superior impregnation with glass fiber and carbon fiber.

Packing, Storage and Handling precaution
1. SWANCOR 2713- A packed in 265 gallon barrel, weight 1000 kg per barrel and55 gallon barrel, weight 200 kg per barrel and packed in 5gallon barrel, weight 20 kg per barrel
2. SWANCOR 2713-4BF packed in 265 gallon barrel, weight 900 kg per barrel and55 gallon barrel, weight 180 kg per barrel and packed in 2.5gallon barrel, weight 9kg per barrel.
3. The epoxy and hardener have to well mix by regular proportion for use.
4. After epoxy and hardener are mixed, it should be used in valid period, in case it gels and can't be use.
5. All implement for daubing and stowing should be cleansed right after used.
6. Under construction duration, should avoid skin contact, wear protective cloth and glove if necessary.
7. Crystallization will not occur above 15℃(59℉), if encounter, it can be undone by careful heating.
