Vinyl ester resin Safety Attention
- Resin solutions contain volatile and flammable monomers such as styrene(flash point : 31ºC)
- The resin should be handled and used in well ventilated, flame proof areas
- To wear gloves and goggles to guard against any skin/ eye irritation arising from the presence of styrene. Under no circumstances must accelerators be mixed with peroxide catalysts as it can cause explosions.
- Transportation should according to the State Council "Chemistry Dangerous Articles Safety Management Regulations" due to it contains styrene monomer.
inflammable.
