- Low viscosity, better coloring and thickening property.
- High gloss.excellent water and heat resistance.
- High physical properties.
Application
- Low shrinkage additive formulations for S/BMC.
- Electrical appliances,sanitary ,industrial parts,water tanks and auto motive parts etc.
Package
220kg or 1100kg
 

Shelf life
- 3months under 25ºC,away from  heat sources, direct sunlight or steam pipes,rain etc.
- Keep sealed to prevent moisture pick-up and monomer loss.

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.
