Product Description

Closed Molding Resins(Unsaturated Polyester /Vinyl Ester Resin)

Product Description

Closed Molding Resins Application Attention

- Strong recommended that gel time should be checked in the customer's plant, as storage, temperature, humidity and catalyst will produce different gel time from that mentioned. The catalyst level should not exceed 2.0 % or fall down below 1.0 % for proper cure. Recommended range is within 1.0 % ~ 2.0 % at 25ºC being ideal. This product should not be used when temperature is below 15ºC, as curing may be adversely affected.

Closed Molding Resins Shelf life

3 months when stored in original sealed containers below 25ºC, away from direct heat, sunlight and rain.

Closed Molding Resins 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.
