Vinyl ester resin
Product Description
Vinyl ester resin Description
- Two versions.Bisphenol-A and Novolac epoxy modified vinylester resin.
- Medium viscosity, medium reactivity,
- Lighter color, with less foaming effect during the cure.
- Controlled exothermic peak.
- Good chemical and water resistance.
- Has promoted and thixotropic version.
- Has closed molding version.
- Has CIPP and tooling Gel coat base version.
Vinyl ester resin Application
- Hand lay up , spray up process, Filament winding, pul trusion,closed molding etc.
- Industrial parts with high chemical resistance, Pipes, tanks, containers etc.
Vinyl ester resin Package
- 200kg or 1000kg
Vinyl ester resin Shelf Life
- 6months for un-promoted or 3months for promoted under 25ºC,away from heat sources, direct sunlight or steam pipes,rain etc.
- Keep sealed to prevent moisture pick-up and monomer loss.
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.
