Filament winding resin - Food Grade Winding Resin WD896/9306S

 

● Properties:

WD896/9306S unsaturated polyester resin is a type of orthophthalic resin , mainly composed of phthalic anhydride, maleic anhydride and standard diol. It is soluble in cross-linking monomers such as styrene and has medium viscosity and moderate reactivity.

 

● Performance and Application:

WD896/9306S accord with GB13115-1991 demand,it is orthophthalic foodstuff-class resin,high strength and good toughness,higher elongation at break,suitable for lining layer of pipe and tank required foodstuff certificate.

Accord with unsaturated polyester resin for mechanically transformed filber reinforced plastics JC/T1092-2008 stander,it can use for filament winding process.

 ● Instruction:

1.WD896/9306S resin without wax, promoter and thixotropic agent.

2.Accord with GB13115-1991 stander,when making food grade FRP products,the dosage of promoter and curing agent must required to fulfill below requirements:

Tertiary amine ≤0.1%

Cobalt Octoate or cobalt naphthenate  ≤0.03%

Peroxide  ≤3.0%

3.Accord with GB13115-1991 stander, the food grade FRP products post curing executes the following processes of:

80℃ Post Curing 3-4 hours, and washing 1-2hours with 80℃ hot water.

4.It is recommended chose Neweco 9406S which is the type of isophthalic food grade resin,if you have higher requitment for heat resistance and elongation at break.

5.It is recommended Neweco 9365 resin for the structural layer of winding pipe and tank.
