Corrosion-Resistant Vinyl Ester Resin

What Is #1110 Vinyl Ester Resin?

#1110 Vinyl Ester Resin is a corrosion resistant laminating resin formulated for maximum resistance to most fuels, vapors, and both acidic and basic chemicals. Vinyl ester sits between polyester and epoxy in the resin family, with handling characteristics, properties, and price that generally fall between the two systems.

#1110 Vinyl Ester Resin is heat resistant, blended for toughness, and has a low viscosity that suits resin infusion in addition to hand lay-up and spray applications. The raw materials used to manufacture #1110 are listed as acceptable under FDA regulation Title 21 CFR 177.2420 for repeated use in contact with food.

Why Choose #1110 Vinyl Ester Resin Over Polyester or Epoxy?

Polyester is the most widely used resin in composites because it is economical, fast curing, and naturally UV resistant, but it does not offer the corrosion resistance that vinyl ester provides. Epoxy delivers the highest strength and adhesion but costs more and is less forgiving to mix.

#1110 Vinyl Ester Resin bridges that gap, providing excellent corrosion and abrasion resistance along with strong impact strength and high tensile elongation, which lets it withstand impacts and repeated flexing without developing cracks. When a project needs better chemical resistance than polyester can give without stepping up to the cost of epoxy, #1110 is the practical middle ground.

What Are the Best Applications for #1110 Vinyl Ester Resin?

Fibre Glast recommends #1110 Vinyl Ester Resin for heavily corrosive environments. Typical uses include repairing tank linings, addressing blistering boat hulls, building and repairing chemical storage tanks, and fabricating tough all-around parts that must flex and absorb impact. The low viscosity of #1110 also makes it a strong candidate for vacuum infusion work where the resin must flow easily through the reinforcement.

How Should #1110 Vinyl Ester Resin Be Used for Best Results?

#1110 Vinyl Ester Resin is formulated for 1.25% MEKP catalyzation and can be purchased alone or as part of a Resin and Hardener Kit that pairs the resin with #69-A catalyst. Because vinyl ester shares a styrene chemistry with polyester, the same care with mixing and ambient temperature applies. Shelf life is limited to three months, so order to match the pace of your project rather than stocking far ahead.
