Vinyl ester resin curing temperature.

About vinyl ester resins. Vinyl ester falls between polyester and epoxy on price most physical. Mixing the correct ratio of a b is extremely important. Previous work has shown that higher catalyst levels yield a higher degree of cure for thin panels made at 77 f 25 c.

Although the curing extent was observed increase with increasing the operating temperature the study of residual heat of cured vers indicated that the final. Typical temperatures of the so called hot curing process are 120 c up to 160 c. It has a measured glass transition temperature t g of 110 c hence allowing the clamp to withstand up to a maximum service temperature of 80 c. These temperatures are necessary to achieve a reasonable degree of curing within a short time.

Like polyester resins they require mekp as a catalyst to cure or harden. As with all polyesters rate and degree of cure are functions of catalyst concentration and of temperature. It is uv resistant which reduces yellowing and surface degradation from uv exposure. However the aging of the ve resin post cured at 100 and 140 c does not change the chemical structure of ve resin as the aging is produced above the post curing temperature.

Vinyl ester resin is selected due to its well known performance in marine conditions and good chemical resistance to a wide range of chemicals including sour crude up to 100 c. Resin will typically not cure well in temperatures below sixty degrees and will cure too fast in temperatures above 90 degrees. This is oversimplified but it does help convey the qualities of the resin. Complete cure of a resin is critical to achieving the optimum corrosion resistance and physical proper ties of a laminate.

It is ideal to work in temperatures around 77 degrees. The effects of isothermal temperature on the curing extent gel time dynamic rheological behaviors and mechanical properties of vinyl ester resins vers were systematically studied. Handling tap marine vinyl ester resins are pre promoted to cure at room temperature upon adding tap mekp catalyst. Curing without addition of accelerators requires temperatures within the parts to be cured from approx.

The cure time and pot life will depend on the initiator system its concentration as well as on the type of resin and vinyl monomer and cure temperature. The post cure at 60 c of the ve resin cured at 25 c also produces additional post curing and hydrolytic degradation because of the aging temperature is above the post curing temperature. Vinyl ester resins are often considered a cross between polyester resins and epoxy resins. Resin products with an activator are typically two pack systems whereas heat curable vers are typically one part systems.
