Vinyl ester falls between polyester and epoxy on price most physical.

Vinyl ester resin curing temperature.

Resin and work area should be between 24 c 75 f and 35 c 95 f to ensure satisfactory results. Although the curing extent was observed increase with increasing the operating temperature the study of residual heat of cured vers indicated that the final. These temperatures are necessary to achieve a reasonable degree of curing within a short time. Mixing the correct ratio of a b is extremely important.

The most common vinyl monomer is styrene. Polymer chemistry curing ve resin 10 accelerator 553s in vinyl ester resin epoxy based vinyl ester 100 100 butanox m 50 phr 2 2 accelerator nl 51p 6 co soln phr 0 5 accelerator 553s 0 5 gassing geltime in pure resin min yes 60 no 60 cobalt content mg kg 300 100 time to peak min 113 108 peak exotherm c 44 61 barcol hardness. Curing without addition of accelerators requires temperatures within the parts to be cured from approx. 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.

As with all polyesters rate and degree of cure are functions of catalyst concentration and of temperature. Typical composites are made in thicknesses ranging from 0 005 in. 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. It is ideal to work in temperatures around 77 degrees.

It is uv resistant which reduces yellowing and surface degradation from uv exposure. Resin will typically not cure well in temperatures below sixty degrees and will cure too fast in temperatures above 90 degrees. About vinyl ester resins. 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.

Handling tap marine vinyl ester resins are pre promoted to cure at room temperature upon adding tap mekp catalyst. Resin products with an activator are typically two pack systems whereas heat curable vers are typically one part systems. 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. Like polyester resins they require mekp as a catalyst to cure or harden.

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. Vinyl ester resins are often considered a cross between polyester resins and epoxy resins. Complete cure of a resin is critical to achieving the optimum corrosion resistance and physical proper ties of a laminate. 0 13 mm to 0 400 in.

Previous work has shown that higher catalyst levels yield a higher degree of cure for thin panels made at 77 f 25 c.
