Vinyl Esters Products

Vinyl esters shrink less on curing which means that pre release of a laminate from a mold is less significant.

Vinyl esters products. Vinyl ester resin or often just vinyl ester is a resin produced by the esterification of an epoxy resin with acrylic or methacrylic acids. See our vinyl ester primer brochure and right choice brochure for more details on what product is right. Vinyl acetate is not as hydrolytically stable in polymers as are the structurally similar acrylic esters. Specially formulated for excellent abrasion resistance.

309 gelcoat plus 33 95 315 00. It s great having someone so knowledgeable just one phone call email or im away. Vinyl esters are more tolerant of stretching than polyesters. Vinyl esters have enhanced mechanical properties compared to polyesters with physical strength better impact and thermal shock resistance.

While vinyl ester resins are classified as polyester based formulations they are actually an intermediate between a polyester backbone and epoxy terminations on the ends of the molecules. Plasite 4110 meets the fda requirements for 21 cfr 175 300 and 177 2420 and is suitable for potable water service per nsf std. Open molding hand lay up spray up smc bmc rtm. Duratec vinyl ester primer 1799 006 grey 1702 006 black and white duratec high goss topcoat black clear orange duratec mold repair putty black clear orange duratec ve fairing primer 1799 052.

Vinyl esters undergo homopolymerization via a radical mechanism. 304 orange tooling gelcoat 29 90 299 90. High density cross linked products are suitable for temperatures above 250 o f 121 o c. Vinyl alcohol containing polymers are prepared by hydrolysis of the corresponding vinyl acetate polymers.

940 vinylester fairing compound 19 00 216 50. The vinyl groups refer to these ester substituents which are prone to polymerize. Vinyl esters the majority of polymers in this category consist of vinyl acetate and its copolymers. Vinyl ester resins offer increased strength corrosion resistance and durability and are used in a wide variety of applications.

Hdt of 280 f 138 c. Vinyl ester has fewer open sites in its molecular chain. Standard epoxy vinyl ester resins are limited to 220 250 o f 104 121 o c in most applications. This makes it much more resistant to water penetration hydrolysis which can cause osmotic blistering.

Molding conditions for vinyl esters are similar to those for polyesters. The most widely used member of the category is vinyl acetate. Poly vinyl acetate is unique in that the most common polymerization method results in a nonlinear highly branched polymer. Vinyl esters are stronger than polyesters and more resilient than epoxies.
