Gel Time (mins)
Heat resistance HM type resin, high strength and rigidity, suitable for medium heat resisting required product.
medium heat resisting required product.
Vinyl ester resin and unsaturated polyester resin, curing at room temperature, the surface of the product has a sticky phenomenon, which brings inconvenience to the application.The main reason is that oxygen in the air participates in the polymerization of vinyl ester resin surfaces.To overcome this shortcoming, researchers have developed many effective methods.One of them is to synthesize air dry vinyl ester resin by inserting alkyl ether (CH2=CH - CH2 - O -) groups into the structure of vinyl ester resin.This kind of resin is suitable for the production of high-grade gas drying gel coat, coating, sealing fabric.
It is worth noting that the content of allyl ether in the resin has a suitable value, too small resin can not absorb oxygen well, too large due to the "automatic polymerization", the air drying will also decline.
