epoxy vinyl ester resin for vaccum infusion process

Atlac®430LVGT250 vinyl Resin properties introduction

Atlac®430 LV GT 250 is a pre-accelerated Epoxy bisphenol A vinyl resin styrene olefin solution with moderate reactivity and low viscosity. Atlac®430 LV series has multiple gel time versions, such as Atlac®430 LV GT 50 and Atlac®430 LV GT 150. The resin is suitable for all manufacturing methods, especially for winding, centrifugal casting, hand paste molding and jet molding processes.

Atlac®430LVGT250 vinyl resin has excellent acid and alkali resistance, heat resistance, bleaching and excellent mechanical properties so the process has good wettability and fluidity during operation. Atlac®430 LV GT 250 can be used in Fiberglass vvreinforced components with excellent chemical resistance for better mechanical properties and good compatibility with carbon fiber and arylon. It can also be used for corrosion resistance engineering of ships, auto parts, containers, storage tanks, water conservancy engineering, sewer pipe repair and so on. Atlac®430 LV GT 250 vinyl resin with extremely low viscosity, suitable for vacuum leadin, RTM and other processes; It has been certified by China Classification Society CCS and LR by Lloyd's Register of Shipping.

Atlac®430LVGT250 vinyl resin curing conditions and processes

Add 1gButanox LPT and 0.58NL49P to 100g resin and cure at room temperature for 24 hours and at 80℃ for 24 hours. Four layers of 450g/m2 Glass Fiber staple felt.

Atlac®430 LV GT 250 vinyl resin is generally a non-sticky cured surface. To ensure that the surface in contact with air is non-sticky, appropriate additives (such as wax solution) can be added to the resin. The final cured state can be cured at a high temperature for several hours (80-100°C) to achieve the best physical and chemical properties. But it is especially important for curing after use in parts that are resistant to chemical corrosion. Low hydrogen Peroxide, or cyclohexanone peroxide, or cobalt solution curing systems are recommended. A well-cured final product will not have sticky surfaces

Atlac®430LVGT250 vinyl resin for use and storage paramete

Resin operations are performed under the right conditions, usually with MEKP/Co curing at temperatures above 15 ° C.

Before use, it should be noted that the resin should be stored in the original packaging in the drying room of 5-30°C, to avoid opening the barrel and the barrel damage situation. Temperature and light exposure will reduce the storage life of styrene containing resins, so it should be stored away from direct sunlight and heat sources, stored in dark and 100% light sealed containers.
