Product Description

Product Description

Brief introduction:INV-V650 is a low-viscosity halogen-free flame-retardant vinyl ester resin, which maintains a low mixed viscosity under the premise of excellent flame-retardant performance. It is suitable for RTM and vacuum infusion process to manufacture epoxy-based flame-retardant composite materials.

Epoxy vinyl ester resin is prepared by the chemical reaction of epoxy resin and methacrylic acid through ring-opening addition. It retains the basic segment of epoxy resin, and has the good process performance of unsaturated polyester resin. After curing under suitable conditions, it shows some special excellent properties.

Matters needing attention:1. The transportation shall comply with the regulations on the transportation and handling of hazardous chemicals in Chapter V of the State Council's "Regulations on the Safety Management of Chemical Hazardous Substances".2. The product should be stored in a cool place below 25ºC, avoid fire and isolate the heat source.3. The shelf life is 3 months under the specified storage conditions.

Features:The standard bisphenol A epoxy vinyl resin is a vinyl resin synthesized by the reaction of methacrylic acid and bisphenol A epoxy resin. It has been dissolved in styrene solution. The specific molecular structure is shown in the figure below.

Product Parameters

Liquid resin properties (25ºC):

Project	INV-V650
Appearance (visual inspection)	white cloudy liquid
Viscosity (mPa.s)	200-300
Density (g/cm3, 25ºC)	1.1-1.2
Storage temperature (ºC)	normal temperature

Usage:

Suggested recipe	Name		Weight ratio
	INV-V650		100
	Hardener AKZO M-50		1-2
	Accelerator AKZO NL 49P(1% Co)		0.5-2
	The recommended weighing tool is accurate to 0.5% to ensure the accuracy of the ratio; first add the accelerator and stir it evenly, then add the curing agent and stir it evenly before use, and cannot be added at the same time.
	If too much resin is mixed at one time, the pot life of the product will be shortened;
Gel time	Temperature (ºC)	Gel time (min)
	25	30-60
	The gel time can be adjusted by the amount of accelerator added, and the product can be adjusted according to customer needs after it exceeds the range.

Composite properties:
