Technical Details & Test Data
- Processing
Mix ratio by weight: 2.44: 1 (RX: HX)
Mix ratio by volume: 2: 1 (RX: HX)
This product requires the AX590EF/NC blowing agent to produce a foam, increased loading will increase the blow ratio. Recommended loading of 0.5 to 3.0 parts by weight (pbw) AX590EF/NC per 100 parts RX590EF-1/NC is recommended. The blow ratio is not linear with increased loading of blowing agent, and therefore levels off at higher loadings.
Typical Blow ratio with AX590EF/NC loadings per 100 parts RX590EF-1/NC:
- 0.5 pbw = 1: 1.7 Density = 0.65 g/cm³
- 1.0 pbw = 1: 2.2 Density = 0.5 g/cm³
- 2.0 pbw = 1: 2.7 Density = 0.4 g/cm³
- 3.0 pbw = 1: 3.1 Density = 0.35 g/cm³
Cure Schedule (150ml) Room Temp Standard Cream Time (minutes) 1 - 2 Gel Time (minutes) 240 RTM015 Light Handling (hours) 12 - Full Cure (hours) 24 - *RT is defined as 20-25°C
The above are typical values and will vary depending on the cured mass and application. Hotter temperatures may be used for faster cure but
will result in higher post cure shrinkage and higher cure exotherm. Experimentation and testing is suggested to avoid side effects.
Packaging & Availability
- Packaging
- PX590EF-1 is available in Bulk, Twinpacks
- AX590EF/NC is available in Bulk
- Twinpacks - Part Numbers
PX590EF-1/NC/300
Twinpacks are pre-weighed resin and hardener components contained in a tough flexible film, separated by a removable clip and rail. Once the clip and rail has been removed the resin and hardener is thoroughly mixed within the bag and is immediately ready for use. Mixing will normally take ~ 2 minutes due to the viscosity; but pay special attention to the corners. Twinpacks are ideal for small to medium production runs, prototyping and on-site or field use. The twinpack weight/volume may also be tailored to a specific size.
- Bulk Materials - Part Numbers
AX590EF/NC/200
Both resin and hardener are supplied in 5kg, 25kg and 200ltr drums and fully evacuated and ready for use. Care should be taken to ensure when mixing the resins air is not entrained in the mixture. If this is unavoidable the mixed resin and hardener should be re-evacuated before dispensing. The bulk resin and hardener materials can be dispensed from suitable dispensing machinery. Fluid Research produce a range of suitable dispensing machines.
- Kits and Sets - Part Numbers
- Kits and Sets are provided in separate containers to the correct ratio.
- In Kit form, pour contents of the smaller container into the larger container and use it as a mixing vessel.
- Stir well using an appropriate mixer until homogeneous.
Note: Incomplete mixing will be characterized by erratic or partially incomplete cure even after extended time periods.
Storage & Handling
- Cleaning
All equipment contaminated with mixed material should be cleaned before the material has hardened. TS130 is a suitable nonflammable cleaning agent, although other solvents may be found suitable. TS130 will also remove cured material provided it can soak for several hours.
- Storage and Shelf Life
12 months at 25°C Bulk packaging.
Many epoxy resin systems are prone to crystallization as epoxy resin is a super-cooled fluid. This condition may give the product a gritty or grainy appearance (or hazy in clear products). Products in this state will not usually cure to normal and expected properties. In extreme cases it may appear solid and cured. Fluctuating temperatures (within 5 to 50°C) aggravate this phenomenon. Heating the individual component to 50 to 60°C while stirring can usually restore products to original state. Storage at 25 +/- 10°C is optimum for most products
Some epoxy systems are prone to settling due to high filler content and should be inverted every two to three weeks to reduce the accumulation of the fillers on the bottom of the containers.
Inventory should be rotated on a FIFO (first in, first out) basis.
