301 Epoxy resin & hardener (kit)
This product can be applied to manually prepared surfaces to create a GRP layer around the entire circumference of leaking pipe surfaces. Thanks to the incorporation of layers of high-strength woven fiberglass, the pipe repair system has proven to offer over 10 years’ protection to damaged, leaking or porous pipes.
In general, the composite wrapping system can be applied to pipe diameters ranging from 1 to 50 inches and, once cured, can withstand temperatures of 150°C and pressures of 300 psi.
Indications :
-
- Porous and leaky pipe surfaces
-
- Encapsulation of long lengths of large-diameter piping
-
- Sealing leaking tank joints
-
- Sealing leaking flange connections
Surface preparation
Injection application – Bonding dissimilar materials – Encapsulation using technical fabrics
1. Wherever possible, all surfaces should be abrasive blasted in accordance with ISO 8501/4 SA2.5 (SSPC SP10/NACE 2) and with a minimum blasting profile of 75 microns using an angular abrasive.
2. However, this product tolerates less ideal surface preparation and will adhere to surfaces prepared using hand tools, mechanical tools and hydro-rubbing.
3. Corrosion pits should be rebuilt using Resimac 302 epoxy repair cement, which can also be used to improve adhesion on poorly prepared surfaces.
*Please note that for best results, the preparation surface must be cleaned by sandblasting. Using inferior repair techniques may affect product performance.
Mix
Before mixing, please check the following points:
1. The base component is at a temperature of 15-25°C.
2. Ambient and surface temperature above 5°C.
Once these 2 checks have been carried out, mix the product.
1. Transfer the contents of the Activator unit to the Base container.
2. Using the spatula provided (300-450gm units) or an electric mixer (6kg units), mix the 2 components until a uniform, streak-free material is obtained.
3. As soon as mixing begins, all the material must be used within 25 minutes at 20°C.
Application
Injection applications :
Dispense the product into a single-component cartridge to a volume of 1ltr (0.25 US gallon). Using a
single-component, air-fed injection pump, material can be injected into gaps to bond dissimilar materials.
Bonding dissimilar materials :
The mixed product can be used to bond a wide range of materials, including concrete, plastic and metal.
Apply the product with a brush or application tool to a wet film thickness of between 1 and 4 mm (40mil – 3/16″).
Encapsulation with technical fabrics :
The mixed product can be used with glass tape, glass cloth, short-fibre matting and linen cloth.
Curing time
At 20°C, applied materials must be allowed to cure for the times indicated below before being subjected to the conditions indicated. These times will be extended at lower temperatures and reduced at higher temperatures:
Operating time – 25 minutes
Touch-dry – 2 hours
Dry hard – 24 hours
Full cure – 3 days
Color
Mixed material – Opaque
Base component – White gel
Activator component – Light yellow gel
Coating time
Minimum – the applied material can be covered as soon as it is dry to the touch.
Maximum – covering time must not exceed 8 hours.
Once the maximum recovery time has been exceeded, allow the material to harden before abrading or sanding to remove surface contamination.
Shelf life
5 years if unopened and stored under normal dry conditions (15-30°C).
