DESCRIPTION:
Metoset is a rapid curing 'one shot' two part chemical anchoring cartridge system based on a polyester resin. Applied in one single action to produce a cost effective, tough, chemical resistant fixing. Metoset is ideal for close-to-edge applications (unlike expansion anchors) as no stress is placed on the surrounding substrate. Versatile in use Metoset is suitable for fixing wall ties, starter bars, studs, bolts or larger screws in a wide range of substrates including brickwork, concrete, masonry, stone and PFA blocks. Hollow base materials can be securely fastened into by using metoset in conjunction with a sleeve or sieve.
PREPARATION:
| 1. Drill hole to the correct diameter and depth (see chart for guide), ideally using a rotary percussion machine. For optimum results the hole must be coarse sided. If the holes are produced by diamond drilling the surfaces should be thoroughly roughened. |
| 2. Remove all dust and debris from the hole using a hand air pump or a stiff rotary brush. |
| 3. All bars should be clean and free from oil or grease and all flaking rust should be removed. Threaded rod or studs should be chisel-ended to prevent them from being unscrewed from the cured resin. |
APPLICATION:
| 1. Attach the mixing nozzle to the cartridge (screw down hand tight). |
| 2. Place cartridge into Metoset dispensing gun. |
| 3. Open the cartridge by pressing the green end of the colour coded valve. Gradually pressurise the cartridge by activating the hand trigger a few times until material passes through the mixing nozzle. Stop pressurising and allow the material to flow until an even colour is obtained (approximately 5 - 6 inches of extruded material should be adequate). |
| 4. Press the red end to close the valve. Insert the nozzle into the base of the hole. Open valve again by pressing the green end and activate the trigger, withdraw the nozzle slowly as the hole fills. |
|
5. Once the required fill is achieved shut of the valve and wipe off excess material. Insert the fixing with a rotating action to the desired depth. Once all application have been carried out, release the pressure by pressing the slide release arm on the back of the trigger stop and pulling back the slide rail. Remove the used mixing nozzle and wipe away excess material on the end of the cartridge.
|
N.B. Once material has started to extrude through the nozzle over pressurising the system will not increase flow rate, and can cause leakage from the rear of the cartridge.
TECHNICAL DATA:
Mixing ratio - 10 : 1 by volume as supplied in 380 ml cartridge.

Tension figures quoted are tested in accordance with BS 5080 part 1 in 63 N/mm2 concrete blocks (12x12x12 inches). In all cases for 16mm and 20mm anchors failure of the concrete block was observed before the anchor was dislodged.
The ultimate pull out strength is varied by:
| 1. |
The strength of both the substrate and bar/stud. |
| 2. |
The length of the resin bond to bar. |
| 3. |
Hole preparation. |
| 4. |
Anchor separation. |
Safety factors of between 2:1 and 4:1 should be considered depending on the strength and nature of the substrate. Due to the inconsistent nature of hollow blocks and bricks tension figures may vary. Site testing should be carried out where necessary to establish particular suitability. In order to achieve maximum performance the distance between the centres of the anchors should be a minimum of 2.5 x the embedment depth, and 1.25 x the embedment depth for the minimum distance from the edges.
STORAGE:
Store in a dry area between 5 dg C and 25 dg C. Do not expose to direct sunlight. Storage at higher temperatures will reduce the shelf life
HEALTH AND SAFETY DATA:
Metoset contains styrene and is flammable. Do not smoke and do not allow naked flames to come into contact with this material. Avoid breathing vapour and wear suitable protective clothing such as gloves and overalls. On contact with skin wash off immediately with plenty of soap and water. For further information refer to the material safety data sheet
