Product details
Â
Resin Capsules are a two compartment capsule with the outer sheath made from polyester film. The one compartment contains the resin mastic and the other compartment contains the catalyst paste.
The insertion and rotation of a roof bolt breaks the sheath and allows the resin and catalyst to be mixed. This thixotropic compound sets after a specified setting time and creates a chemical bond between the anchor and the strata.
Â
Â
High load transmission due to high bonding strength
Short setting times allow fast bearing support of the rock-bolt and overhead roof bolting
Ease and speed of installation
Simple and safe handling

A special plastic cap with radial projected ends (known as a "parachute") may be fitted to one of the cartridge tips and acts as a retaining element preventing the cartridge from sliding out of the bore -hole. The choice of cartridges depends on the diameter of the rock bolt and bore -hole. An annular gap of 3 mm is ideal to permit rupture of the cartridge membrane and to ensure adequate mixing of the two components.
After drilling, the desired number of cartridges are inserted into the bore -hole followed by the rock-bolt. The end of the rock-bolt is angle cut so as to form a sharp tip to ease membrane rupture. As soon as the rock -bolt is inserted into the bore-hole it is spun in order to facilitate the mixing of the resin with the hardener. Spinning is stopped as soon as the rock -bolt is inserted to full length of the bore-hole and as per the recommended “Spin Timeâ€. The Rock-bolt is then left immobile (as per the recommended “Hold Timeâ€) in order to allow the hardening reaction t o take place.
The hardening time (hold time) depends on the resin set time, the rock temperature as well as to the energy given to the system while the rock-bolt is inserted into the bore-hole.
Â
Â
Â
The required diameter and length of cartridges is calculated by estimating the volume of the annulus between the bolt and the borehole. Cartridges are manufactured in diameters of 21, 23, 25, 28, 32 and 35 mm and standard lengths of 380, 400, 450, 500, 600, 900, 1000, 1100 and 1350 mm. Other lengths and diameters of the cartridge can be manufactured upon request.
