Minova Resins

Minova have manufactured Lokset resin capsules since the late 1960’s and are the leading supplier and innovator in this field. Australian development and manufacture ensure security of supply, service and support.

The Lokset system consists of an easily handled capsule, containing a highly reinforced polyester resin component, together with its catalyst, in accurately measured quantities. The rotation of the bolt during installation ruptures the capsule, shreds the skin and mixes the two components causing a chemical reaction and transforming the resin mastic into a solid anchor.

The Lokset resin capsule series is available in multiple configurations of single/double length combinations, diameter, set time, set time combinations, viscosity and shelf life.

• Easy to install, requiring no specialty injection equipment
• Resistant to anchoring failure caused by blasting or vibration
• Rapid anchoring of the bolt to the surrounding strata
• High load transfers achievable almost immediately
• Full column bonded bolts strongly resist the horizontal and lateral strata movement associated with convergence
• Provides strength and rigidity to prevent sag
• Acts as a reinforcement that clamps the individual strata layers into a single high strength beam
• Effectively seals wet, dripping holes and in most cases eliminates deterioration of the hole and surrounding strata
• Unaffected by sea or fresh water, mild acids or mild alkaline solutions
• Immediately fixes rock bolts / anchors
• Protects bolts from corrosion, can be used in wet/underwater condition

• two speed capsule that eliminates the need to use multiple, single speed resin capsules
• Reduced handling and wastage
• Guarantees both fast and slow set capsules are installed
• Both speeds compatible giving reduced back pressure and easier penetration
• No plastic or cardboard joiners required
• Allows roof bolt to be pre-tensioned quickly

• The Supamix capsule’s low mastic to catalyst ratio improves mixing consistency and installed bolt quality
• Improved formulation providing 6 months shelf life at 25° C to reduce wastage
• Lower viscosity and modified rheology resulting in easier push through and improved encapsulation.

Specially formulated resin mastics to aid insertion where long tendon support is required. This range was developed for use with all resin anchored cable bolts and includes F-Series and J-Series capsules. J-Series capsules are used as an anchoring support in strata where larger annular gaps between bolt and hole diameters are encountered with long tendon strand cables.

Can be used with a range of long tendon support cables and include; SuperStrand cables, Flexibolts, Spinbolts, Megabolts, and Cable bolts.

• Aids mixing in larger annular gaps due to a specially formulated resin mastic and catalyst
• Rapid strength build up, bolt will take load almost immediately
• Eliminates the need for costly and time consuming post grouting by completing full bolt encapsulation in single operation

Two resin capsules joined and folded in half for packaging. A system developed to enable full encapsulated mechanised resin bolting, utilising the Quick‑Chem™ resin capsule insertion system. Lokset X2 range is available with any single or combination of Minova resin capsule mastics. Any capsule combination can be ordered and the individual Quick-Chem caps are supplied in the boxes.

https://www.minovaglobal.com/apac/products/lokset-resin-capsules/quick-chem-system/

Patented insertion system developed to remotely install Lokset resin capsules into boreholes for rock bolting. The Quick-Chem system is used in conjunction with Lokset resin capsules to ensure quick, safe, efficient and remote insertion of the resin capsule into the bolt hole.

The system aids mechanical installation of resin capsules where hand installation is not practical. The system includes a purpose designed retaining cap (attached to the resin capsule) and an insertion tube. The insertion tubes consist of a 25mm, 26mm, 30mm or 36mm diameter tube and R32 threaded adaptor sleeve. The tubes are fitted into the Jumbo drifter, and used to safely insert resin capsules undamaged to the back of each borehole.

Quick-Chem consists of a retaining cap (attached to the resin capsule) and an insertion tube. The tubes are fitted into the Jumbo drifter, and used to safely insert resin capsules undamaged to the back of each borehole.

Quick-chem Features:

• Safe, enables resin capsule to be inserted in bolt hole from remote location under supported ground
• Quick, no requirement for lifting baskets or manual resin insertion, capsule can often be placed in insertion tube from operator’s cab
• Efficient, up to 200-hole insertions can be achieved from each tube
• Easy to use, clear tubing indicates position of resin capsule
• Robust; strong and flexible insertion tube
• Versatile, can be used with most drill rigs such as Robolters, Jumbo’s, Boltec etc and in most rock bolting situations
• Adaptable, can be inserted through mesh and broken ground
• Reliable, assists the resin capsule in reaching the back of the hole undamaged
• Available in various lengths and diameters
