Anchor bolt adhesives
POLYURETHANE ADHESIVE – PROMOPUR
The PROMOPUR two-component polyurethane adhesive has been designed to be used in methane and non-methane underground mines, in areas with an “a”, “b”, “c” degree of methane explosion hazard and A and B levels of coal dust explosion hazard. It is designed for consolidation, sealing, and strengthening of cracked rock mass in areas with dry, loose rocks and coal deposits, also for injectable anchor bolts. It can be injected into cracks and pores in rocks and coal deposits. It can also be used for sealing and bonding structures. The adhesive is made by mixing components A and B in a ratio of 1:1 by volume. SIL-PUR 80 is a flame-retardant and self-extinguishing adhesive.

ORGANOSILICON ADHESIVES – SIL-PUR 80
The two-component organic-mineral adhesive SIL-PUR 80 is intended for use in methane and non-methane underground mines, in areas with an “a”, “b”, and “c” degree of methane explosion hazard and A and B levels of coal dust explosion hazard. It is designed to be used by injection for sealing, strengthening, and consolidation of cracked rock mass in areas with dry as well as humid and damp loose rock and coal deposits. It can also be used for sealing and bonding structures and fixing steel, string, and wire anchors made of smooth and corrugated steel. The adhesive is made by mixing components together in a ratio of 1:1 by volume. SIL-PUR 80 is a flame-retardant and self-extinguishing adhesive.

ADHESIVE CARTRIDGES
Adhesive cartridges are designed for installing steel, string, and rope anchors in rock mass. They can also be used in tunnel construction. The task of roof supports in excavations is to maintain the stability of the roof and timbering in these excavations.
The adhesive has a greater strength than a steel anchor. Adhesive cartridges bind the anchor with the rock mass in extremely difficult technological conditions. The structure of the cartridge means that it can be easily and safely placed in a hole. And the glass vial with a curing agent ensures its even distribution throughout the entire volume of the cartridge.
