Sewer repair
CarboLith HL

Minova CarboTech GmbH
Am Technologiepark 1

CarboLith HL is a non-foaming, elasticised two-component resin having good adhesion,

for impregnating inliners during sewer rehabilitation work, in particular of service lines.

CarboLith HL

o impregnates polyester mats well
o cures excellently in thin layers, without heating or UV radiators
o has high resistance to aggressive water, acids and alkaline solutions
o CarboLith HL does not saponify

Material Data

Component A
Component B
Composition and Properties
Components: CarboLith HL, component A, is a special sodium silicate with additives. Component B is a modified The curing from component A results in a silicate; simultaneously a solid polyisocyanurate/polyurea is formed from the component B. Final Product: Together they form an interpenetrating network, a tough-elastic, non-foamed silicate resin (or-
ganomineral resin).


The desired resin quantity is homogeneously mixed from the two components in the volume ratio
1 : 2 in a mixing container using a drill mixer. For this, it has to be observed that only that quantity of resin is mixed which can be used up within a short period of time. The larger the formulation, the faster the resin cures due to the resulting reaction heat. After the mixing, the resin is poured into the readily cut hose or it is intermingled under vacuum using a roll or an impregnation device. The liner impregnated in this way is then inserted into the sewer by means of the inversion or re-traction method using compressed air or water where it cures. The reaction process can be checked
Hazard notes and safety advice for handling CarboLith HL
Observe the usual precautionary measures for handling chemicals. Symbol: Xi (irritating) R36/38 Irritating to eyes and skin. S26 In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. S36/37/39 Wear suitable protective clothing, gloves and eye/face protection. S60 This material and/or its container must be disposed of as hazardous waste. (s. "Disposal") Component B R20 Harmful by inhalation. R36/37/38 Irritating to eyes, respiratory system and skin. R42/43 May cause sensitisation by inhalation or skin contact. S23 Do not breathe spray. S26 In case of contact with eyes, rinse with plenty of water and seek medical advice. S28 After contact with skin, wash immediately with plenty of water. S36/37/39 Wear suitable protective clothing, gloves and eye/face protection. S38 Wear a respirator if ventilation is inadequate. S45 In case of accident or if you feel unwell, seek medical advice immediately. S60 This material and/or its container must be disposed of as hazardous waste. (s. "Disposal") When at work, appropriate personal protective clothes, protective gloves and goggles / faceguards must be worn. Persons who frequently or regularly handle CarboLith HL or other polyurethane res- ins have to subject themselves to the prophylactic medical examination of the trade associations
according to G27. Further details can be found in the safety data sheet.
Storage, shelf life: At least six months after delivery or twelve months after production, for dry
storage between 10 and 30 °C. Frost can damage the A component. (Flaking; contact Minova Car-boTech GmbH). When this time is exceeded, we recommend having the material checked by Mi- nova CarboTech for compliance with specification. The local legislation on storage has to be observed. (s. safety data sheet)


In Germany completely emptied cans are taken back free of charge by the points of acceptance of the KBS system (recirculation system for steel sheet packing materi- als, further details of addresses available from Minova CarboTech). Empty cans should be cleared of liquid by punching a hole through the edge of the cover using a sharp object (e.g. screwdriver). Turn them upside down, until no liquid flows out any longer. We recommend to have any liquid residuals cured. The cured resin can be disposed of in a similar way as domestic waste (disposal code no. 20 01 39).
