The following mixtures need to be prepared
Mixture 1: ACRYL-R Resin (A1) + ACRYL-R catalyst (A2)
Mixture 2: ACRYL-R Initiator (B1) + water (alternatively
ACRYL-R Polymer (B2))
The mixtures are then mixed in ratio of 1:1 Prepare the
mixture of components A1 and A2 and B1 + water in two
opaque plastic containers each with a lid. Take an equal
volume of each component and check the setting time of
the mixture. Adjust the ratio if necessary. The mixture of
component A1 and A2 is stable for at least a few hours, if
kept covered in a cool and dry place even longer. The
mixture of component B1 + water is stable for a few days
below a temperature of 25°C.

Application For slow setting one can use a mono-
component pump. Only prepare amounts that can be

injected before the gel sets by mixing one volume of
components A1 and A2 and one volume of components

B1 and water. For all types of setting, the use of a two-
component methacrylate pump is recommended. Both

the mixtures are injected in a volume ratio of 1:1.
Handling When handling the ACRYL-R system, observe the
recommendation set out in the MSDS sheets. Only
stainless steel or plastic containers can be used (PVC,
polyethylene, polypropylene). Avoid any contact between
the A2 component or catalyst and the B1 component or
initiator without having been diluted in their respective
mixture (resin + cat and initiator + water). The mixtures
have to be perfectly homogeneous before use. Do not add
more than three volumes of water. Cleaning of

• Composition The standard injection fluid is obtained by mixing two mixtures in a ratio of 1:1. However depending on the conditions of the injected substrate the quantity of water present in the injection solution may be up to 3 time the volume of resin.
• Viscosity The viscosity of the ACRYL-R solution will depend on the temperature and dilution. It will remain constant up to the setting point.
• Setting point Gelling slows down at low temperature but still fast even below 0°C. In acid conditions the reaction is slowed down, while under alkaline conditions the reaction is speeded up. The presence of minerals and metals (especially iron and copper) may increase or decrease the rate of setting, depending on their concentration. When immersed in water the unconfined gel can absorb up to 2 times its own weight of water in a few weeks without cracking. Under humid conditions the volume of the gel will remain approximately constant. In the absence of water, the gel will slowly shrink, without cracking. These dimensional changes are reversible and do not degrade the gel. For better control of dry-wet cycles use ACRYL-R Polymer

Store at a temperature above 0°C and below 25°C. Do not
expose directly to light or sunlight. Storage in these
conditions for min. 12 months

❖ Do not breathe dust/fume/gas/mist/vapor/spray
❖ In case of improper ventilation wear respiratory protection
❖ Wear protective gloves/clothing and eye & face protection
❖ If in eyes: Rinse cautiously with water for several
minutes, remove contact lenses, if present & easy to do.
Continue rinse.
❖ If on skin or Hair: - Take off immediately all
contaminated clothing. Rinse skin with water & shower

The Avinject Acryl-R system consists of three products:

• Component A1: Acryl-R resin.
• Component A2: Acryl-R catalyst, a liquid activator for standard setting times between 10 seconds and 30 minutes.
• Component B1: Acryl-R initiator, in powder form to be dissolved in water.
