PAVIWATER® T68 A+B
Waterborne transparent epoxy product
Waterborne 2 component epoxy product, based on amine and epoxy resins. The product has a high solids content: the viscosity can be lowered by diluting with water. The film has good mechanical properties and good resistance to solvents.
Type: Funds, Consolidants, Primers
Description
Water base two-component epoxy system, based on epoxy and amine resins. The product has high solids content: the viscosity can be significantly lowered by diluting with water. The film obtained has good mechanical characteristics and good resistance to solvents.
Use
Primer for resinous coatings. Consolidating for crumbly cementitious surfaces. Anti-dust impregnating for cementitious surfaces. Primer for polyurea-based waterproofing systems on bitumenpolymer and asphalt substrates. Realisation of fiber glass reinforced coatings.
Support
The substrate must have a minimum compressive strength of 25 N/mm2 and a tensile strength of 1.5 N/mm2.
Preparation of the support
If the concrete is new, wait for complete curing. The surface must be solid, absorbent and free from the presence of oils, surfactants, water, dust. Any detachable parts must be removed. The floors must be treated mechanically, by sanding. Any holes can be repaired with PAVIRAPID or SIVITCOL.
Application
At the time of application, combine the two components in a single container and mix carefully for 2 minutes, using suitable equipment (drill with propeller). Slowly add the dilution water while stirring, stir the product for 1 minute and use within the time of use.
PAVIWATER T68 can find its application as:
Impregnating and consolidating primer for cementitious surfaces: apply two coats for a product consumption of approximately 50 g / m2 (for each coat):
- 1st shot - one part (A + B) + 3 parts of water
- 2nd shot - one part (A + B) + 1.5 parts of water
Binder for making fiberglass coatings (with MAT 225): one part of product (A + B) + 0.2 parts of water, for a product consumption of 0.70 kg / m2; the cycle must subsequently be completed, to create floors.
Primers for polyurea-based waterproofing systems on bitumen-polymer or asphalt substrates: apply one part of the product (A + B) + 0.5 parts of water, for a indicative consumption of the product between 0.10 and 0.20 kg/m2 depending on the characteristics of the substrate. On the still fresh primer, sow QUARZO B1 up to the point with a consumption of 1-2 kg/m2 the next day to eliminate any excess unbound quartz
Warnings
Do not apply on gypsum-based plasters intended for humid environments (e.g. showers).
Product for professional use, the buyer undertakes to follow the above warnings in the application of the purchased product and the instructions in the safety data sheet.
