Description

ADESIVER 327 PU is a two-component polyurethane adhesive without any epoxy modification with very low emission of volatile compounds: CERTIFIED EC1R Plus. ADESIVER 327 PU has been formulated to answer the needs of those workers that do not want to renounce to the typical characteristics of adhesives with 100% of non-volatile matters, but they are allergic to epoxy adhesives.

ADESIVER 327 PU can contribute to the achievement of QI CREDIT 4.1 according to the parameters of the GEV dated 03 March 2009, because it meets the certification LEED protocol (Leadership in Energy and Environmental Design).

  • mixture ratio: 10:1;
  • application temperature: +10°C ÷ +25°C;
  • application: notched trowel n. 5;
  • pot-Life: 1h  (at 20°C and 65% R.H.);
  • hardening: 36-48 h (at 20°C and 65% R.H.);
  • coverage: 1200-1800 g/m² depending on the subfloor;
  • colour: oak, walnut;
  • thinning (if necessary): DILUENTE DMC 50;
  • storage stability: 1 year (in original sealed containers at temperatures between +10°C and +25°C);
  • packaging: 11 kg (10+1);

Laying conditions

Subfloor

dry, clean, no-dust creating, not too rough.

Humidity of subfloor

2,0% max with cement subfloors

1,7% max with radiant heating subfloors

0,5% max with anhydrite subfloors

0,2% max with radiant heating anhydrite subfloors

Other uses:

  • adhering of heat and sound insulating panels (cork, expanded polyurethane, rock-wool);

  • adhering of tiles on asbestos cement and chipboards;

  • adhering of wood and building materials (ceramics, stoneware-marble tiles) on to metal bases.

How to use

Do not dilute ADESIVER 327 PU with alcool. After mixing the two-components, spread ADESIVER 327 PU with a notched trowel uniformly on a clean subfloor, working the adhesive to incorporate any residual dust. Proceed with the laying ensuring that the wood elements are put together properly and gently hammered in order to ensure full contact with the adhesive. Perfect adhesion to the subfloor is ensured if at least 65% of each wooden component is in direct contact with the adhesive. In presence of dust-creating and porous subfloors, we recommend to apply first one coat of PRYMER A, PRYMER PUB 77 or PRYMER SF 1105 (see technical data sheets). After 24 hours, proceed with the application of the adhesive. In presence of humid subfloors, we recommend to apply first one coat of PRYMER PUB 77, PRYMER SF 1105, PRYMER EPOX WETT, PRYMER WB 328 S, PRYMER 100 or PRYMER FAST 500 (see technical data sheets). If the wooden floor has to be laid on glassy surfaces (ceramic tiles, enamelled tiles, polished marble, etc.), remove and clean the surface from dust, grit, glue and waxes. Apply by cloth the adhesion promoter DILUENTE APA following the correct application time (see technical data sheet), than apply ADESIVER 327 PU . The subsequent sanding can be operated after 3-4 days according to the atmospheric and the wooden floor's hygrometric conditions. We do not recommend to dip the heads of the tiles into the ADESIVER 327 PU while laying them. If necessary, dip the heads of the wood into a dispersion adhesive as PARKETTKOLL products (see technical data sheets) which has a very strong wood to wood adhesion avoiding also the typical "slipping" of the elements. The subsequent sanding can be operated after 3-4 days according to the environment weather and room conditions. When laying down pre-lacquered wooden floor, if a wood piece gets accidentally dirty with glue, clean immediately with DILUENTE PULIPAR or DILUENTE PULIPAR W (see technical data sheets). We recommend, while using ADESIVER 327 PU, to use all the personal prevention systems.
