Physico-mechanical characterisation of finishing product systems (paint, varnish, etc.), adhesives, flexible sealing sheets

Tests to characterise the physical and mechanical properties of finishing systems applied to joinery, floor coverings, adhesives and flexible waterproofing sheets, enabling their performance to be assessed and compliance with current classification standards and requirements to be established.

• Characteristics concerned :
  Artificial ageing, natural ageing, water permeability, water vapour transmission, thermal conductivity and resistance, shear and tensile strength and deformation, water penetration resistance; resistance to climatic and cyclic stresses, Persoz hardness, gloss measurement, colour measurement, abrasion resistance, light resistance, adhesion resistance, chemical resistance, impact resistance, scratch resistance
• Testing capabilities :
  Ageing chambers (QUV), accelerated degradation wheel (RDA), natural ageing field, climatic chambers, perspirometer (Gravitest), flux meter, lambdameter, abrasion tester, impact test bench, scratch test bench, Persoz pendulum, gloss meter, spectrocolorimeter, etc.
