VINAVIL 2256 L is successfully used as a mono-component adhesive when water resistance to EN 204 D4 classification is required. Tests for the evaluation of these properties are carried out on samples made as follows:
- application of adhesive: both sides at the rate of approx. 150 g/m2,
- pressing condition: 0.5-1.0 N/mm2,
- pressing time: 1-2 hours.
The joints obtained by using VINAVIL 2256 L show an excellent resistance to static loads. Moreover, the good penetration of the dispersion into substrates and the excellent cohesive strength of the adhesive enables the making of bonded joints
that, under shear stress in compression, show a breaking of the wood itself or a high percentage of wood fibre tear.
