TECHNICAL DATA SHEET VINAVIL PROVISIONAL …

1 VINAVIL 2256 L02WD0009 - 03/14P 1 - 2 VINAVIL TECHNICAL data SHEETPROVISIONAL data SHEETVINAVIL 2256 L is successfully used as a mono-component adhesive when water resistance, to EN 204 D4 classification is for the evaluation of this properties are carried out on specimens made as follows:Application of adhesive: both sides at the rate of approx. 150 gr/m Pressing condition : N/mm Pressing time : 1-2 joints obtained by using VINAVIL 2256 L show an excellent resistance to static the good penetration of the dispersion into substrates and the excellent cohesive stregth of the adhesive enable the making of bonded joints that, under shear stress in compression, show a breaking of the wood itself or high percentage of wood fiber 2256 L shows excellent setting time and a good heat is important to point out that when joints are made under direct heat or high frequency drying conditions, changes in the colour of the glue line may be observed.

2 Especially all when using light coloured maintenance of the water resistance (class EN 204 D4) occurs only for modifications that does not lead to an alteration of the pH values of VINAVIL 2256 L. It is possible for example, to add fillers, at the maximum amount of 10% whitout modify the D4 must not be alkaline: calcium sulphate bihydrate and not calcium is important to point out the limited stability of VINAVIL 2256 L during time (3 months) suggesting to avoid long storage period of the product from the dispatch date. Anyway the limited shelf life of VINAVIL 2256 L is an improvement in comparison to the traditional blends with isocyanates or inorganic salts based on VINAVIL 2252 M, 2251 L, 2253 M, 2254 M, 2255 M, 2257 M and 2258 , VINAVIL 2256 L is showing a very good stability ( 6 months) in terms of viscosity / pH change and original performances when stored in the original VINAVIL packaging (125 kg drum with the plastic bag or 1000 l minibulk)

3 At a temperature range between + 10 +30 2256 L is a 48% polyvinylacetate aqueous dispersion used for making mono-component wood adhesives with high water resistance, D4 class according to EN special features of VINAVIL 2256 L include the following :a) excellent water resistance as D4 class according to EN 204b) excellent bond strength on hard, and soft woods, with high percentage of wood tearc) high bond strength and heat resistance according EN 14257 (WATT 91)d) excellent creep resistance according to EN 14256e) excellent setting timeUnitMethodValueSolid content48 2%MVPF 011.
