Description
Sylvic R27 is a resorcinol phenol formaldehyde resin that is used in conjunction with the liquid hardener Sylvic L4/ Slyvic L5 and is recommended for use in laminating and fingerjointing soft and hard wood lumber
Application
The recommended ratio of resin:hardener is 3:1 by weight with an allowable range of 2.8 –3.2 parts resin to 1 part liquid hardener by weight. This ratio is critical to the performance of the adhesive and must be checked quantitatively during production.If batch mixing the hardener should be added to the resin and stirred for 2 – 3 minutes until a smooth mix is obtained. Mixing can be carried out in containers of steel, glass, wood or in galvanised or tinned vessels. Copper and brass must not be used. On NO account should leftover glue be incorporated into the next
