7. SHELF LIFE

If stored in the original, unopened containers at cool (below 30°C) and dry place WINDFIX BWR has a shelf life of 9 months from the date of manufacture. 

2. APPLICATION METHOD

  • The surfaces should be free from dust, oil and grease. They should be dry and properly leveled. For best results, roughen the surfaces to be bonded.
  • Ensure adhesive container is stirred well before use.
  • Mix the WINDFIX BWR adhesive with WINDFIX HARDNER in the ratio of 100:4 (4 to 5) by weight and mix it thoroughly.
  • WINDFIX BWR adhesive should be applied as a thin, even coating to one surface only.
  • FOR PLY TO LAMINATE: Before allowing adhesive to dry, bring both the surfaces in contact, align properly and start pressing from one side by using wet squeezed cloth to avoid bubbles and ensure uniform contact.
  • FOR WOOD TO WOOD: Before allowing adhesive to dry, bring both surfaces in contact and align properly. To get best results keep them pressed for 24 hours. 
  • Excess adhesive that oozes out from edges should be wiped off with a wet squeezed cloth. 
  • Pressure can be applied by using Clamps, Weight, Cold Press, Hot Press, Roller Press etc. 
  • If required, pressure can be released after 3 to 4 hours and then bonded assembly can be processed further.
