WEST SYSTEM
#105 Epoxy Resin

#105 Epoxy Resin is the heart of the WEST SYSTEM family of products. A clear, light amber, low-viscosity liquid epoxy resin, this product is formulated for use with West System hardeners. With roller application, it possesses excellent thin-film characteristics in flowing out and self-leveling without fish-eyeing. Cures quite clear in a wide temperature range and can be sanded and shaped afterward. Works as an excellent adhesive when mixed with WEST SYSTEM fillers to reduce sag and bridge voids. We strongly recommend the use of WEST SYSTEM dispenser pumps.

                    Comments about #105 Epoxy Resin:

                    Over the years I've used every West System product for many applications. The biggest was repairing thousands of gelcoat bubbles on my 4 year old Yamaha 30 sailboat. (When the boat was commissioned the yard fails to apply epoxy primer before anti-fouling paint.) The hull was an unbelievable mess. I had another yard sandblast it below the waterline, which removed all the gelcoat, and dug out the thousands of bad spots. I wanted it fixed right, but, couldn't afford to have the yard do the repairs. I'd never used West, but the yard owner said that West System was the only way to go!

                    I coated the raw glass with unthickened West System Epoxy Resin. When it cured I sculpted thickened resin to fill all the "cavities". Then I sanded it, did a final fairing with thickens West, and sanded it again to a perfectly true racing bottom. I'm happy to report that "Bushido" is still going strong, is residing in Kaneohe Bay, and, after 30 more years in Hawaiian waters has had no problems with the repairs! I actively raced it there, back in the day, (24-27 races a year) with a seasons point record of 1st, 2nd, or 3rd for 8 of the 9 years! Now I'm doing another major repair on flood damage to the hull of my Capri 30...... Again, West System is my only choice!
