POLY-FAIR F26 is a water resistant, low density polyester-based fairing compound. POLY-FAIR F26 has good adhesion to cured fiber-reinforced
polyester and vinylester laminates. POLY-FAIR sands easily, gives a hard finish after a full cure, yet is not brittle and has good impact strength.
Poly-Fair F26 is supplied as "R" (regular grade), “S” (summer grade), and “W” (winter grade).
