High – strength fibreglass mesh with a protective coating of special polymers, highly resistant to alkaline environments. Essential for total and partial reinforcement of sealants ( i.e. epoxy, polyurethane, acrylic resins and cement mortar). Provides significant structural reinforcement and prevents cracking from temperature expansion and contraction. Mesh width: 4,5 x 4,5 mm. ± 0.2 Weight (g/m2): raw net 80 g/m2 ± 5% Coating (g/m2): 20 g/m2 ± 5%
