Alkali resistant fiberglass (AR fiberglass ) is a fiberglass that can be corrosive resistant to alkaline substance, such as cement. It can be used in glassfiber-reinforced cement (GRC), gypsum and other organic and inorganic material. AR FIBERGLASS ROVING
Used for spray-up, winding of mechanical continuous formed GRC and corrosion-proof FRP making.
