Dosage

Cem-FIL® 61 rovings are used in GRC manufacturing processes with purpose-made GRC equipment. The recommended dosage in sprayed GRC is 5% by weight. The recommended dosage in premix GRC is 3% by weight.

Packaging & Storage

Cem-FIL® 61 rovings are protected by a shrink-wrap polythene film, open at the top, which should not be removed when the product is in use. Rovings are packed on pallets, either with or without carton boxes. Cem-FIL® 61 rovings should be stored away from heat and moisture, and in their original packaging. Optimum conditions are temperatures between 15°C and 35°C and humidity between 35% and 65%. If the product is stored at lower temperatures, it is advisable to condition it in the workshop for at least 24 hours before use to prevent condensation.

Quality Standards

• Cem-FIL® 61 fibers are manufactured under a quality management system approved to ISO 9001.

• Cem-FIL® 61 fibers are not classified as dangerous by the Regulation 1272/2008/EC. For more information, please refer to our Safe Use Instruction Sheet.

• Verified Environmental Product Declaration according to ISO 14025 and EN 15804:2019 available upon request.

• CE-marking and Declaration of Performance (https://www.owenscorning.com/en-us/composites/declaration-of-performance) as fibers for use in concrete and mortar through European Technical Assessment ETA17/0169.
