AR chopped strands for Repair Mortars and premix GRC used as a component of repair mortars to enhance their perfor china

PRODUCT DESCRIPTION

GRC-60 is a high integrity AR glass fibre chopped strand designed for premixing with other materials and the resulting mix is formed by vibration casting or other processes into molded GRC components.

It can also be used as a component of repair mortars to enhance their performance.

PRODUCT APPLICATION

The high integrity of the product makes it suitable for use in a variety of production processes including vibration -casting, pumping, spraying, or dry-blending with other materials.

GRC-60 chopped strands are designed for ease of incorporation even at high dosage and remain integral duringmixing. It is used in the manufacture of repair mortars, standard GRC components such as drainage channels or meter boxes, or in architectural applications such as decorative screen walling and ornate moldings.

GRC-60 hydrophobic behavior makes the mix more fluid and that ensures better compaction and easier release of trapped air.
