MasterSeal 901

METHACRYLATE VINYL ESTER RESIN FOR CRACK INJECTION

Description

MasterSeal 901 is a multi-component, solvent free, water swelling methacrylate vinyl ester based injection system that cures to form a flexible yet solid material with an excellent bond even to wet substrates.

Uses

MasterSeal 901 is recommended for sealing cracks, joints and crevices in concrete, rock and masonry to prevent water ingress. Applications include injection of:

Stabilised cracks and non-moving joints in structural concrete

Concrete construction joints (excluding expansion joints) using MasterSeal 909 injectable hose system. Please refer to MasterSeal 909 for more information.

Advantages

Water molecules held by molecular attraction – captured water does not get transported through capillaries

Unaffected by cycles of swelling and shrinking – continues to perform over long time, despite exposure to wetting and drying cycles

Good bond to damp surfaces – advantage in damp structures

Adjustable reaction time – between 20 and 60 minutes to allow for deep penetration
