High Strength Solvent Free Epoxy Resin Patching Mortar

Description

Estocrete WR is a two parts epoxy resin mortar, which is cured chemically. It has excellent compressive strength, which cured with negligible shrinkage and applicable in damp and underwater condition.

Estocrete WR has good chemical resistant.

60 to 70% of final compressive strength will be achieved after about 48 hours curing at 30oC.

Estocrete WR has been tested in accordance to BS 6319 : Part 2 on Compressive Strength Test, BS6319 : Part 3 on Flexural Strength Test, BS6319 : Part 7 on Tensile Strength Test, ASTM D4541 on Tensile Adhesion Strength Test and complied with the specification in this data sheet.

Physical Properties

Application Instructions

Surface Preparation

Substrate shall be thoroughly clean. It must be free from oil, grease dust and surface contaminants.

Degrease steel work if necessary.

Surface to be fixed with tiles or bricks shall be mechanical abraded and cleaned with clean water.

Priming

Under normal circumstances, no primer is required.

Mixing

Mix all of Part A and Part B in a mixing pail with a low speed drill and mixing paddle. The mixing shall be at least 5 minutes until a consistence homogeneous mortar is achieved.

WATER SHALL NOT BE ADDED.

Application

On overhead and vertical situations, Estocrete WR shall be applied between 3mm – 15mm thick in one application.

A damp or heated trowel shall be used to obtain smooth surface.

For underwater application, the mixed Estocrete WR shall be carried in plastic bag to work area and shall only be contacted  with water until the point of application. A small quantity shall be pressed firmly into position to ensure all water is being expelled from the substrate. It shall be protected from scouring and running water until it is cured.

Cleaning

Tools, etc can be cleaned while the mortars are still uncured with water or detergent solution. Cured mortar can be removed with wire brush after heated with a gas torch.
