Description

Product Features

Designed for application by trowel or spatula at thicknesses.

Designed for use to rebuilding worn hoppers, chutes, pipe elbows and other equipment subject to aggressive attack from dry solids and slurries.

Excellent adhesion to correctly prepared metal surfaces.

Surface Preparation

All dust and loose material should be scraped away. Oil and grease should be removed with 3M™ Scotchkote™ Cleaner 020. Surfaces should then be abrasive blast cleaned to a minimum NACE No 2/ SSPC-SPC10 Near White Metal, ISO 8501:1, Grade Sa2½ or equivalent with a blast profile of 75 microns (3 mil) corresponding to ‘Medium’. All loose abrasive dust and debris must be blown clear or vacuum cleaned away. Equipment that has become salt impregnated due to service conditions should first be wet blasted, then dry abrasive blasted and checked for presence of salts. This process should be repeated until the salts are removed. Alternatively, surfaces should be warmed with a blow torch or similar to bring salts up to the surface. The surface should once again be blast cleaned. This procedure must be repeated until no further sweating of impregnated salt is evident. On sections of repair which are not required to bond to the Scotchkote Epoxy Ceramic HD Surfacer HG 519 these surfaces should be treated with 3M™ Scotchkote™ Release Agent 035.

Product Mixing

Transfer the entire content of the Part A and Part B containers onto a clean mixing board. Alternatively, measure three volumes of the Part A component and one volume of the Part B onto a clean mixing surface. The two components should be thoroughly mixed until streak free. The use of a small trowel is advisable for easy mixing. The mixed material should be used within 60 minutes of mixing at 20°C (68°F). The time will be reduced at higher temperatures and extended at lower temperatures.

Application Procedures

Application should not be carried out at temperatures below 5°C (41°F) nor when relative humidity exceeds 90% or when the surface to be repaired is less than 3°C (5°F) above the dew point.
