Surface preparation

METALS

Should be grit blasted to clean surface.

Mechanically abraded and degreased.

Wire brushing is not entirely satisfactory and gives minimal adhesion only.

CONCRETE

Should be free from grease and oil. If necessary, clean with industrial grade degreasing agent. Once clean, steps must be taken to remove laitence; this is best done by using :

  • Mechanical abrasion
  • Acid etching

Concentrated hydrochloric acid (muriatic acid) 1:1 with water, and spreading 0.5 litre of this mixture to each square metre. After the reaction has ceased (about 10 minutes) the area is thoroughly washed and scrubbed with a stiff bristled broom to remove loose sand and allowed to dry for 24 hours.

Painted surfaces

METALS

A proprietary brand paint stripper should be used.

CONCRETE

The surface may be either flame cleaned or mechanically abraded.

 

Processing data

Mixing Ratio 1 part resin to 1 part hardener by volume
Mixing Mix until uniform grey or white
Working life at 25°C 45 minutes
Working life at 25°C 45 minutes
Minimum application temperature 15°C
Minimum Cure Time 12 hours at 25°C
Full Cure Time 4 days at 25°C

IMPORTANT INFORMATION

It is essential that the correct mixing ratio be used and that the Part “A” and Part “B” are thoroughly mixed together before use. Inaccuracies and poor mixing will result in lower physical properties of the cured system and, if the error is sufficiently large, the system may not cure satisfactorily and discolour on ageing.

 

Cured properties (typical)

Maximum operating temperature 70°C
Density 1.45 kg per litre
Tensile Strength 25 MPa
Tensile Bond Strength 10 MPa
Compressive Strength 80 MPa
Flexural Strength 15 MPa
Coefficient of linear expansion 60 mm/mm/°C x 10-6

Properly mixed MEGAPOXY PM will not stain or discolour white or light coloured marble and ceramics.

 

Cleaning

Uncured MEGAPOXY PM can be removed with MEGAPOXY Thinners.

Precautions

Avoid prolonged contact with skin.

  • Wash affected areas with soap and warm water.
  • For further information refer to Bulletin No.100 an Safety Data Sheet for MEGAPOXY PM
