Description

A two component epoxy anti-corrosive primer.

Technical Information

ntergard 291 is preferred for use with systems for chemical environments where zinc based materials can be subject to attack in both acidic and alkaline conditions.
The maximum overcoating interval will be dependent upon the integrity of the exposed film. A film of 75 microns (3 mils) dry film thickness will normally be overcoatable after 6 12 months exposure (depending upon the corrosivity of the environment) provided it is adequately cleaned and any areas of mechanical damage repaired.
Over-application should be avoided as thick films will not be as good a substrate for topcoat adhesion after ageing as those at the specified thickness. When using as a blast holding primer avoid over-application as thick films may suffer from cohesive film splitting if subsequent coats are also over-applied. Over-application of Intergard 291 will extend both the minimum overcoating periods and handling times, and may be detrimental to long term overcoating properties. When applying Intergard 291 by brush or roller, it may be necessary to apply multiple coats to achieve the total specified system dry film thickness. This product will not cure adequately below 5°C (41°F). For maximum performance ambient curing temperatures should be above 10°C (50°F).
Surface temperature must always be a minimum of 3°C (5°F) above dew point. In common with all epoxies Intergard 291 will chalk and discolour on exterior exposure. However, these phenomena are not detrimental to anti-corrosive performance. Intergard 291 is not designed for continuous water immersion. Where a durable cosmetic finish with good gloss and colour retention is required overcoat with recommended topcoats.
Note: VOC values are typical and are provided for guidance purpose only. These may be subject to variation depending on factors such as differences in colour and normal manufacturing tolerances.

Where To Use

Intergard 291 is designed for application to correctly prepared steel. However, it is also possible to apply over approved prefabrication primers. Further details of these can be obtained from International Protective Coatings.
