Intergard 405

Description

A two component epoxy sealer coat, pigmented with micaceous iron oxide. Formulated on
proprietary polymer technology, which provides rapid cure and overcoating, even at low
temperatures.

Where To Use

To provide efficient sealing of zinc silicate primers in order to prevent pinholing of subsequent topcoats. Can also be used for sealing zinc and aluminium metal spray either as a single coat system or prior to overcoating with a suitable topcoat where required.

Intergard 405 is suitable for use as part of a coating system in a range of highly corrosive
environments, including offshore structures, petrochemical and chemical plants, bridges, refineries, pulp and paper plants and power stations.

Technical Information

Intergard 405 is formulated at a viscosity suitable for penetration and efficient sealing of freshly applied zinc silicates such as Interzinc 12 and Interzinc 22. It is also suitable as a travel or weathering coat for zinc epoxy primers. This product must only be thinned using recommended International GTA220 thinners. The use of alternative thinners, particularly those containing ketones, can severely inhibit the curing mechanism of the coating. Best results will be achieved at temperatures above 0°C (32°F). Over-application will result in sagging as Intergard 405 has been designed to give maximum flow characteristics. Excessive film thickness may lead to splitting of the film when overcoated with high build systems. 

Intergard 405 is not designed as a blast holding primer and when used in such circumstances is unlikely to give long term corrosion protection. Intergard 269, Intergard 251 or Intercure 200 are preferred alternatives in these circumstances. Intergard 405 has been specifically designed to provide superior properties of curing flow in order to provide efficient sealing of zinc silicate primers at temperatures less than 10ºC (50ºF). Intergard 405 can also be used over zinc or aluminium metal spray to seal off any porosity and ensure maximum corrosion life. When applying Intergard 405 in confined spaces ensure adequate ventilation. In common with all epoxies Intergard 405 will chalk and discolour on exterior exposure. However, these phenomena are not detrimental to anti-corrosive performance. 

This product is frequently used as a 'travel coat' prior to final overcoating on site. To ensure best extended overcoating properties ensure over-application does not occur and that the surface is fully cleaned of any contamination which may be present in the surface texture due to the coarse nature of the micaceous iron oxide pigmentation. Absolute measured adhesion of topcoats to aged Intergard 405 is less than that to fresh material, however, it is adequate for the specified end use.
