Intertherm 3070

Description

Designed specifically for the subsea market, Intertherm 3070 is a two component phenolic epoxy novolac with excellent high temperature resistance and compatibility with cathodic protection.

Where To Use

Specifically intended to provide corrosion protection for subsea equipment such as trees and manifolds. Intertherm 3070 has been designed for use to protect subsea equipment with a maximum steel operating temperature of 185ºC (365ºF).

Characteristics

Intertherm 3070 will not cure adequately below 10°C (50°F). At no time during the application and up to the first 48 hours after application of the final coat must the steel temperature fall below 10°C (50°F). In addition, the relative humidity must not exceed 50% for temperatures in the range 10-20°C (50-68°F), or exceed 80% for temperatures greater than 20°C (68°F).

Intertherm 3070 should be at 15°C (59°F) prior to application. In common with all epoxy coatings Intertherm 3070 may chalk or discolour on exterior exposure. Rate of chalking will depend upon climatic conditions, will have no adverse effect upon anti-corrosive property and will be limited to a thin surface layer.

The recommended total system DFT is 350 microns (14 mils), applied as two coats of 175 microns (7mils). Intertherm 3070 may also be applied as three coats of 120 microns (4.8 mils). The overall coatings scheme thickness must not exceed 450 microns (18 mils)
