Quick Overview

Self etching weld-through primer for steel and alloys.

Details

Etchweld is an Etching Primer corrosion protection spray

etchweld is a single pack high-performance self-etching primer that provides ultra-high levels of adhesion to steel substrates.

etchweld protects surfaces from corrosion and promotes superb adhesion for an enormous range of intermediate and topcoats, even increasing the durability of powder coating.

etchweld can be used on some non-metallic substrates but tests should be conducted before use.

etchweld can be used as an adhesion promoter for 2 pack fillers, putties and stoppers. Unlike other etch primers etchweld also provides a weld-through function.

etchweld will also provide high levels of adhesion for coatings applied to non-ferrous substrates such as aluminium and zinc treated surfaces.

etchweld is free of heavy metals and chromates.

How To Use

Aerosol:

Always shake the can vigorously for 2 minutes before use. Non-aerosol product should be stirred thoroughly before use and can be thinned up to 50% with cellulose thinners.

Weld Through:

Ensure that the surfaces are clean and free of contaminants such as corrosion, grease, oil, and paint. Where etchweld is to remain uncoated in weld-through applications such as face-to-face flanges two light coats applied at a distance of around 25 cm are recommended at 7 - 10 minute intervals. Before welding it is important to ensure that full flash-off of solvents has occurred. At an ambient temperature of 20 degrees C, 1 hour is sufficient. In cold conditions allow up to 3 hours.

etchweld can be MIG, TIG, ARC or gas welded. To ensure instant and perfect welds when using spot welding equipment clamp components together initially using clamping equipment such as quick release welder's clamps, mole grips or g-cramps etc. Ensure welder setting is adjusted by testing on scrap steel of identical gauge as the work-piece. MIG welders should be set to produce an even, constant arc, spitting unstable arc is indicative of too high wire speed and can be eliminated by adjustment. After assembly of hollow sections seal seams with seam sealer or further paint coatings, internal sections should be wax injected.

Etch Primer:
Adhesion promoter for:

Cellulose, synthetic, two-pack, water borne, water based, stoving enamel, powder coat, alkyd etc.

Etchweld should be applied as a uniform coating at around 25cm from the degreased, clean surface, and normally allowed to cure for a period of 30 - 45 minutes before over coating, shorter times are acceptable when using most top coats, however for thick film coatings allow up to 1 hour before top coat application. Etchweld will continue to chemically anchor to the substrate under paint films for periods of up to 3 hours. As with any paint system it is good practice to test paint systems at small scale before use.
