2 Pack Epoxy High Build Primer-Filler for GRP and Composites

 

 

The use of GRP and Carbon Fibre composites in automotive, aerospace and general industrial applications has increased greatly over the past few years. A number of recent applications has seen the use of these composites on high quality visual parts, which has illustrated difficulties in hiding the “tram line” of the fibre mat using conventional primer/finish systems. Difficulties have also been experienced with trying to apply thick films of traditional primers to hide these visual defects with sagging and poor film forming a typical problem. The high actual weight of these thick films is also a disadvantage in both aerospace and autosport applications.

 

Utilising recent developments with low VOC epoxy resin technology and incorporating a new low weight filler medium, we have formulated a 2 component high build primer-filler which solves all the problems encountered.

 

Dry film thickness’ up to 200 microns are readily achieved with a one coat application  using conventional spray equipment and without sagging on vertical surfaces. These film builds effectively fill the surface of the composite moulding and totally obliterate any fibre telegraphing.

 

With a specific gravity of less than 1.00, even at the high builds possible the coating does not add significantly to the overall component weight.
