The data sheet for high temp says 100:35 but mentions a different product altogether.
so may be a copy paste error.
MIXING RATIO 100 p.b.w. Epoxy Rapid Repair Resin
             35 p.b.w. Epoxy Rapid Repair Hardener

The high temp product illustrations show 100g hardener and 400g resin which implies a 100:24 ratio.
Which ones are in error. Illustration, datasheet or both.

Hi,

The correct mix ratio for our Very High Temperature Epoxy Resin is 100:35 parts (by weight).

Thanks for pointing out the typo in the TDS, that should have read Very High Temperature Epoxy Resin and Hardener, not Rapid Repair Resin. The mix ratio is correct. I've updated this datasheet now.

The photo on the site is out of date (the mix ratio did used to be 100:25); I'll get a new one done very soon. The packaging you'll receive shows the new mix ratio of 100:35. If in doubt, always go with the mix ratio shown on the packaging.

I hope this clears it up and thank you for pointing this out.

All the best, Matt
