Can I mix two-pack coatings from different suppliers if they have the same mixing ratio?
No! Each product is carefully balanced with regard to amount of resin in the base, and amount of curing agent in the hardener. Even if two-packs from different suppliers have the same mixing ratio (for example, a 4:1 ratio) the level of hardener to resin can be completely different. The “Part A” in each two-pack kit specifically requires the exact amount of hardener present in its own “Part B” in order to properly cure. In fact, the same principle applies to different products with the same mixing ratio from the same supplier! Therefore, if you attempt to mix apparently similar products from different suppliers, you run the very high risk of application or coating failure due to incorrect resin/curing agent ratios.
