When it comes to improving results and saving money, the effective mixing of multi-part material is a must for liquid coating processes. This leads to another must-have: a plural component paint mixing system.
A plural component paint mixing system automatically mixes two or more ingredients — like a resin color and a catalyst — at the right ratio. This ensures consistent quality, cuts waste, and saves time compared to hand or manual mixing (also called “hot potting”).
Choosing the right system for your factory or workshop depends on unique factors, such as application, budget, material, and production environment.

Partnership Upgrades Industrial Paint System Staging and Innovation
Dove Equipment, part of ICAFe Companies, partnered with Bradley University to streamline staging for Graco ProMix 2KS and 2KE two-component paint mixing systems — critical equipment for industrial paint kitchens and factory paint mix rooms. Project results not only promise shorter lead times for manufacturers, but they also fuel emerging engineering talent and ongoing innovation.
