Polymers

Nalco polymers have been developed to enhance the performance of typical non-polymer shell systems. Addition of Nalco polymers will help increase green strength, shorten drying cycles, improve slurry rheology and increase prime coat adhesion.

Nalco Latrix® 6300 is a moderately stiff polymer that creates Newtonian fluid characteristics in the slurry. This polymer will produce shells that have high strength with superior surface detail. Nalco 6300 will provide better fluidity with Zircon primes. This polymer is a very good choice for back up coat strength.

Nalco Latrix® 6305 is an all-purpose soft flexible polymer that provides great adhesion while creating thixotropic slurry characteristics. The mildly thixotropic slurry properties are well suited for drainage sensitive parts and easier to optimize for robot systems. Shells manufactured with this polymer have high strength and will build thickness quicker. This polymer has very good rheology for prime coat systems.

Nalco Gray Matter polymer is the most recent addition to the polymer list. This polymer was developed specifically for the Gray Matter system that includes colloidal silica, proprietary refractory blend and polymer. Gray Matter polymer is a soft flexible polymer with great adhesion and exhibits Newtonian fluid.
