duoMatrix–C - is new polymer additive for concrete that greatly enhances the physical and performance characteristics:

Performance In Overdrive - Matrix–C greatly reduces water/salt absorption and virtually eliminates microcracks. Matrix-C also enhances freeze/thaw, chemical and UV resistance.

Production In Overdrive - Matrix-C eliminates the need for the usual 7 day post cure. Casting can be cycled faster, making your operation more productive.

 

GFRC To The Max... Matrix-C was made for glass fiber reinforced concrete applications and can be cast, laid up or sprayed - Ideal for making strong, lightweight architectural elements & building facades.

Gypsum Casting

duoMatrix-G is a new polymer additive system for alpha gypsums that greatly enhances physical and performance properties:

Be More Productive - Matrix-G castings can be demolded at a rate 4X faster.

Stronger - Matrix-G greatly improves the physical strength of castings. Matrix-G can be cast solid or mixed with chopped fiberglass. This means far less breakage vs. gypsum.

Lighter - Matrix-G and fiberglass matting or chopped strand will yield elements that are ultra-light and ultra-strong. Matrix-G can be laid up by hand or machine sprayed.

Weather Resistant elements are highly resistant to water, freeze/thaw and UV light.

Versatility - Matrix-G is ideal for adding metal powders to duplicate the look of real metal (i.e., bonded bronze), or other fillers such as calcium carbonate to duplicate the look of real marble. Matrix-G can also be pigmented or painted to achieve vibrant color effects.

Matrix NEO

Matrix Neo is a new polymer modified gypsum that is easy to use, very strong and very versatile.

NEO is mixed 2A : 1B by volume and can be cast solid or mixed with fiber for laying up to make thin, strong elements. Achieve a variety of surface finishes / effects with pigments & fillers including realistic cold cast metal, stone, terra cotta, marble, etc.
