Colloidal Silica

Colloidal Silica, .5 Gallon from MAS EPOXY
Fumed Colloidal Silica (also known as CAB-0-SIL) Use when an extremely hard solid with high density is needed, i. e. structural bonding, filling and filleting. Add strength to a top coat by using a small amount of Colloidal Silica ( about a tablespoon per 4 ounces). This will add strength and finish absolutely clear.

406 Colloidal Silica Filler - 6 OZ from WEST SYSTEM
406 Colloidal Silica is a thickening additive used to control the viscosity of the epoxy and prevent epoxy runoff in vertical and overhead joints. 406 is a very strong filler that creates a smooth mixture, ideal for general bonding and filleting. It is also our most versatile filler. Often used in combination with other fillers, it can be used to improve the improve strength, abrasion resistance, and consistency of fairing compounds, resulting in a tougher, smoother surface.

Mas Slow Hardener, 1 Quart from MAS EPOXY
When used in conjunction with MAS Epoxy Resin it provides high reactivity and an extended gel time which allows for controlled and extended application periods. Special features exhibited by this product include blush free surfaces, good ultraviolet stability, smooth finishes in cured films, excellent osmotic resistance, and the ability to cure under high humidity. The low viscosity of MAS Slow Hardener (200-250 poise) when mixed with MAS resin is ideal for fast wet-out of reinforcing fabrics.

Mas Cell-O-Fill Filler, 1 Quart from MAS EPOXY
Derived from all natural alpha cellulose, the fibrous ribbons create a matrix with the epoxy and help reduce sagging and slumping. Used in place of Colloidal Silica, it will not billow in the air like silica and you will need half as much to create the same thickness.

Mas Medium Hardener, 1 Quart from MAS EPOXY
MAS Medium Hardener is a polyamine blend intended for moderate reactivity. We recommend this hardener when "overnight" sandibility is more important than continuous laminating and open time (as provided by MAS Slow Hardener) MAS Medium will also provide a beautifully smooth void free finish, with great resistance to milking out during application and fogging in critical clear coating applications. STORAGE LIFE: A minimum of 12 months in a sealed container at ambient temperatures.

Mas Fast Hardener, 1 Quart from MAS EPOXY
The low viscosity of Fast Hardener allows for quick wet-out of the heavy reinforcing fabrics often used in repair applications. Additionally, the superior bonding strength of Fast formulas is ideal for high strength secondary bonding applications such as structural tabbing and repair of laminations. The rapid cure time of Fast allows overnight curing in low temperature conditions. of formula unless rapid application techniques are incorporated. Always maintain a 2:1 ratio of resin : hardener.
