Epoxy Surface Coats  | Our services and products include epoxy laminating resins, casting, adhesives, and rapid prototyping. Review the products and services we offer as you explore our site, and consider us for your applications. We have the technical knowledge to help make our products work best for you. Epoxy surface coats are paste-viscosity resins designed to be applied by brush or squeegee to a model or pattern to function as the surface of the cured tool. They generally possess handling properties that facilitate easy mixing and application, and their cured properties provide a tough, durable surface that can be sanded or scribed with ease. Epoxy laminating resin systems consist of both unfilled and filled products that are intended for use with reinforcing fabrics to construct high performance composite tooling prototype and/or production parts. The pertinent handling and cured properties of these systems are listed below to aid in selecting the right material for your application. Leading supplier of epoxy laminating resins |  | | |  | We specialize in water clear urethanes, and polyester filler paste. You can contact us regarding any of our products such as polyester filler paste. Catalytic-cure polymers, like polyesters, will cure with any amount of catalyst added. A catalyst just starts the reaction. The more catalyst, the shorter the pot life and faster the cure time. Epoxies and urethanes, with a few exceptions, are designed to cure at an exact mix ratio, which allows each molecule of resin will crosslink with a molecule of hardener. Off-ratio mixes result in excess resin or hardener molecules that have nowhere to attach, which results in deteriorated properties. It is important to note that the target mix ratio should be the one that is published. The tolerance range allows for slight errors in measurement. To intentionally measure off ratio is never advised. Some epoxy hardeners are formulated to be “variable-ratio hardeners”. The published ratios for these hardeners will show a range of acceptable mix ratios. |  |

Epoxy surface coats are paste-viscosity resins designed to be applied by brush or squeegee to a model or pattern to function as the surface of the cured tool. They generally possess handling properties that facilitate easy mixing and application, and their cured properties provide a tough, durable surface that can be sanded or scribed with ease. Laminating Systems:
Epoxy laminating resin systems consist of both unfilled and filled products that are intended for use with reinforcing fabrics to construct high performance composite tooling prototype and/or production parts. The pertinent handling and cured properties of these systems are listed below to aid in selecting the right material for your application. Epoxy N-Fusion Systems:
These systems feature products designed for the fabrication of parts and structures and tooling by the Vacumm-Assist Resign Transfer Method (VARTM).
Casting Resins:
Epoxy casting resins are versatile products that can provide an excellent solution to a variety of industrial applications. They generally contain a filler of some type that is provided to produce specific handling or cured properties. These fillers can be of a metallic nature, or of a variety of non-metal fillers. The specific fillers can provide lower shrinkage, higher compressive strengths, better metal forming properties, or other characteristics suited to a particular use. A variety of systems, for both room temperature as well as high temperature service are listed here with different hardeners to more closely match the material to the application. Adhesives:
We manufacture a wide variety of structural adhesives for industrial applications. Listed here are a number of stock products that include a broad range of properties. Many of our adhesives are tailored to specific uses and individual applications. If you have a requirement that cannot be fulfilled by these standard products, let us select or design a high performance adhesive that works for you. Specialty Systems:
These products are paste viscosity filled epoxy systems designed for use in a number of applications. Generally, they have been formulated for a particular purpose, and have characteristics suited to such use. The individual descriptions outline the intended use of each, and describe their suitability to the task.
