PT1158 White Room Temperature Epoxy Surface Coat
DESCRIPTION
PT1158 is a white epoxy surface coat system that has very good handling and cured properties. It is a thin paintable viscosity material, so it applies easily and quickly, and it has sufficient thixotropy to hang on contoured or vertical surfaces. It can be applied quickly to large areas, and at the same time, it will pick up fine detail with ease. The cured product has tough, durable characteristics, for long dependable service. It can be sanded or scribed without chipping, and it withstands impact well. PT1158 is a good candidate for tooling or parts that require a good surface finish, tough cured properties and long term stability.

HANDLING & CURING
The mixed viscosity of the PT1158 system is quite thin, yet smooth and
creamy. This allows it to be applied easily in a uniform layer over the
model. With room temperature surface coats, the normal procedure is to
apply two surface coats, allowing the first to firm up before applying
the second coat. When constructing laminated tools, the two coats will
allow the completed tool to be sanded or filed without breaking into the
laminate and exposing fibers on the face of the tool. The surface coat
will be cured sufficient for handling when the laminate is cured.

SAFETY & HANDLING
PTM&W epoxy products are made from raw materials carefully chosen to minimize or even eliminate toxic chemicals, and therefore offer the user high performance products with minimum hazard potential when properly used. Generally, the PTM&W epoxy resins and hardeners will present no handling problems if users exercise care to protect the skin and eyes, and if good ventilation is provided in the work areas. However, all epoxy resins and hardeners can be irritating to the skin, and prolonged contact may result in sensitization; and breathing of mist or vapors may cause allergenic respiratory reactions, especially in highly sensitive individuals. As such, avoid contact with eyes and skin, and avoid breathing vapors. Wear protective rubber apron, clothing, gloves, face shield or other items are required to prevent contact with the skin. In case of skin contact, immediately wash with soap and water, followed by a rinse of the area with vinegar, and then a further wash with soap and water. The vinegar will neutralize the hardener and lessen the chances of long term effects. Use goggles, a face shield, safety glasses or other items as required to prevent contact with the eyes. If material gets into the eyes, immediately flush with water for at least 15 minutes and call a physician. Generally, keep the work area as uncluttered and clean as possible, and clean up any minor spills immediately to prevent accidental skin contact at a later time. Keep tools clean and properly stored. Dispose of trash and empty containers properly. Do not use any of these types of products until Material Safety Data Sheets have been read and understood.
