PT1554 Aluminum Filled High Temperature Surface Coat
DESCRIPTION
PT1554 is a smooth viscosity aluminum filled epoxy tooling surface coat intended for intermediate high temperature service in a variety of applications. It provides excellent performance in the most demanding industrial applications. It is particularly well suited for tooling that is used in frequent cycling high temperature exposure, where it resists cracking and surface crazing that can be caused by this type of temperature fluctuation. PT1554 resin and hardener mix together very easily, forming a lower viscosity thixotropic material that spreads well and covers corners and projections on the surface nicely. Because of its very creamy, moderately low viscosity, PT1554 works well in applications where fine detail must be duplicated. PT1554 is an ideal general purpose heat resistant tooling surface coat for uses such as vacuum form tools, blow molds, press dies, low production bonding tools and any other application where stability and high performance up to 325°F is required.

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.
