PT2125 White, Medium Viscosity Room Temperature Laminating System


PT2125 is a white room temperature service laminating system for use in producing durable and stable industrial tools. The medium viscosity of PT2125 is designed to provide very good penetration of tooling fabrics, and at the same time, exhibit minimum drain on vertical or contoured surfaces. PT2125 is a high quality, non-toxic material which has excellent moisture, chemical and impact resistance for a great many applications.
Typical Applications: Hammer Forms, Assembly Fixtures, Duplicating Masters, Sandwich Panels, Hi-Strength Laminated Tools, Router Templates, Master Gages, Checking Fixtures/Gages, Drill Fixtures

The PT2125 system will provide good cures at ambient temperatures. In normal conditions, a room temperature cure of 18 to 24 hours, depending upon shop temperatures, is sufficient to allow handling of the laminate. In colder temperatures, at least 24 hours cure will be required to develop good properties. Full cure can be accelerated by 1 to 2 hours at 150 o F after an overnight cure at ambient temperature. Heat curing will usually increase shrinkage somewhat, so care should be taken to control the heat cure to minimize stress buildup in the tool.

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.
