PT2114 A/B White Room Temperature Epoxy Laminating Resin
DESCRIPTION
PT2114
is a room temperature curing laminating resin for the construction of
very stable tooling. PT2114 has excellent fabric penetration
capabilities for easy, labor saving use. It exhibits minimum drain on
vertical surfaces, which works well on multiple contoured
configurations. Two hardeners are available for use with PT2114 resin
for different sized laminates. Both offer similar handling properties
and excellent cured physicals.
PT2114 has seem wide usage in applications such as: Hammer Forms,
Assembly Fixtures, Drill Fixtures, Master Gages, Checking Fixtures,
Checking Gages, Duplicating Masters, Sandwich Panels, Prototype
Fabrications and High Strength Laminated Tooling

HANDLING & CURING
Both PT2114 hardeners will provide good cures at ambient temperatures.
With PT2114 Part B, a room temperature cure of 18 to 24 hours, depending
upon shop temperatures, is sufficient to allow handling of the
laminate. When using PT2114 Part B1, particularly 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.

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.
