INSTRUCTIONS FOR USE

Caution:

Eccostock FPH contains toluene diisocyanate, an obnoxious and

hazardous material. Handling should be carried out in a well-

ventilated area. The use of rubber gloves and face shield is

recommended. Toluene diisocyanate is an irritant to the skin and

mucous membranes, especially eyes and upper respiratory tract.

Please consult the MSDS for FPH and the associated catalyst before

using this product.

For best results, it is preferable that Eccostock FPH liquids be at or

below room temperature.

Weigh out, into separate containers, the required amount of

Eccostock FPH and catalyst as determined by the table below for the

desired density.

Add the catalyst to the liquid Eccostock FPH and mix rapidly.

Mechanical mixing is preferred. Mixing time will be shorter when

the raw materials are warm. Indications of complete mixing are

color changes from a deep to pale pink and temperature increasing

as the exothermic reaction of foam formation begins. Prolonged

mixing will start the foaming and curing in the mixing container.

Free pour the mixed material into the cavity or mold without

scraping.

Foaming will begin shortly after the batch is poured and, depending

upon the batch size, will usually be complete within a few minutes.

For production uses, the foam can usually be removed from the

mold prior to complete cure.

Cure of the higher density foams is generally complete within a few

hours at room temperature. For foams up to about 0.1 g/cc (6

lb/ft

complete the reaction. Friability and an easily powdered surface are

indications of incomplete cure. Post curing conditions depend on

size and configuration. For most purposes a post cure of 4 hours at

93°C (200°F) is adequate.

Molds

Molds are preferably made of aluminum or steel because of high

heat capacity. It is preferable to use a closed mold that will confine

the foam. Small holes or cracks at the top of the mold will allow air

to escape as the foam rises. When the foam completely fills the

mold, it will exert a positive pressure on the mold.

By proper mold design and by pouring a weighed amount in the

mold, it is possible to adjust bulk density. For example, 0.13 g/cc (8

lb/ft

Eccostock FPH and Catalyst to a closed mold.

Eccostock FPH has excellent adhesion to a wide variety of materials.

In the event that release from the mold is desired, silicone mold

releases are recommended. For very small molds small amounts of

petroleum jelly can also be used.

Notes

Under certain conditions, Eccostock FPH will undergo some loss of

solubility of ingredients. This does not apply to the catalyst. Before

use, check each container for clarity. If the material is cloudy, it

should be gently heated to 79°C (175°F) in a well-ventilated oven

and cooled to room temperature or below before use. Containers

should be tightly sealed after use to prevent moisture pick up. The

foaming process is an exothermic reaction.

Consistency of the final density of foam is dependent on

temperature, humidity and mixing technique. The shelf life of this

product is 1 year when stored in unopened containers at

temperatures no higher than 25°C (77°F).

Eccostock FPH at densities less than 0.05 g/cc (3 lb/ft

temperatures above 93°C (200°F). Higher density materials will

withstand higher temperatures.

Cleanup

Methylene Chloride is recommended for the cleanup of mixing

equipment.

Dynasolve 100 is the only recommended solvent powerful enough to

dissolve away cured urethane foams such as Eccostock FPH.
