NOURDE TECHNOMELT PA 658 (e) high performance thermoplastic polyamide

is designed to meet low pressure molding process requirements. This

product can be processed at low processing pressure due to its low

viscosity, allowing encapsulation of fragile components without

damage. This material produces no toxic fumes in process and

provides a good balance of low and high temperature performance.

TECHNOMELT PA 658 (e) is well-suited to applications where

excellent adhesion and cold temperature flexibility are demanded.

nourde polyamide low pressure molding.

Application:

Application Temperature: 210℃ to 230℃

Application System: Hotmelt application system with gear pump

· When bonding to a substrate with high thermal conductivity the

use of a specific application temperature is required for good

wetting. Do not heat the product above the specified application

temperature range.

· The substrate surface should be free of dust and cleaned with a

suitable solvent so that there is no fat and oil.

· When the product is not in use do not apply heat, this will

degrade the quality of the product and in extreme cases cause

carbonization. TECHNOMELT PA 658 (e) may absorb moisture

from the air. This will not be apparent in the solid form, but may

cause bubbles on heating and could affect the bond quality. It is

important, therefore, that containers are kept closed and sealed

when not in use.

· The standby temperature for this material is approximately 50℃.

Cleaning:

Carbonized and set (non thermoplastic) material must be removed

mechanically. Removal of the thermoplastic material from the hot

apparatus can be achieved with solvent free cleaning system, such as

Technomelt 0062 (see separate technical information).

Packaging

This product comes granulated, packaged in multi-wall bags containing

40 pounds net.

Storage:

Store in a cool, dry location, with the container tightly closed. When

not in used, this product will have a shelf life of at least 365 days at

temperatures up to +35℃.
