One Step Formulation (Constant Low Humidity Conditions)
1. Combine DPM-1002 resin, plasticizer and "thixcin" R. Blend with a
high shear mixer until a temperature of 130-140F. is reached.
2. Add "Silane" and blend in with slow speed mixer. Add remaining
ingredients and blend the entire formulation with a slow speed mixer.
3. Pass over a tight three roll mill until a Hegman value of six or less
is indicated.
4. Package in moisture-impermeable co
配制方法: Grind on a three roll mill with minimum air exposure. Store in moisture-impermeable containers.
Ideally, the activator should be prepared under dry air, dry nitrogen or vacuum. Totally enclosed equipment might be suitable if adequate grinding can be obtained.
Step 2 Process the remaining components of the formulation with a procedure identical to that used in the one step technique.
Step 3 Combine proper proportions of materials produced in Steps 1 and 2 by blending with a slow speed mixer under a dry atmosphere.
Package in containers which will prevent moisture contamination during storage. Aluminumfoil lined cardboard cartridges appear to be satisfactory.
