TECHNICAL DATA SHEET
Product Name: Norst® PB-800
Proprietary butyl compound of 100% soilds
A primary application is the improvement of strength and elasticity in hot melt adhesives.
Hot melt sealants
Pressure sensitive adhesives
Builds strength in hot melt adhesives
Stops cold flow and migration when combined with polybutenes, butyl rubber, unoxidized asphalts
Ball and ring of most systems is not affected
Melt viscosity is low relative to its melt point and solid point
Builds strength in asphalts
Chemical resistance comparable to polyisobutylene
200,000-240,000 cps at 350ºF using Brookfield HBT Model with a no. 6 spindle at 20 rpm
Compatible with aliphatic resins, oils, asphalts and polybutenes, butyl rubber, ethylene propylene rubbers, etc.
Light amber to light brown
