Grinding Sanding and Blasting Asbestos Containing Paints
1. Reference a requested Mare Island Naval Shipyard to examine four
talis for asbestos content and for comparability to the Pfizer Microtalc
Cp 20-30 talc used to make reformulated 24441 paints

sis using dispersion staining : The oil absorptions are based on data
reported by suppliers
which has a

paints are brittle and the shattering action of abrasive removal could

Unfortunately there isno standard analytical method for measuring the
