CATALYST SOLUTION DISPENSER FOR A SPRAYING APPARATUS

摘要

A dispenser for dispensing a polymerization catalyst solution into a liquid coating formulation has a cross sectional area "a" given by the relationship: a ? P A [ W / w ] 10-⁶, where "A" is the cross sectional area of the reservoir holding a liquid coating formulation having "W" weight percent of solids; "w" is the weight percent of catalyst in the dispenser; and P is the ratio by weight of the catalyst to the solids desired in the finished coating, in parts per million.
