DO YOU PREFER AMMONIATED LATEX OR "e;NO"e; AMMONIA LATEXES FOR MAKING MOLDS?
We prefer higher ammonia concentrated latex. One of the basic reasons is that latex preserved with alkali has a marked tendency to be "e;sticky"e; and "e;tacky"e;. Another reason is that non-ammoniated latex has a tendency to absorb water so that evaporation is very slow. This means long waits between coats. Our #80 ammoniated latex is designed to coat about every hour as opposed to the de-ammoniated latexes.
