OSHA Section 1910 106 and 1910 107 2 4 Catalyst Diluents GlasCraft spray up and gel coat systems currently pro duced are designed so that catalyst diluents are not re quired GlasCraft therefore recommends that diluents not be used This avoids the possible contamination which could lead to an explosion due to the handling and mixing of MEKP and diluent In addition it eliminates any problems from the diluent being contaminated through rust particles in drums poor quality control on the part of the diluent supplier or any other reason If however di luents are absolutely required contact your catalyst sup plier and follow his instructions explicitly Preferably the supplier should premix the catalyst to prevent possible on the job contamination while mixing Consult your material supplier to determine whether your solvent or coating contains Halogenated Hydrocar bon Solvents GlasCraft recommends that you contact your solvent 16 WARNING If diluents are not used it should be remembered that catalyst spillage gun hose and packing leaks are poten tially more hazardous since each drop contains a higher concentration of catalyst and therefore will react quicker with overspray and the like 2 5 Uncured Liquid Resin Resin should be stored in a well ventilated building at least 50 feet from your main plant In addition the stor age temperature should not exceed 75 degrees F Safety
