Epoxy Hardners 
 
Mixing ratios of General Purpose Hardeners are with reference to a standard liquid basic resin (B-11). Where hardeners are intended for use with a specific resin, the ratio refers to that resin which is specifically indicated
 

LINEAR ALIPHATIC AMINES AND ADDUCTS COLD SETTING
DENOMINATION	PHYSICAL FORM	VISCOSITY  AT 25OC cps	AMINE VALUE eq/kg	MIXING RATIO	RECOMMENDED APPLICATION
LAPOX K-7	Liquid	<10	27.60-29.10	100:10-12	General purpose reactive hardener with high vapor pressure
LAPOX K-6	Liquid	<10	---	100:10-12	General purpose reactive hardener with lower vapor pressure.
LAPOX K-52	Liquid	3400-5000	13.60-14.20	100:20	Very reactive general purpose hardener. Short pot life, high exotherm.
LAPOX K-48	Liquid	200-300	---	100:18	Very reactive general purpose hardener. Short pot life, high exotherm.
LAPOX K-63	Liquid	4800-7200	--	Variable  w/ C-52 / K-88	Used in cable jointing applications together with  K-88 to adjust reactivity.
CYCLOALIPHATIC AND BRANCHED ALIPHATIC AMINES AND ADDUCTS COLD SETTING
DENOMINATION	PHYSICAL FORM	VISCOSITY  AT 25OC cps	AMINE VALUE eq/kg	MIXING RATIO	RECOMMENDED APPLICATION
LAPOX K-54	Liquid	2900-3600	7.10-7.40	100:35	General purpose hardener of high reactivity used for light color coatings with high chemical resistance
LAPOX L-106	Liquid	<10	12.40-12.70	100-22	Very low viscosity hardener used for grouting of cracks and for solvent free coating floor toppings
