F. A.Q.s
Durometer Hardness
Durometer hardness is a property presented on technical
data sheets that shows how hard the resin is in the cured
state. A durometer gauge is the actual measuring device
consisting of a small drill or blunt indentor point under
pressure. Different measurement scales are used for
different materials depending on how soft or hard the
material. The following chart compares three (3) different
graduated measurement scales and relates hardness values
to some common objects as well as Loctite® brand products.
The higher the number within each scale, the harder the
material. Shore readings are typically used for plastics.
Shore A is for softer materials; Shore D is for harder
materials. Rockwell readings are typically used for metals.

Mathematical Conversions
The following are some common conversions that might be
helpful when utilizing Loctite® products:
• 1 milliliter (ml) = 1 cubic centimeter (cc)
• 1,000 ml = 1 liter
• 29.5 ml = 1 fl. oz.
• 3.78 liters = 1 gallon
• 473 ml = 1 pint
• 454 grams = 1 lb.
• 947 ml = 1 quart
• 1 kilogram = 2.2 lbs.
•
•
•
•
•
• Square Inches to Square Feet: ÷ by 144
• Square Feet to Square Inches: x by 144
• In./lbs. ÷ 12 = ft./lbs.
• Ft./lbs. x 12 = in./lbs.
• 16 in. oz. = 1 in. lb.
• 192 in. oz. = 1 ft. lb.

Length x Width x Bondline Thickness x 16.4 = cc/ml
requirement per part
Diameter x Engagement Length x Bondline Thickness
(on radius / per side)
x 3.14 x 16.4 = cc/ml requirement per part
Area (3.14 x R2) x Potting Depth x 16.4 = cc/ml
requirement per part
= specific gravity x 0.99823
= centistokes x density (at a given temp.)
degrees F - 32 x 0.556 = degrees C
degrees C x 1.8 + 32 = degrees F
grams ÷ specific gravity = cc (ml)
cc (ml) x specific gravity = grams
