Thermally Conductive Acrylic Interface Pad 5571
Application Techniques
• To obtain optimum thermal conductivity, good surfaces for wet out are required. For better contact,
clean, dry and well unied surface conditions are recommended. Typical surface cleaning solvents are
isopropyl alcohol and water (rubbing alcohol) or heptane. Note: Be sure to follow manufacturer’s safety
precautions and directions for use when using solvents.
• Ideal application temperature range is from 0°C to 40°C. Initial application to surfaces at temperatures
below 30°C is not recommended because the pad becomes too rm to be wet out readily. However,
once properly applied, low temperature holding is generally satisfactory.
Heat Resistance
*Note: The end use customer application, design & verication testing will determine the nal in use eective temperature range based
on each application’s environmental conditions.

Certicate of Analysis (COA)
The 3M Certicate of Analysis (COA) for this product is established when the product becomes commercially available
from 3M. The Technical Data Sheet (TDS) technical information, test methods and data should be considered represen-
tative or typical only and should not be used for specication purposes. The Technical Data Sheet (TDS) information is
based on a limited set of test results and do not reect the COA specication limits. Final product specications and
associated manufacturing facility testing methods used for the commercialized product are outlined in the products
Certicate of Analysis (COA) that is provided upon request or with the products shipment.
The COA contains the 3M specications and test methods for the products performance limits that the product will be
supplied against. The 3M product is supplied to 3M COA test specications and the COA test methods. Contact your
local 3M Technical Service representative for the COA for this product.
