As a sealant, it should have lower viscosity and higher adhesion. The
viscosity is lower, which can prolong the use time and reduce waste. The
adhesiveness is better, and it can be attached to the adhesive object, which
greatly improves the firmness.
Do I need to do a test before using the sealant? This is the doubt of many
users! If conditions permit, a small-scale test should be carried out to see if
the specific effect is good or not.
Test for physicochemical properties
Check the color and state of the adhesive, whether there are impurities;
see if the density is large or small, whether it is suitable for use in the
industrial field; test the viscosity and curing speed to obtain more reliable
data.
Test various properties
Understand the structure and formula of the main agent and curing agent of
the adhesive to see if it meets the requirements of the object to be bonded;
test all aspects of performance to see if it can perform stably. In addition,
it is necessary to understand the temperature, humidity and pressure of the use
environment to see which environment can exert greater value. Cooperate with
powerful suppliers, more assured, such as TENSAN, focus on sealant research,
provide customized sealant application solutions, widely used, can be used in
new energy, military, medical, aviation, ships, electronics, automobiles,
instruments , power supply, high-speed rail and other industries.
Tested for tensile properties
When the sealant is cured, it can resist stretching and tearing of a
certain strength, and will not break or fall off easily. Learn about the
tensile properties in advance to see if they can meet your actual needs. When
the tensile resistance of the adhesive layer is not too strong, after being stretched,
it may cause the edge of the adhesive layer to crack, slowly expand to the
entire adhesive surface, and lose its use value.
