Assessors adhere a vinyl flooring product to the concrete and seals the edges.
Adhesive mat bond test.
Adhesive bond to the substrate.
Conduct adhesive mat bond testing before beginning the installation.
However rubber adhesive has such good wetting properties that it can also be used very well as a tpe adhesive.
D1875 03 2018 standard test method for density of adhesives in.
This test method is intended for the evaluation of adhesives that can be used to assemble test specimens in accordance with test method d905.
The test is performed by placing 24 inch 600 mm square linoleum or vinyl sheet mats on two adhesive bands one a water soluble adhesive the other a water resistant latex adhesive.
D1489 09 2016 standard test method for nonvolatile content of aqueous adhesives.
Because mat tests rely solely on a visual inspection after 72 hours they are not considered a reliable indicator of the moisture conditions within the slab.
5 3 the number of mat bond evaluation s should be selected that is appropriate for the project and be representative of each type of substrate including trenches grade type of flooring and ambient conditions.
This test determines the compatibility of the nora flooring with the substrate and may provide an indication of the presence of excessive moisture or other contaminates.
Adhesive mat bond tests should be conducted using the adhesive s and material s to be used on the.
D1338 99 2016 standard practice for working life of liquid or paste adhesives by consistency and bond strength.
The edges of the mats are taped to the floor.
Mat bond tests are required.
Adhesive bond performance as measured by resistance to delamination in this test method is suitable for use in adhesive product development manufacturing quality control and monitoring bonding processes.
After 72 hours the mats are removed and the adhesives examined.
This is because the surface of tpe is low energy and therefore very difficult to bond together.
A water droplet test for absorbency of the concrete or cementitious substrate is always recommended when using nora 485 or 685 adhesive.
When in doubt it is recommended that a bond test be conducted.
Standard practice for storage life of adhesives by viscosity and bond strength.
After a thorough sweeping and vacuuming a bond test should be performed.
Rubber adhesive also functions perfectly as tpe adhesive.
Adhesive bond performance as measured by resistance to delamination in this test method is suitable for use in adhesive product development manufacturing quality control and monitoring bonding processes.
Adhesive mat bond testing can identify potential bonding problems and is essential for ensuring the integrity of the flooring system prior to the installation.
This test method is intended for the evaluation of adhesives that can be used to assemble test specimens in accordance with test method d905.
A mat test measures the reliability of an adhesive at the concrete s current moisture conditions.
