The edges of the mats are taped to the floor.
Adhesive mat bond test.
Adhesive mat bond testing can identify potential bonding problems and is essential for ensuring the integrity of the flooring system prior to the installation.
However rubber adhesive has such good wetting properties that it can also be used very well as a tpe adhesive.
A water droplet test for absorbency of the concrete or cementitious substrate is always recommended when using nora 485 or 685 adhesive.
This is because the surface of tpe is low energy and therefore very difficult to bond together.
Conduct adhesive mat bond testing before beginning the installation.
Assessors adhere a vinyl flooring product to the concrete and seals the edges.
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.
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.
The number may also be determined by the responsible party or specified by the end user general contractor and architect flooring.
D1875 03 2018 standard test method for density of adhesives in.
Residues from dissipative curing compounds and parting compounds that allow separation of tilt up slabs must be removed prior to applying adhesives.
But bonding thermoplastic elastomers is a challenge in itself.
Rubber adhesive also functions perfectly as tpe adhesive.
This test method is intended for the evaluation of adhesives that can be used to assemble test specimens in accordance with test method d905.
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 bond to the substrate.
D1338 99 2016 standard practice for working life of liquid or paste adhesives by consistency and bond strength.
When in doubt it is recommended that a bond test be conducted.
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.
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.
Standard practice for storage life of adhesives by viscosity and bond strength.
This test method is intended for the evaluation of adhesives that can be used to assemble test specimens in accordance with test method d905.
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 tests should be conducted using the adhesive s and material s to be used on the.
D1489 09 2016 standard test method for nonvolatile content of aqueous adhesives.
After 72 hours the mats are removed and the adhesives examined.
