This test method covers measurement of the comparative tack of pressure-sensitive adhesives by a rolling ball and is most appropriate for low-tack adhesives.
Where test liquids other than reagent water are used, the actual liquid used is reported. This test method covers testing of the components of mechanical pump dispensers spray or flow types for compatibility with consumer-type products. It covers the measurement of both the sstm angle of contact and the angle of contact after a defined elapsed period of time may be measured.
Since the characteristics that render a material resistant to creep under the condition of test are not yet completely known, the details of the procedure considered herein are those known to have important influences.
Sealants requiring slight heating to facilitate extrusion from the cartridge or gun are also described by this test method. This test method measures the angle of contact when a drop of liquid is applied to the surface of a specimen of paper.
VISCOSITY CUP ASTM D D IMMERSION
This test method covers determination of the temperature at which a specified needle penetration occurs when specimens are subjected to specified controlled test conditions. Since other equally important characteristics may be discovered in the future, the recommended details are largely advisory in nature.
A different procedure using an automated instrument for measuring angle of contact can be found in ASTM D The test method is not recommended for ethyl cellulose, nonrigid poly vinyl chloridepoly vinylidene chlorideor other materials having a wide Vicat softening range. For such adhesives, tack may be measured as the force required to separate adhesive and adherend at the interface shortly after they have been brought into contact under a defined load of known duration at a specified temperature.
This test method may be used with any substrate of interest, which can be cut to dimensions compatible with the equipment used. On very rough or porous surfaces, the sensitivity of the test may be significantly decreased. These test methods cover the determination of the transfer efficiency of spray-applied coatings under general plant conditions. The operator and the spray-application equipment-operating conditions during the transfer efficiency measurement should be representative of normal operating conditions.
When properly conducted, the test will enable detection of molecular layers of hydrophobic organic contaminants. The procedures covered are as follows:. Test periods depend upon the reasonable life expected from the material in service. This test method covers the determination of the creep properties of adhesives for bonding metals when tested on a standard specimen and subjected to certain conditions of temperature and compressive stress in a spring-loaded testing apparatus.
These test methods have not been adopted by federal regulatory agencies for demonstration of compliance with air pollution regulations such as VOC, HAPS, etc.
Procedures A and C are not recommended for films less than 0. Other liquids including printing inks, writing inks, adhesives, oils, and coating materials may be used upon agreement of those involved in the testing being done.
This test method covers a procedure for the determination of the tack-free time property of single- and multi-component elastomeric sealants commonly used for sealing, caulkingand glazing in buildings and related construction.
In Test Method Athe Wet Film Thickness Gage English or Metric graduation is used to measure wet film thicknessed up to 60 mils on the English scale series, and up to mm on the metric scale series.
This test method covers the measurement of the wetting tension of a polyethylene or polypropylene film surface in contact with drops of specific test solutions in the presence of air. It is calculated from the weight or volume of the paint solids sprayed and that of the paint solids deposited on the painted part. This test method covers measurement of the pressure-sensitive tack of adhesives.
Seta Zahn Cup No. 3
It is intended to determine whether the working life conforms to the minimum specified working life of an adhesive required by consistency tests or by bond strength tests, or by both.
This test method covers the determination of the quantity of adhesive solids applied in a spreading or coating operation.
Conditions are specified for the testing of a wide range of papers considered to be of low absorbance or non-absorbent, including release papers, sized, coated, or un-sized papers designed for printing, writing, wrapping, and similar tasks where the paper surface interaction with aqueous or solvent based inks or other aqueous or non-aqueous liquids is important.
Measurements are applicable to spindle, disk, T-bar and coaxial cylinder viscometer.
The uncertainties of extrapolation should be considered in deciding upon the length of the test. Standard Practice for Conducting Creep Tests of Metal-to-Metal Adhesives This practice covers the determination of the amount of creep of metal-to-metal adhesive bonds due to the combined effects of temperature, tensile shear stress, and time. Limitations include the ability to accurately astn the amount of paint solids deposited on the part and the capability of accurate measurement of the amount of paint sprayed.
For materials which absorb the test liquid under the specified test conditions, the rate of change of the contact angle as a function of time may be significant, and may be determined using procedures described in this test method.
The test method is only one of several available for the measurement of tack and is not recommended for the specification d1804 end use products. This test d108 measures the contact angle of a test liquid in contact with a flat specimen of a film or a paper substrate under specified test conditions. This test method covers the measurement of the apparent viscosity of shear-rate-dependent adhesives. This practice covers the determination of the amount of creep of metal-to-metal adhesive bonds due to the combined effects of temperature, tensile shear stress, and time.
This test method is applicable to both gun and knife grades. Hand-held micrometer for measuring coatings applied to plane rigid surfaces. This practice covers two procedures applicable to all adhesives having a relatively short working life. This test method covers the detection of the presence of hydrophobic non-wetting films on surfaces and the presence of hydrophobic organic materials in processing ambients. This practice provides d10844 procedure for the estimation of the quantity of liquid adhesive applied in a spreading or coating operation.
Additional instruments that can perform the procedure in this test method may also provide equivalent results. This test method describes a procedure to measure slump, or sag, resistance of a trowel-grade carpet adhesive using a button slump test apparatus.
This test method is applicable to self-levelling and non-sag grades of sealant. This test method is not applicable to coatings that will be readily deformable under the load of the measuring instruments, as the instrument probe must be placed directly on the coating surface to take a reading.
This test method covers the determination of the creep properties of adhesives for bonding metals when tested on a standard specimen and subjected to certain conditions of temperature and tensile stress in a spring-loaded testing apparatus.
A standard liquid ink for making measurements is described. These test methods cover the determination of wet film thickness of organic coatings such as paint, varnish and lacquer. It is also possible to evaluate the absorptive properties of a surface, as the remaining liquid volume on top of the specimen surface is measured as a function of time.
The test method provides a visual evaluation to relate troweled bead profile and trowel pickup. Two types of apparatus for measuring the contact angle using the procedure in this test method are described.
