Surface Energy Of Acrylic Sheet

Therefore the surface tension of the liquid and the surface energy of the material must be matched for the application.

Surface energy of acrylic sheet.

The dynamics of wetting watch video are described below. If the material surface energy is too high then the paint ink or coating may bleed or be difficult to control. The surface energy values of some typical materials are shown in the two tables. For glazing applications continuously imposed design loads should not exceed 750 psi 5 2 mpa at 73 f 23 c.

The measured surface energy 27 to 31 mj m 2 was sensible as surmised from their structure. Acrylic acid content increases the surface energy threshold adhesion energy and adhesion hysteresis of psa lns. The surface energy of the plastic either allows or prevents wetting the surface. The first table shows values for low and high surface energy solid materials whilst the second table.

300 lse low surface energy acrylic 300 f bonds well to lse surfaces outstanding adhesion to low surface energy plastics powder coated paints and lightly oiled metals good chemical and humidity resistance. Acrylic acid aa was co polymerized with 2 ethyl hexyl acrylate 2 eha and 1 6 hexane diol diacrylate hdda to create psa lns. Different forms of surface preparation can increase the surface energy which increases wetting. Spreading a b c where.

Although the tensile strength of acrylite ff sheet is 10 000 psi 69 mpa at room temperature astm d 638 stress crazing can be caused by continuous loads below this value. Sheet sizes from 10 x 10 to 65 x 130.
