QTZ paint film cone bending tester

QTZpaint filmCone bending tester

Instructions:

QTZpaint filmThe cone diameter of the cone bending tester varies, allowing the coating to stretch at different diameters and accurately evaluate its adhesion performance. This product is based onGB/T 11185TheISO6860-84Designed and manufactured according to standard standards, it is mainly used to test the resistance of coatings for paints and varnishes to cracking or peeling off from metal substrates when bent around a conical axis under standard conditions. It has the advantages of small size, light weight, and easy operation.

Main technical parameters:

Cone shaft made of stainless steel (large end)ф38mmSmall endф3.2mm, Long203mm）

Measurable maximum width up to20.3mm（8Inches) and1.6mm（1/16Inch thick test panel

Test piece thickness:0.3～0.8mm(Hard substrate)

0.3～5.0mm(Soft substrate)

Test piece size:19×11cm

Overall dimensions:300×120×80mm(Long)×wide×High)

heavy Quantity:8Kg

Operation steps:

Carefully cover the surface of the paint film with paper and clamp it between the cone shaft and the operating rod, then clamp the fixing plate.

Bend the test panel along the cone axis using a manual lever

In15Bend the sample with uniform force within seconds180degree

Remove the paper and inspect the areas where the paint film has cracked

Record the location of the crack and measure the distance from the crack to the smallest edge of the bending axis diameter

The elongation value of the paint film can be determined from the calibration curve
