Quicktest 38S Poly Test Pen serves to check if the treatment of polyolefins (polypropylene, polyethylene, polybutylene) has shown an effect onto the material. A stroke of the pen leaves a full line on the material if the materials surface energy has a value of ca. 38 mN/m or more. If the material’s surface energy is below ca. 38 mN/m, the fluid contained in the pen will form small drops on the surface. The fluid applied to the surface will dry within seconds, it does not need to / cannot be wiped off anymore.

• Extremely easy to handle
• Perfect for quick spot checks on polyolefins
• No wiping off necessary, lasting display of result
• Good readability by striking red coloring

Attention: The test fluid of the Quicktest 38S Poly Test Pen contains solvent. This might cause wrong results being displayed on materials or surface coatings not being solvent resistant!
