Datasheet (PDF) Collomix KR160HF Mixing Paddle. For use with flooring fillers, cement, sealing compounds and tile adhesives. The KR mixing paddle generates high shear forces which prevent the formation of lumps and ensure that the material is homogenized quickly. The crossbar helps scrape material cleanly off the bottom of the tub. The mixing tool has good corner smoothness in the tub. Easy to clean because material hardly sticks.
