Tennants as distributor for Vink Chemicals are pleased to offer a new range of Kimicell thickeners.
Available in a range of low, medium or high viscosities, the Kimicell Hydroxyethyl Cellulose is used as a thickener for water-based paints and coatings. They are also used as admixture performance enhancers.
They also offer bio-stable grades, offering better resistance than most other soluble gums and polymers and this resistance to enzymatic and chemical degradation elicits a more stable viscosity.
It increases the paint/coating in can viscosity, sag resistance (especially in combination with HEUR) and enhancing coverage. It also provides good water-retention, rheology and colloid protection, especially when used in those solutions where a non-ionic material is desired. It reduces sedimentation of the pigments and fillers and can also contribute to the dispersion of pigments by improving the flow during grinding, helping to stabilize the pigment from flocculation. In admixtures they can also be used to improve the properties of mortars such as water-retention, workability & open time.
Normal dosage is 0.4-0.8% w/w. Paint made from the lower molecular weight grades are more resistant to spatter during roller application for example.
