Polytrol GFT Poly-Resyn Rheology Modifiers / Thickeners Epoxy (EP) Polyamides (PA) Rubber - Elastomer (Chloroprene, Butyl …) SEALANT ADHESIVE SEALANT >> Putty POLYTROL GFT is an improvement over POLYTROL FT. It disperses more quickly while providing all of the properties of POLYTROL FT. The improvement involves modification of the individual particles enabling better dispersion efficiency,--more effective swelling and gelling. POLYTROL GFT is superior to POLYTHIX GM. Demonstrating in a Warring blender (typical mineral spirits system with no pigment), POLYTROL GFT will reach a Hegman reading (fineness of grind) in a shorter period than POLYTROL FT. Conversely, by the same procedure, for a given time period the Hegman reading will be superior to that for POLYTROL FT. Typical of the organic thixotropes, POLYTROL GFT imparts a characteristic,--"butteryness", advantageous to coatings, inks, adhesives, caulks and sealants. Viscosity increase, rapid development of thixotropy, pigment suspension, optimum balance between sag control and leveling, penetration control, no affect on color, gloss, water resistance or durability, maximum rheological value. Rheology modifier. Provides a high degree of thixotropy in adhesives, caulks, sealants, putties and mastics. Disperses very quickly and possesses effective swelling and gelling. Increases viscosity. Offers rapid development of thixotropy, pigment suspension, optimum balance between sag control and leveling, penetration control, no affect on color, gloss, water resistance or durability and maximum rheological value. Use level : 0.5%-1.5% by weight on the total composition.
