Kronitex KP-140 is an essential component in Floor Finishes and Sealers, acting as a permanent plasticizer and leveling aid.
Kronitex KP-140 imparts plasticizing characteristics to water-based acrylic Floor Finishes and Sealers that aid in film formation, improvement of wetting-leveling and gloss, and achieving a "dry bright" appearance.
Kronitex KP-140 can also help to reduce surface flaws such as streaking and powdering.
Kronitex KP-140 is a chemical product also known as Tributoxyethyl Phosphate (TBEP).
Kronitex KP-140 acts as a plasticizer, a flame retardant, and a leveling agent in various industrial applications.
Kronitex KP-140 is a high-performance chemical additive consisting of 100% Tributoxyethyl Phosphate (TBEP).
Kronitex KP-140 is a multi-functional alkyl phosphate ester that acts simultaneously as a plasticizer, a leveling agent, a coalescent aid, and a flame retardant.
Core Functional Mechanisms
Wetting and Leveling Aid: In emulsion polymers and water-based coatings, Kronitex KP-140 acts as a surface-tension modifier.
Kronitex KP-140 eliminates surface flaws like streaking, crazing, and powdering, ensuring a smooth, high-gloss "dry bright" finish.
Film Coalescence and Plasticization: Kronitex KP-140 lowers the Minimum Film Forming Temperature (MFFT) of polymers.
By interspacing itself between polymer chains, Kronitex KP-140 functions as a permanent secondary plasticizer that dramatically improves low-temperature flexibility in plastics, acrylonitrile rubbers, and elastomers.
Rapid Knockdown Defoaming: Kronitex KP-140 is an extremely efficient anti-foaming agent used during liquid manufacturing processes.
Kronitex KP-140 functions reliably across extreme pH ranges and temperatures to suppress micro-foam and macro-foam.
Viscosity Modification: When added to vinyl plastisols and water-based adhesives, Kronitex KP-140 reduces initial viscosity and aids system dilution, making the mixtures easier to pump, pour, and spread.
Industry / Primary Role / Specific Benefit:
Floor Care & Finishes: Leveling agent & Permanent plasticizer: Prevents powdering; improves gloss on acrylic finishes.
Paints & Coatings: Coalescent & Pigment wetter: Enhances rheology and uniform color spread without hurting gloss reflectance.
Adhesives & Sealants: System diluent: Optimizes open time and spreadability in water-based adhesive formulations.
Rubber & Elastomers: Low-temp plasticizer: Keeps rubber components flexible in freezing conditions (e.g., medical rubber stoppers).
Textile & Paper Processing: Industrial defoamer: Suppresses manufacturing foam during high-speed paper coating and fabric dyeing.
Key Uses
Adhesives: Kronitex KP-140 is used as a system diluent and flame retardant in water-based glues.
Floor Polishes: Kronitex KP-140 acts as a leveling aid and coalescent agent.
Polymers: Kronitex KP-140 helps soften plastics and adds fire-resistant properties without halogens.
