Carboset CR-785 Acrylic Copolymer Latex TECHNICAL DATA SHEET

Transcription

1 Acrylic Copolymer Latex TECHNICAL DATA SHEET General Description Carboset CR-785 is an acrylic copolymer latex designed for air or forced dry coatings on wood, metal and plastic substrates. Carboset CR-785 resin can be formulated into clear or pigmented finishes suitable for both DIY and industrial (OEM) coatings. Carboset CR-785 resin is readily coalesced with both ethylene and propylene glycol ethers. This polymer can be readily formulated into brush, roll, spray, dip or flow coatings. Carboset CR-785 resin has excellent gasoline and solvent resistance, making it suitable for automotive ancillary and general industrial finishes. These same hydrocarbon resistance properties, coupled with fast dry and low MVTR (Moisture Vapor Transmission Rate) make Carboset CR-785 resin an excellent choice for concrete curing membranes and sealers. Carboset CR-785 resin can be blended with Sancure 1514 dispersion, waterborne aromatic polyurethane, for additional toughness and wear resistance, when formulated for clear wood finishes for trim and flooring. Suggested Applications Acrylic and acrylic-urethane clear wood finishes Clear wood floor finishes Clear concrete sealers Concrete curing membranes General Industrial finishes Automotive metal and plastic finishes Business machine coatings Implement enamels Performance Features Compatibility with waterborne urethanes High gloss Excellent water and humidity resistance Fast dry Excellent gasoline and solvent resistance Excellent impact resistance Passes ASTM C-309 Concrete Curing Membrane Test 5.1, Water Retention Typical Physical Properties* Appearance Milky White Emulsion Total Solids by Weight, % 42.5 Total Solids by Volume, % 41.0 Density, pounds/gallon 8.56 Density, specific gravity 1.03 Brookfield Viscosity, 25 C, #1 Spindle, cps 40 ph 8.0 MFFT 44 C Volatiles Water, Ammonia Mechanical Stability, 15 minutes, Waring Blender Satisfactory Freeze/Thaw Stability Protect from freezing *Property values represent typical results only and are not to be considered specifications.

6 Page 6 Typical Performance Data CONCRETE SEALER HOT TIRE PICK-UP RESISTANCE TEST Concrete Sealers used on driveways and garage floors will be subject to warm tires on vehicles which are parked after being driven. This test determines the resistance of the sealer to lifting or black marking from the hot tire under pressure. The tire tracking is simulated by attaching a hot, wet tire section to the surface of the sealed concrete with ordinary C clamps. Imprint of the tread mark, lifting of the coating, and black mark left on the coating are evaluated in this test. Apparatus Used 1. Paint Brush 2. Cheese Cloth 3. C Clamps 4. Aluminum Panels 5. Tire sections (2.5 X4 ) with two treads. (The tire can be slightly worn but have good tread remaining.) 6. Concrete plaques (4 X 8 X 0.5 ) 28 day cure F Oven Procedure 1. The concrete plaques are coated twice with a brush at a uniform spreading rate of 200 sq. ft./gal. and allowed to air dry for 7 days. 2. The sealed surface that is to be tested is soaked with moist cheesecloth for one hour. (Cheesecloth removed just prior to application of tire section.) 3. The tire section is placed under 140 F running water for one hour. 4. The tire section is then clamped tightly to the sealed surface using two C clamps and the metal panel to uniformly distribute pressure. 5. Test Method A: Apparatus remains clamped for 24 hours at room temperature. Test Method B: Apparatus remains clamped in 140 F oven for 1 hour. (Very severe.) 6. The tire sections are then carefully removed and the coatings are evaluated for imprint of tread mark, lifting of the coating, amount of black marking. Report 1. Type of Test: Method A or B 2. Test Results: Rate: Imprint of =No Imprint Tread Mark 0=Severe Imprint Sealer Adhesion =No Removal in area of Tread 0=Completed Removal Black Tread Mark =No Mark on Sealer 0=Severe Black Mark

17 Page 17 Suggestions and Raw Material Information DISPERSANTS We have found excellent results with the use of sodium-based dispersants such as BYK 155 and Tamol 850. To date, we have not found any negative impact on water resistance when using these dispersants. Other dispersants may also provide excellent results. BYK 155 BYK 301 Tamol 850 Surfynol 502 BYK Chemie BYK Chemie Rohm & Haas Air Products COALESCENCE Carboset CR-785 must be coalesced to form a continuous film. A coalescent level of minimum 35%, based on resin solids is recommended as a starting point. Both ethylene and propylene-based glycol ethers can be used. Plasticizers such as butyl benzyl phthalate or dibutyl phthalate can be used as needed to improve coalescence and flexibility.
