Revision date: April 2011 POLYLITE 32245 Series Polyester Engineered Marble Resin DESCRIPTION The POLYLITE 32245 series resins are light amber colored, resilient, medium reactivity, low viscosity, casting resins. These unsaturated polyester Hybrid resins are pre-promoted for room temperature cure using Methyl Ethyl Ketone Peroxide. APPLICATION The POLYLITE 32245 series was developed as a matrix resin suitable for casting integral bowl vanities, wall panels, shower pans and bathtubs when using marble quality carbonate, trihydrate and lightweight type fillers. They can be used in conjunction with hand mix or automated dispensing equipment. The POLYLITE 32245 series resins were developed to provide a versatile low viscosity and low styrene/voc alternative. The inherent low viscosity allows higher filler loadings and subsequently can contribute to lower material cost of cast parts. Utilizing light weight fillers can reduce cast part material cost (at equivalent resin cost per pound) and weight. Marble vanities made with the POLYLITE 32245 series were tested and exceeded the 500 cycles under ANSI* Thermal Shock Standards. * American National Standards Institute, Inc., 1430 Broadway, New York, NY 10018 FEATURES Low Viscosity Certification for quality, finished parts Contains less than 35% Styrene Specially promoted Produced Utilizing Statistical Process Control (S.P.C. & S.Q.C.) Techniques BENEFIT - Permits high filler loading to reduce part material cost. - Excellent wet-out and air release. - Recommended resin for light weight fillers. - Minimal resin demand when used with light-weight fillers. Passed all Tests in accordance with ANSI Z124.3 for engineered marble. California Rules 50 and 1162 Compliant -Low part exotherm -Low shrink -Improved shelf stability Batch-to-batch Consistency Uniformity

TYPICAL USE GUIDELINES POLYLITE 32245 marble resins are designed for use with fillers commonly used in the manufacture of engineered marble. Physical properties of filled compositions are influenced by many factors under the manufacturer s control, such as filler type/particle size distribution/concentration, ambient temperature, pigments, initiator type/level, cross sectional area of the finished part and part configuration.. Filler interaction with the resin affects the final color of the product and can influence the gel and cure rate. Careful evaluation of these factors must be considered before use. Initiator levels should be maintained within a range of 1.25%-2.50% by weight based on resin weight. Initiator levels below 1.00% MEKP will result in extended gel and cure rates and are never recommended. If longer cycle times are required select one of the longer gel time versions Polylite 32245-16, -40 or -45. The POLYLITE 32245 series was developed as a matrix resin suitable for casting integral bowl vanities, wall panels, shower pans and bathtubs when using marble quality carbonate, trihydrate and especially lightweight fillers. It can be used in conjunction with hand mix or automated dispensing equipment. In the manufacture of integral bowl vanities using a two-pour method, it is suggested that the resin/filler ratio be selected in each step and that the initiator level is established to give the working time needed without creating manufacturing issues. Although the type and content of filler can influence the gel time and cure rate, filled systems employing 76-81% Filler, 19-24% POLYLITE 32245-12 demonstrated the following characteristics in actual production environments: Initiator % Gel time (minutes) Temperature F Filler Type Superox 46709 1.00 40 77 CaCO 3 Superox 46709 1.00 34 88 CaCO 3 Superox 46709 1.25 30 85 Light Weight Superox 46709 2.00 20 77 CaCO 3 Atofina Delta X9 1.25 30 80 Light Weight Atofina Delta X9 1.50 30 75 Light Weight 900 1.25 30 80 Light Weight 900 1.50 35 74 Light Weight 925 2.00 20 77 CaCO 3 MEKP9 1.00 24 88 CaCO 3 MEKP9H/Azox 2:1 Ratio 1.50 35 72 Light Weight Page 4
The following matrix formulations are provided as suggested guidelines for using the POLYLITE 32245 series resins. Processing conditions such as resin and work place temperatures, filler concentration and type initiator concentration and type, mass of part etc will influence gel, cure and demold time of parts made with POLYLITE 32245. Therefore the suggested guidelines are offered as starting formulations only and will require adjustments to optimize processing by fabricators.

STORAGE To ensure maximum stability and maintain optimum resin properties, resins should be stored in closed containers at temperatures below 75ºF (25ºC) and away from heat sources and sunlight. All storage areas and containers should conform to local fire and building codes. Drum stock should be stored away from all sources of flame or combustion. Inventory levels should be kept to a reasonable minimum with first-in, first-out stock rotation. This resin should not be stored in HDPE containers.
