F-753 Muraculon is a unique vinyl based coating that when spray applied provides a durable, flexible protective coating on polyurethane foams. F-753 can also be used on molded polyurethane and closed cell foam containing vinyl.

F-753 Muraculon coating is most commonly used as "edge spray" for noise deadening/ insulation foam products for over the road, heavy equipment and agricultural equipment. F-753 is a tough coating that adds durability, moisture, heat, UV, abrasion, puncture and chemical resistance to foam products used in severe conditions. F-753 is also used for protecting acoustical panels for interior noise abatement. F-753 is also performs well for protecting polyurethane foam packaging and case inserts, preventing FOD. F-753 Muraculon is an excellent, cost effective replacement for Hypalon® coating.

Mixing Instructions

N/A QUALITY CONTROL RECOMMENDATIONS FOR SPRAY AND DIP APPLICATIONS.
Like most liquid vinyl, F-753 may coagulate during storage, requiring thorough remixing agitation before use each day. For best results, a (Contact Plasti Dip International Technical Service for specific equipment recommendations.) high speed air/explosion proof electric drum mixer along with a Cowles® or dispersion blade gives the maximum combination of high shear, excellent flow and circulation. Diameters of 3" for mixing five gallon containers and 7" for mixing 50 gallon drums. Note: It has been found that the dispersion blades are highly effective, fast and produce more shearing action than can be obtained from a standard mixing blade or paddle.
After the F-753 has been agitated thoroughly, it should last 8 to 10 hours depending on your spray equipment and temperature. Avoid making solvent additions before mixing. Check viscosity. Some adjustments may be necessary for your particular use. Contact technical service for specific applications.

Prime coat: Set pot pressure at 20-25psi and atomizing at 30-50psi, open pattern adjustment for a 2"- 4" pattern at 6"-10" from surface. Aim spray gun at foam and fully trigger spray gun. Open material adjustment until a uniform, wet splatter appears on the foam. The wet splatter should melt or flow into the surface of the foam. Coat all sides (except bottom) with an overlapping motion. Make sure all corners and edges are thoroughly primed. The prime coat should be wet to the touch but should not completely color or cover the foam. Its purpose is to wet or prime the surface for the sealing coat, a necessity for proper adhesion.

Seal coat: After the prime coat has been applied, immediately begin sealing the foam by only partially pulling the trigger back from its previous setting until a dry, web coating appears. This seal coat should appear lighter in color than the prime coat. Hold gun approximately 6"-10" from surface and use an overlapping motion, being sure to completely seal the surface. If seal coat is applied too dry, poor adhesion will result. If applied too wet, sealing surface may become difficult. Again, seal all sides (except bottom), being sure to check entire surface for complete seal.

Finish coat: After seal coat has been applied, immediately begin applying the finish coat by fully triggering spray gun as in prime coat. Holding the gun 6"-10" from surface, apply a uniform splatter coat using an overlapping motion. Apply the finish coat as desired in thickness and texture. The finish coat is necessary to increase seal coat strength and durability. Allow the finished coated part to dry to the touch (see caution), minimum 5 minutes, then return to prime coat, seal coat and finish coat bottom of part. Follow instructions and be sure to pay close attention to corners and edges on all steps.

Caution

N/A It is important to apply all coatings at once. Do not allow to set more than 10-20 minutes or subject to heat. This causes an anti-block additive to come to the surface which will not allow additional coats to adhere.

To accelerate final drying, place coated object in ventilated oven at 100ºF-140ºF for 5 minutes. Make sure heat source is safe for this use and that you ventilate properly. To increase coating speed, you may increase atomizing pressure; open material adjustment and pattern adjustment to your comfort level.
