SWD 1929F Quik-Shield ® ACRYLIC ELASTOMERIC COATING
DESCRIPTION:
SWD 1929F Quik-Shield ® coating is a high solids, heat resistant, water based elastomeric coating material made from 100% ACRYLIC POLYMERS. It is specifically designed to protect sprayed rigid polyurethane foam used as insulation on roofs and storage tanks from degradation caused by normal weather, aging and ultraviolet exposure. SWD 1929F Quik-Shield ® coating is also approved for use as a "General Purpose Fire Retardant Chemical Coating."
CALIFORNIA TITLE 24
SWD 1929F Quik-Shield ® coating is made from 100% ACRYLIC POLYMERS and meets California Title 24 COOL ROOF MANDATE with 83% Solar reflectance and 95% Thermal Emittance. This standard is the mandate for cool roofs in California Oct 1, 2005
CHARACTERISTICS
FLAME RETARDANT:
It is rated Class I under UL 723, Rated Class 'A' under UL 790 and listed by ICC over a variety foam thickness', densities and roof inclines. It meets UL coating requirements for Roof Construction Systems # 136, 181 and 205 and is listed with the California Fire Marshall both as a component of Class A rated roof systems and as a "General. Purpose Fire Retardant Chemical Coating."
EXCELLENT ADHESION:
To rigid polyurethane foam, concrete masonry, wood, and metal
MOISTURE PROOF:
Not water proof. Perm rating of 3.5 allows the dried film to "breath," allowing vapor movement and preventing pressure buildup which can cause roof blisters.
HEAT RESISTANT:
A reflectance rating or 83% acts to impinge or block the flow of heat and in combination with the rigid polyurethane foam, produces the most efficient roof insulation system available in the marketplace today. To enhance the life expectancy of the coating and to improve heat resistance, white or light pastel shades are recommended.
HEAT RELEASE:
A thermal emittance of 95% acts to release stored heat in the roof out though the coating helping to create a cooler roof.
WEATHER RESISTANT:
To give optimum protection to the insulation foam, SWD 1929F Quik-Shield ® coating contains 100% ACRYLIC POLYMERS for durability and titanium dioxide which acts to block the harmful effects of ultraviolet light.
It was exposed for more then 8000 hours, in a weatherometer, (equivalent to 20+ years of natural exposure) without showing any deterioration in the foam or coating.
In addition, since 1977, in an ongoing test by the Naval Civil Engineering Laboratory (NCEL), SWD 1929F Quik-Shield ® coating sprayed over SWD Foam has been subjected to natural exposure at seashore, desert and mountain test sites with the following results: SWD 1929F Quik-Shield ® was one of only 3 out of 54 coating systems rated "Excellent" at all three sites No deterioration of coating or foam. SWD 1929F Quik-Shield ® was recommended for use at any and all locations as a protective coating for foam."
SWD 1929F Quik-Shield ® coating is currently being tested in a new CRRC 3 year study for continuing solar reflectance and Thermal Emittance in 3 more geographic locations around the country
MILDEW RESISTANT:
Contains mildew-cides to inhibit or prevent mildew growth..
ADVANTAGES:
High degree of fire retardant, 100% ACRYLIC POLYMERS, low pigment to polymer ratio, no plasticizers, low odor, nonpolluting (no organic solvents), water cleanup, ready to use (no catalyzing), excellent vertical hold allowing uniform build on highs and lows of foam texture.

INSTALLATION:
SWD 1929F Quik-Shield ® coating as been designed to be applied by brush, roller or conventional airless spray equipment. Tools can be cleaned with a thorough water flush.
The foam surface should be dry, clean and free of contaminants or oxidation.
To avoid damaging the skin of the foam, operator should wear soft soled shoes.
SWD 1929F Quik-Shield ® coating is a high reflectance coating, It is recommended that operators wear sunglasses to avoid temporary blinding effects due to glare.
Do not apply to ambient temperatures below 50`F
The coating should be applied from (2-72) hours after the foam is installed.
